Some nights it’s easier to fall asleep than others. But for certain people, needing over 20 minutes to fall asleep every night is a given — and sometimes others have to wait hours more. The causes of insomnia can be due to all sorts of physical and medical health conditions, so it’s important to examine all of the factors that may be creating your difficulty falling asleep.

Falling asleep can say a lot more about what’s going on with your body than just how tired you are. “The amount of time it takes to fall asleep is known as ‘sleep latency,'” Conor Heneghan, lead research scientist at Fitbit, tells Bustle. “A normal amount of sleep latency is approximately 15-25 minutes, which is considered the ‘sweet spot’ for your body to drift into light sleep stages. However, sleep latency is impacted by [a variety of] factors.” These factors can be anything from what you’ve eaten that day, or whether you’ve altered your bedtime routine, to a more serious underlying medical condition that’s making it difficult for your body to rest at night.

And while having trouble falling asleep can be caused by a myriad of health issues, falling behind on sleep can cause sleep debt and add to these problems. So if you realize you’re taking more than 20 minutes to fall asleep every night, asking your doctor about this problem may get you some relief.

Here are nine health issues that not being able to fall asleep in 20 minutes could be a sign of, according to experts.

GERD, or gastroesophageal reflux disease, can cause symptoms that aren’t quite apparent until you lie down to try to fall asleep.

“When lying down, it’s easier for stomach acids to flow up your esophagus, causing heartburn,” Terry Cralle, RN, clinical sleep educator and sleep consultant for Saatva, tells Bustle. “Heartburn, in turn, can disrupt falling and staying asleep. That’s why many people with GERD experience an increase in symptoms at nighttime and may have trouble finding a comfortable position for sleeping.” Avoiding GERD trigger foods like spicy food, coffee, and alcohol, in the hours before bed, may provide some relief.

Anxiety doesn’t exist solely in the mind. If you’ve been dealing with feelings of stress and nervousness in your daily life, it may be building up and causing it to be difficult for you to fall asleep.

“Those who experience anxiety have a complex relationship with sleep,” Dr. Sujay KansagraMattress Firm’s sleep health expert, tells Bustle. “Anxiety can not only prevent someone from falling asleep but it can also be worsened once a person experiences the effects of sleep deprivation.” Dr. Kansagra recommends talking to your doctor if stress or anxiety may be affecting your ability to fall asleep.

If falling asleep regularly takes more than 20 minutes for you, and you also experience respiratory symptoms, this could be caused by asthma.

“Asthma symptoms often worsen at night, [including symptoms of] nighttime coughing, chest tightness, wheezing and breathlessness: a condition referred to as ‘nocturnal asthma,'” Cralle says. Check in with your doctor if you realize that these sorts of symptoms tend to come along at night.

4“Social Jetlag”

Keeping a completely different sleep schedule on weekdays and weekends can make falling asleep more difficult in general.

“Another major factor that may contribute to longer sleep latency is ‘social jetlag,’ brought on by the shift in sleep schedules that many experience on days off compared to workdays,” Heneghan says. This issue with your circadian rhythm can be addressed by keeping a more consistent bedtime and wake up time throughout the week.

If you have general aches and pains, and they worsen at night enough to make it difficult for you to fall asleep — you may have undiagnosed arthritis. And arthritis doesn’t only affect older people.

“It is estimated that as many as 80 percent of people with arthritis have difficulty sleeping,” Cralle says. “Pain makes it hard to get comfortable and to fall — and stay — asleep. Since sleep deprivation makes pain worse, it’s critical that arthritis sufferers get enough quality sleep.” So talking with your doctor both about your pain and your sleep problems can be a step in the right direction.



Like arthritis, menopause is associated with aging but can show up in young peopleas well. Since you may not realize this is possible, you may not be connecting the dots between potential gynecological issues and lack of sleep.

“Women are twice as likely to suffer from insomnia than men, according to the National Sleep Foundation, and their sleepless nights have been linked with hormonal changes —especially during menopause, when hormone levels are erratic,” Dr. Kent Smith, founding director of Sleep Dallas, tells Bustle. Making sure you regularly see an OB/GYN, and always tell your doctors about changes to your health, can help you stay on top of these potential issues.

7Restless Leg Syndrome


Tossing and turning doesn’t have to be something that you ignore. Health issues like restless leg syndrome could be seriously impacting your ability to fall and stay asleep.

“Approximately one in 10 adult Americans suffer from Restless Leg Syndrome, according to the National Sleep Foundation,” Dr. Smith says. “This sleep-related movement disorder causes overwhelming and often unpleasant urges to move the legs while at rest, often making it difficult for sufferers to drift off to sleep.” If you find it particularly hard to lie still at night, it may be best to get in touch with a doctor.

8Sleep Apnea


While sleep apnea is known to cause disruptions during sleep, it can cause difficulties during the process of falling asleep as well. And since sleep apnea can be difficult to diagnose, you might not connect the dots on this sleep disorder immediately.

“Sleep apnea, a condition in which a person ceases to breathe multiple times per hour when they sleep, can inhibit a person’s ability to fall asleep,” Dr. Smith says. “The brain detects that it is receiving less oxygen during sleep, so, in a life-preserving attempt, it actively prevents the sufferer from falling asleep.” If you have difficulty falling asleep, plus other signs of sleep apnea, then it’s important to see a sleep specialist and seek treatment.

9Vitamin Deficiency

Ashley Batz/Bustle

Sometimes, the root cause of your difficulty falling asleep can be hard to pinpoint but relatively straightforward to treat. One of the examples of this is vitamin deficiency.

“Several common vitamin deficiencies can lead to sleep disturbance,” Arielle Levitan, M.D., co-founder of Vous Vitamin LLC, tells Bustle. “[…] Determining which vitamins to take and in which safe and proper doses is important.” Particular deficiencies like magnesium and iron can cause difficulty falling asleep, Levitan says. To find out if this is a problem, the first step is to speak with your doctor and potentially have them perform blood tests to check for deficiencies.

In order to protect your physical and mental health, it’s important not to normalize your difficulty falling asleep. Taking note of why you may be struggling to fall asleep within 20 minutes or so, and how you feel the next day, may provide you some of the data you need to discuss this issue with your doctor — and find a treatment that works for you.

Prepare Yourself For The Best Night’s Sleep

Author Article

Getting a good night’s sleep requires more than plopping down on your bed. In fact, sleep is an active process. While we snooze, we pass through several stages of sleep, each with its own distinct physiological changes. We also alternate between non-REM (rapid eye movement) — which serves to restore the body — and REM sleep, during which we dream and restore the brain. The time you spend in these stages varies by age, but a good night’s rest means the sleep should be continuous and uninterrupted.
Dim the lights throughout the house this evening. Gradually reducing the amount of light in your home will mimic the way sunlight goes down and help trigger sleepiness.
The urge to sleep is dictated by two natural forces. Our homeostatic sleep drive helps us balance our wakefulness with sleep. “It tells us we’re only good for so many hours of alertness before we become functionally intoxicated,” says Helene Emsellem, MD, director of the Center for Sleep and Wake Disorders in Chevy Chase, Maryland, and author of Snooze or Lose. Our circadian rhythm, on the other hand, regulates the timing of our sleepiness and wakefulness. You can thank your circadian rhythm for that daily afternoon slump, for instance.
Both forces are highly affected by our habits, our routines and even our exposure to sunlight. So, for truly sound slumber, it’s important to respect these internal drives and do things that gear your body for sleep — some folks call this practicing good sleep hygiene. Here’s how you can ensure that you’re properly prepped for a good night’s sleep.
Move That Body
A good workout that gets your heart pumping and muscles flexing works wonders on promoting sleep. Regular physical activity makes it easier for you to get to sleep and improves the quality of your sleep. For maximum benefit, avoid rigorous activity three to four hours before bed. Body temperature rises when you exercise, which can make it hard for you to get to sleep.
Get Some Sun
Exposure to sunlight influences circadian rhythm, which is controlled by brain cells in the hypothalamus. These cells respond to light and dark signals from our environment, and set off reactions in our bodies to either wake us up or make us sleepy. In the mornings, it triggers the release of cortisol, a stimulating hormone, which raises body temperature. “Sunlight is a strong stimulus for wakefulness in humans,” says Nancy Foldvary, DO, director of the Sleep Disorders Center at the Cleveland Clinic and author of The Cleveland Clinic Guide to Sleep Disorders. “So, getting sun exposure promotes wakefulness during the day and can help people sleep at night.” Darkness, on the other hand, triggers our brains to produce melatonin, a hormone that regulates circadian rhythm and promotes sleepiness.
Create A Sanctuary
Think of your bedroom as your private retreat where you go every night to be renewed. Here’s how to turn it into the ideal environment for sleep:
Look For A Mattress And A Pillow That Are Comfortable
Preferences for bedding vary widely, so be sure to test out a mattress for a good 15 minutes before you buy.
Set The Thermostat On The Cool Side
Body temperature naturally falls at night. By keeping the room cool, your body will mimic its surroundings.
Darken The Room With Shades And Curtains To Keep Out Light
You might even try using an eye mask. Darkness helps stimulate the production of melatonin, a hormone that promotes sleepiness.
Ditch the Electronics
Clear your bedroom of TVs, computers, and any other electronics. These gadgets emit blue light, which like any light, can cause wakefulness at night and disrupt the body’s natural inclination to sleep. Use your bedroom only for sleep (and sex), so you won’t associate it with any other activity.
Don’t Smoke
Poor sleep is just one more reason you shouldn’t light up. Smokers are four times more likely to report feeling unrested after a night’s sleep than nonsmokers. The smokers also spent less time in deep sleep and more time in light sleep. Smoking before bed pumps your body with nicotine, a stimulant that can keep you up at night. It also raises overall body temperature and elevates your heart rate and metabolism — all of which will keep you awake. To make matters worse, smokers go through withdrawal when they’re asleep, which disrupts their sleep, too.
Stick With A Routine
It doesn’t matter whether you soak in the tub, read a good book, or listen to your favorite music, the key is doing the same thing every night, so your body gets the signal that you’re prepping for sleep.
And, okay, we know you want to sleep in on the weekends and make up for the slumber lost during the week. But, don’t. Get in the habit of waking up and going to bed at the same time every night, even on weekends. Sleeping in on Saturdays and Sundays will only make it hard for you to get to sleep on Sunday night, and you’ll feel less refreshed on Monday.

The Best Foods to Eat for Better Sleep

Nonfat Popcorn

The carbohydrates in nonfat popcorn help bring the amino acid tryptophan into your brain, where it’s used to make a sleep-inducing neurotransmitter called serotonin. Since eating a heavy meal within two hours of bedtime can keep you awake, popcorn (just 93 calories in three cups popped) is a great late-night snack. Choose plain, fat-free popcorn and jazz it up with some curry powder or any of these other tricked out popcorn toppings.

Halibut is packed with two building blocks for better sleep: tryptophan and vitamin B6, and when it comes to seafood, halibut has a mild flavor and meaty texture that appeals to finicky fish eaters. Other foods high in tryptophan include poultry, beef, soybeans, milk, cheese, yogurt, nuts, and eggs.

Mango Lassi

Mango Lassi

Packed with antioxidants, protein, and vitamins, this treat satisfies your creamy, sweet craving as well as ice cream—without the sugar bomb.

BTW, a lassi is basically a smoothie, but it’s always made with yogurt. To make a mango lassi: cut up one fresh, peeled mango and put it in a blender. Add a handful of ice, a small scoop of plain Greek yogurt (go with full-fat dairy for all its health benefits) and a splash of water or milk. Add a dash of stevia for extra sweetness if desired.

Don’t like mangoes? Substitute frozen berries or watermelon.

Garbanzo Beans (Chickpeas)

Garbanzo Beans (Chickpeas)

High-fiber garbanzo beans (or chickpeas) are rich in vitamin B6, which your body uses to produce serenity-boosting serotonin. Try adding garbanzo beans to salads, soups, and stews when you need sleep.

Chamomile Tea

Chamomile Tea

This herbal drink lacks the caffeine found in traditional teas, and it has a calming effect on the body. Also, a warm liquid before bed can make you feel cozy and ready to hit the sheets.

A rise in blood sugar can reduce the production of orexin in the brain. Orexin is a recently discovered neurotransmitter that’s been linked to wakefulness. Try drizzling a small amount of honey in your chamomile tea for a touch of sweet without a full-down sugar rush.

Dried Tart Cherries

Dried Tart Cherries

A handful of dried cherries not only provides the requisite serotonin-boosting carbs, but it’s also one of the few food sources of melatonin, which has been found to promote better sleep and lessen the effects of jet lag. Plus, tart cherries are packed with antioxidants.

The reason behind your epic post-Thanksgiving feast nap is also the secret to helping you sleep better. Tryptophan, an amino acid found in turkey, is known to help calm you down and naturally get you to sleep.

Not feeling a deli turkey sandwich? Try roasted pumpkin seeds, which also contain tryptophan.

Banana  Soft Serve

Banana “Soft Serve”

Frozen bananas make the perfect base for healthy, vegan “nice cream”. and the potassium in them will not only help you fall asleep faster but can prevent those awful cramps (AKA Charlie horses) that wake you up. All you need is the proper blending technique. The trick is to keep blending for several minutes. At first, they’ll just look slimy, but then air works its magic and before you know it frozen bananas morph into a creamy, light treat. Add a handful of chopped nuts for a sweet and salty treat.

Kale Chips

Kale Chips

Don’t knock these roasted green “chips” until you’ve tried them. The hefty dose of vitamin K helps repair and build muscles while you sleep. Simply chop up a bunch of kale, toss with olive oil and sea salt, and spread out and bake at 350 degrees until crispy.

Here’s How Relationships Can Affect Your Sleep In The Long-Term, According To Experts

See Author Article Here
By Julia Guerra

Not to freak you out or anything, but the choices you make today really do have an impact on your future, even in ways you wouldn’t expect. Life is funny that way; sometimes two completely different aspects of life can collide like colors in a messy drawing, and you’re stuck trying to figure out the bigger picture. Take your love life, for example. Did you know your romantic relationships can affect your sleep? I’m not necessarily referring to that can’t-eat, can’t-sleep phase where everything’s coming up roses and you and your partner can’t get enough of each other, either. According to new research, negative relationship experiences in early adulthood might have some unexpected effects on your sleep quality well into your 30s.

According to the American Sleep Apnea Association, 50 million Americans suffer from chronic sleep disorders, while an additional 20 to 30 million report the occasional night of tossing and turning. If you’re among that 20 to 30 million, but haven’t been able to identify the issue just yet, the results of a new study, published in Personal Relationships, a journal of the International Association For Relationship Research, suggest that negative romantic relationship experiences can impact your sleep quality over the long-term. I know, like the negative relationship itself wasn’t bad enough, right?


The study documented the possible correlation between participants’ romantic relationships, stress, and how both of these elements affect sleep quality over the course of adulthood. Researchers recruited 112 participants from the Minnesota Longitudinal Study of Risk and Adaptation and studied them from the age of 23 years old to 32 years old. In the end, per a ScienceDaily press release, the researchers found that people who reported having positive relationship experiences in their early 20s were less stressed and enjoying quality sleep in their early 30s. “Although a large body of evidence shows that relationships are important for health, we are just beginning to understand how the characteristics of people’s close relationships affect health behaviors, such as sleep,” Chloe Huelsnitz, a PhD candidate at the University of Minnesota and lead author of the study, said in a statement, per the ScienceDaily press release.

Generally speaking, says Dr. Tammy Nelson, a sex and relationship expert and licensed psychotherapist, one of the most common emotions that can affect your sleep patterns is anxiety, and as I’m sure you know from experience, no matter how good or bad your relationship is, it can sometimes give you a little bit of stress.

“Being anxious can keep us up at night, prevent sleep, and wake us up once we are asleep,” because it raises blood pressure, increases heart rate, quickens your pulse, and tenses up your muscles, Nelson tells Elite Daily over email. “These are all reactions that are in direct opposition to the relaxation that needs to happen when we are asleep.”

But even after you and a partner eventually decide to part ways, if you’re still dealing with pent-up feelings of stress from the relationship, Natalie Dautovich, an environmental scholar for the National Sleep Foundation, says you can still be affected. “We are physically most vulnerable when we are sleeping, so sleep is most possible when we feel safe and secure,” Dautovich tells Elite Daily.


If you’re reading all of this and thinking “well, that’s pretty unfair,” you aren’t wrong. But the thing is, you still have control over your sleep health, and there are ways to ensure that, no matter what happens in terms of your love life, you’re still doing everything you can to get your rest.

Of course, if you are currently in a relationship, that doesn’t just automatically mean your sleep health, in the short- or long-term, is doomed. In fact, a physical connection with a loved one, such as a hug, kiss, or even sex, can calm your nervous system, therefore decreasing stress and anxiety, making it easier to fall and stay asleep, Nelson explains. However, at the same time, it’s important to remember that having your own bedtime routine of some kind, made up of rituals (taking a warm bath, meditating, journaling, diffusing essential oils, etc.) that soothe you without the help of a partner, she adds, is just as key.

Having an SO around can also benefit your sleep health in some slightly more unexpected ways. For instance, they can be there to help hold you accountable when you’re trying to cut back on using your phone in bed, or stick to an earlier bedtime. “A benefit of having a sleeping partner is that they often are the first to notice sleep difficulties (e.g., snoring related to sleep apnea),” Dautovich says, so the two of you can both provide support and promote healthy sleep behaviors for one another. It’s certainly worth the try, right? Clearly the sleep of your future self depends on it.

Cognitive Behavioral Therapy for Insomnia | Patient Advice | US News

See Author Article Here
By Michael O. Schroeder

Many, many people have difficulty falling asleep or staying asleep. Research generally suggests that around a third of Americans have insomnia at any given time, and about 1 in 10 have chronic insomnia, lasting three months or longer.

Not getting adequate rest can affect mood (while depression can also contribute to insomnia), undermine motivation, increase irritability and make it difficult to just get through the day. “For those who take care of small children or have a lot of family and work responsibilities to balance,” the National Sleep Foundation notes, “insomnia can make these tasks feel even more overwhelming when you are tired.”

Often people try over-the-counter sleep aids or nothing at all – just thinking they have to live with it – rather than seeking help from a professional.

It’s common for patients who see Dr. Rafael Pelayo to have been struggling with insomnia for years. It’s “not unusual for me to see someone with decades of poor sleep,” says the sleep specialist and clinical professor of psychiatry and behavioral sciences at the Stanford Center for Sleep Sciences and Medicine. But even those who’ve had chronic insomnia for years can still get better when the insomnia is addressed correctly, he says.

And although the treatment isn’t new, there’s growing recognition of a tailored therapeutic approach used to change a person’s thinking and behavior that has lasting benefits for the majority who undergo it: cognitive behavioral therapy for insomnia. Most who undergo four to eight sessions of CBT-I experience a significant reduction in their symptoms – namely the time required to fall asleep, the amount of time spent awake or both – notes Michael Perlis, director of the behavioral sleep medicine program in the department of psychiatry at the University of Pennsylvania.

While experts note that sleep medication, prescribed in combination with CBT-I or alone, is another option, CBT-I’s “durable results” – generally continuing after a person stops the therapy – make it an optimal approach. “It is recommended as the first line treatment,” Perlis says.

It’s not just mental health professionals advocating for the treatment either, but the medical establishment. The American College of Physicians led the way in guidelines published in 2016ACP recommends that all adult patients receive cognitive behavioral therapy for insomnia (CBT-I) as the initial treatment for chronic insomnia disorder,” the medical society asserted.

Perlis explains that CBT-I has four components: sleep restriction, stimulus control, sleep hygiene and cognitive therapy. Often it’s counterintuitive, too, like with sleep restriction. One might think that if you can’t sleep you should stay in bed for longer. But actually experts say it’s important to match your sleep opportunity, or how long you’re in bed, with how long you’re able to sleep, and then gradually work on increasing sleep time. “It doesn’t aim to restrict actual sleep time but rather to initially restrict the time spent in bed,” Stanford Health Care’s website explains, regarding the sleep restriction component of CBT-I. “Subsequent steps consist of gradually increasing the time spent in bed.”

While some people may feel they’re familiar with certain concepts and components of CBT-I, like sleep hygiene (being mindful of how factors like substance use, such as caffeine and alcohol consumption, can affect sleep), implementing it correctly tends to be more complex and involved. Experts say that’s why it’s key to see a professional experienced in CBT-I for effective treatment. “Those that try to do CBT-I to themselves are likely to not be successful,” Perlis says. “But worse is that they will believe that they’ve been there, done that, and so the likelihood of seeking out professionally administered CBT-I goes way down.”

One significant limitation with CBT-I, however, is access. “Finding a therapist is not easy,” Perlis says. “CBT-I is not yet available in every state or every city.” However, there are some directories – he recommends a couple through Perelman School of Medicine at Pennsylvania University and the Society of Behavioral Sleep Medicine, respectively – that can be used to find therapists who do CBT-I.

Pelayo points out that for those who aren’t able to see a professional who does CBT-I in their area, there are online CBT-I programs that allow a person to engage in the therapy from home virtually. “I’m OK with somebody doing it online if they want to – if they live far away,” Pelayo says. “And if they got better, I’m happy for them, of course. But if they don’t get better, if they’ve done the online thing, then we actually want them to have a face-to-face.”

He says patients typically pay cash for online CBT-I.

Insurance coverage of in-person cognitive behavioral therapy for insomnia varies. So it’s important to check in advance to determine that. As the therapy is more widely used, and given the support for its effectiveness, clinicians are hopeful insurance coverage of CBT-I will improve, but it’s not universal today.

Pelayo says some individuals, like those with profound autism or schizophrenia, aren’t able to participate in CBT-I. Others, he says, either prefer not to undergo therapy, or aren’t able or don’t want to make the time commitment.

Certainly, CBT-I has advantages – notably the lasting benefits, after a person has stopped therapy; that differs from medication that provides benefit while on it. But experts say, first and foremost, it’s key that those with chronic insomnia generally seek help to get a better idea of what’s behind it and explore treatment options.

In some cases, it may be a medical or mental health issue that’s causing sleep problems or making things worse, and cognitive therapy may still be useful (like with depression). But having a fuller picture, is critical. For example, often thyroid disease can contribute to sleep woes and is overlooked, Pelayo says. Or a person may have another disorder like sleep apnea, along with insomnia, that needs to be addressed as well, he says.

None of that will be rectified through an online search in your pajamas (though you might find a sleep specialist that way).

“I tell all my patients that if they don’t wake up feeling refreshed, something is wrong,” Pelayo says. When sleep problems persist, experts say, instead of trying to put them out of your waking mind – seek help to get them addressed.

Why People With A History Of Bad Relationships Don’t Sleep Well

See Author Article Here
By Kelly Gonsalvez

Anyone who has ever slept next to a partner knows being part of a unit can affect how well you sleep—from dealing with the other person’s weird tossing and turning all night to battling for your fair share of the blanket to trying to get some shut-eye when you’re still halfway through a fight with the person lying next to you and you can’t stop thinking about it.

Past research has shown your relationship can affect your sleep, but a new study published in the Personal Relationships journal has now found an even deeper connection between your love life and sleep: Apparently having a history of stressful relationships may make you more likely to have poorer sleep quality.

Researchers analyzed existing data that had been collected on over 260 people born in the mid-1970s regularly from the time they were born until mid-adulthood. These participants were asked questions about their lives periodically, including being surveyed and interviewed about their recent romantic relationships, experiences with stress, and sleep quality. Analyzing these people’s responses between ages 23 and 37, the researchers discovered a trend: People who’d had better relationships during their early adult years dealt with fewer and less disruptive stressful life experiences at age 32, and that led to having better sleep quality at age 37. That was true regardless of depression status, gender, ethnicity, income, education, and even how much stress people currently had at age 37.

In other words, having a history of good relationships as a young adult—that is, stable long-term relationships where there’s mutual care, trust, emotional closeness, and sensitivity to each other’s needs and where conflicts are resolved in a healthy and satisfying way—tended to lead to less stressful experiences throughout adulthood, which in turn led to better sleep over time.

It’s understandable why stressful life experiences (like job changes, health issues, legal battles, and interpersonal conflicts) would take their toll on a person’s sleep quality; a lot of past research has shown that having a lot of stress can seriously disrupt your sleep. But why might having a better love life lead to having fewer of these types of seemingly unrelated tough life events, or at least having them be less stressful?

“One explanation is that people who possess the interpersonal competencies necessary to maintain relationships marked by mutual caring, trust, conflict resolution, and other positive characteristics are also more likely to have other traits that may mitigate their exposure to and reduce the severity of those stressors when they occur,” the researchers write in the paper. “For instance, people who score high in romantic relationship effectiveness may be more likely to demonstrate caring and responsiveness in other types of relationships (e.g., with family or co-workers), which might reduce exposure to conflict. Moreover, when stressful events due to uncontrollable sources are encountered (e.g., unemployment, death of a family member), people high in relationship effectiveness may also be more likely to possess intrapersonal and interpersonal resources, allowing them to cope better with the stressful life event and reduce its severity.”

So people who are good at romantic love are probably good at dealing with people in other parts of their life, and those skills and emotional experiences set them up to either avoid stressful occasions or deal with them well when they occur.

“Cues of social belongingness and emotional security can facilitate a sense of protection that down-regulates stress reactivity and promotes better sleep,” the researchers explain. “Given that romantic relationships are an especially potent source of social belongingness and emotional security in adulthood, one’s experiences, tendencies, and engagement in his or her romantic relationships should have a particularly strong impact on sleep patterns.”

This is all pretty hard news to hear for anyone who feels like they’ve had a pretty unlucky love life thus far. But don’t worry: The point here isn’t that if romance isn’t the easiest for you, you’re doomed to a life of stress and bad sleep. Rather, this study simply reinforces one of the most important benefits of being in a relationship: being able to learn about how to communicate better, navigate conflicts, take care of another person, and take care of yourself. Relationships are far less about validating your worth as much as they are about learning how to become a better human being.

The good news? You can totally do that without a partner, too. Romantic relationships happen to be a great place to learn those lessons, but so are so many other parts of our social lives—our family relationships, our friendships, our professional connections, and more.

If your sleep and mental health are important to you, then your social relationships should be too. Interfacing with other people is pivotal not only to learning how to deal with stress and conflict but also to having a support system in place during all those bad times. That stability seems to be the real key to being able to have a secure, peaceful night’s sleep over time.

What Is Chronic Insomnia And How Is It Treated?

See Healthline Article Here


Insomnia is a common sleep disorder in which you may have trouble falling asleep, staying asleep, or both. A third of Americans report that they don’t get the recommended amount of sleep every night, which is at least seven hours.

Periodically having trouble sleeping, also known as acute insomnia, is common. Acute insomnia lasts for a few days or weeks and often occurs during times of stress or life changes.

Have trouble getting to sleep or staying asleep more than three nights a week for three months or more is considered chronic insomnia. This is also known as chronic insomnia disorder.

Types of chronic insomnia

There are two main types of chronic insomnia: primary and secondary.

Primary insomnia isn’t due to other medical conditions or medications and is poorly understood by scientists. Specialized MRI scans are being used to study this condition. Primary insomnia may be related to changes in levels of certain brain chemicals, but research is ongoing.

Secondary insomnia is caused by other conditions or situations. This means that it’s a symptom that goes along with some medical issues, such as emotional stress, trauma, and ongoing health problems; certain lifestyle patterns; or taking certain drugs and medications.

Symptoms of chronic insomnia

Chronic insomnia can cause symptoms at night as well as during the day and can interfere with your ability to go on with your daily tasks.

Symptoms may include:

  • trouble falling asleep
  • waking up throughout the night
  • trouble staying asleep or trouble returning to sleep
  • waking up too early
  • daytime sleepiness or grogginess
  • not feeling rested after a night’s sleep
  • irritability
  • mood changes, such as feeling depressed
  • difficulty concentrating
  • problems with memory
  • increase in mistakes and accidents
Causes of chronic insomnia

There are many things that can cause chronic insomnia, but it’s often linked to an underlying medical condition. Certain medications and stimulants can cause chronic insomnia, along with lifestyle patterns.

Medical conditions

Chronic insomnia can be caused by a number of long-term medical conditions, including:

Medications and stimulants

For some people, certain medications and stimulants may cause chronic insomnia. These include:

  • alcohol
  • antidepressants
  • beta-blockers
  • caffeine
  • chemotherapy drugs
  • cold and allergy medications containing pseudoephedrine
  • diuretics
  • illicit drugs, such as cocaine and other stimulants
  • nicotine
  • stimulant laxatives

Lifestyle patterns

Certain lifestyle patterns may lead to chronic insomnia. These include:

  • rotating shift work
  • frequent travel across multiple time zones, leading to jet lag
  • physical inactivity
  • frequent daytime napping
  • lack of routine for waking and sleeping
  • poor sleeping environment
Treatment of chronic insomnia

A number of at-home and professional treatment options are available for chronic insomnia. Treatment will depend on the cause of your insomnia and may involve medication or therapy to address an underlying condition.

Along with treating any existing conditions, your doctor may recommend one or a combination of treatment options for chronic insomnia.

Cognitive behavioral therapy (CBT)

Research has shown CBT to be as effective, or more effective, than sleep medications in treating chronic insomnia. It involves educating you on sleep and better sleep habits, while teaching you to change the beliefs and behaviors that interfere with your ability to sleep.

Some of the strategies of CBT that are specifically focused on insomnia, known as CBT-I, include the following:

Cognitive techniques

Using journaling to write down worries or concerns before going to bed may help keep a person from actively attempting to work them out while also trying to sleep.

Stimulus control

This entails altering behaviors that condition your mind to fight sleep. Setting a sleep and wake time routine is part this strategy.

Other examples are using your bed only for sleep and sex, and leaving your bedroom if you’re unable to fall asleep within a set number of minutes.

Sleep restriction

This therapy involves limiting the amount of time you spend in bed, including avoiding naps. The goal is to deprive you of enough sleep so that you’re tired at bedtime. Your time in bed is gradually increased as your sleep improves.

Relaxation techniques

Breathing exercises, yoga, guided meditation, and other techniques are used to reduce muscle tension and control your breathing and heart rate so that you’re able to relax.

Paradoxical intention

This strategy involves focusing on staying awake in bed instead of expecting to fall asleep. It helps reduce worry and anxiety over being able to fall asleep. It’s most effective in treating learned insomnia.


There are a number of prescription medications and over-the-counter (OTC) sleep aids that may help you get to sleep or remain asleep.

While effective, doctors don’t typically recommend using sleeping pills long term because of the side effects, which can include daytime sleepiness, forgetfulness, sleepwalking, balance problems, and falling. Certain classes of sleeping pills are also habit-forming.

Some of the prescription medications that are approved for treating insomnia include:

  • zolpidem (Ambien)
  • eszopiclone (Lunesta)
  • zaleplon (Sonata)
  • doxepin (Silenor)
  • ramelteon (Rozerem)
  • suvorexant (Belsomra)
  • temazepam (Restoril)

OTC sleep aid options may include:

Always speak to your doctor before taking an OTC sleep aid, including natural remedies, such as melatonin and valerian root. Just like prescription drugs, OTC and natural sleep aids can cause unwanted side effects and interfere with other medications.

Cure for chronic insomnia

If your chronic insomnia is caused by an underlying medical condition, such as acid reflux or pain, treating the condition may cure your insomnia.

Chronic health conditions that cause insomnia can be managed with changes in treatment, in turn managing or preventing insomnia. Talk to your doctor about changing medications or treatment plans if a drug you’re taking is causing insomnia.

Home remedies for chronic insomnia

There are several things that you can do at home to treat or prevent chronic insomnia. One important option for treatment is known as sleep hygiene. This calls for changes in patterns of behavior to help improve your ability to fall asleep and stay asleep.

Try the following tips:

  • Avoid caffeine, especially later in the day.
  • Avoid alcohol use and smoking cigarettes before bed.
  • Engage in regular physical activity.
  • Don’t take naps.
  • Don’t eat large meals in the evening.
  • Go to bed and get up at the same time every day, even on days off.
  • Avoid using computers, smartphones, TV, or other technological devices an hour before bedtime.
  • Keep your bedroom dark or use a sleep mask.
  • Keep your bedroom a comfortable temperature.
  • Make sure your sleep surface is comfortable.
Outlook for chronic insomnia

Chronic insomnia can be effectively treated using a combination of behavioral therapies and by making a few lifestyle changes to help improve your sleep. If you’re having trouble sleeping and it’s interfering with your quality of life, talk to your doctor.

Insomnia Series: Sleep Deprivation Was More Powerful Than Antidepressants For Me

See Vice Article Here
By Jesse Noakes

On a Saturday night last year, not long after the death of my grandmother, I went to her house to try a little experiment. I’d been depressed again for more than a week. I felt stodgy and frozen, woozy with lethargy, and at the same time prickling with a static sense of anxiety that became especially charged around other people.

I woke just after 2 am on a sofa bed in her guest room. The house was icy cold and lonely. I switched on the heater in her living room, made myself coffee, and sat down at her heavy dining table with my laptop. Five hours, another coffee, and a couple of thousand words later, the sun was up and I drove to the gym. By the time I met my aunt at a cafe near the beach a couple of hours later, I felt fresh and clear in the sunshine. I could lock eyes and smile with the lovely woman at the table next to us and my conversation with my aunt was fluid and enthusiastic. I was feeling good again.

About a decade ago, I figured out that if I stayed up all or most of the night, I’d usually feel a lot better in the morning. For years, I’d been managing major depressive disorder—I was ill at ease with myself, awkward in conversation, and clumsy and self-conscious in my body. My long-term psychiatrist thought I could be bipolar, and put me on a high dose of the mood stabilizer lithium, to no noticeable effect. I spent the remainder of my early 20s playing the pharmaceutical lottery, to no avail.

It was only recently that I started experimenting with sleep deprivation again, after I learned that others had the same idea. In fact, since the early 1970s, when a young German psychiatrist called Bernhard Pflug noticed that some of his patients felt better after a night without sleep, there has been a tiny but growing school of research studying the potential of sleep deprivation as a fast-acting antidepressant.

In a 2015 study that compared the efficacy of exercise versus sleep deprivation, 75 depressed patients in Copenhagen who were treated with three all-nighters in a week had almost double the remission rate compared to another group who used daily exercise. Seven months after their treatment, 62 percent of the sleep-deprived no longer met the criteria for clinical depression. A 2017 meta-analysis looked at 66 studies of sleep deprivation and its effects on depression published in the past three decades, and found that 50 percent of patients had a clinically significant response to the treatment.

What was remarkable about this research was the speed with which the transformation happened. Where antidepressant meds typically take several weeks to kick in, with these sleep deprivation studies, participants saw an improvement in their mood (at least temporarily) overnight. This represents a significant boon for anyone stuck in the airless swamp of depression, but, according to a small 2014 pilot study in South Carolina, it could be especially potent for those experiencing suicidal thoughts or ideation. That research found that a single night of sleep deprivation led to a 63 percent mean reduction on the Columbia Suicide Severity Rating Scale.

“Even in the ‘70s it was clear—when you’ve seen a severely melancholic patient turn into somebody who can actually talk to you and even smile just by staying awake all night, you think it’s absolutely a miracle,” says Anna Wirz-Justice, professor emeritus at the Centre for Chronobiology in Basel, Switzerland, who first became interested in its therapeutic potential shortly after the first publication of Pflug’s remarkable responses.

It seems almost too good to be true—and in some ways, it is. For the vast majority of patients, as many as 95 percent, the effects wear off as soon as they have a decent sleep. As a psychiatrist once put it to Wirz-Justice, “why offer people paradise just to take it away again?”

Several people with depression I’ve spoken to recently have said that non-clinical, DIY sleep deprivation gives them relief, but with cautious enthusiasm. “It’s notable, but nothing life-changing,” David, a 33-year-old from Quebec, tells me. He usually prefers to “sleep a couple hours and have a decent next day with a slightly less noticeable mood boost,” rather than staying up all night but suffer headaches as a result. “But it doesn’t sustain itself for me.”

The cognitive, behavioral, and physical health deficits of sleep deprivation are well-established, and we all recognize them. But the impairments to motor control, memory, and higher cognitive function that the majority report after little or no sleep are also characteristic of depression. Therefore, for depressives, the short-term antidepressant effects of sleep deprivation counter-balance and may outweigh its negative cognitive effects.

More from Tonic:

In recent years, most clinical trials have added adjunctive therapies to build on the immediate antidepressant effect of the sleep deprivation. Light therapy, a long-standing treatment for seasonal affective disorder in which patients sit for half an hour in front of a very bright light box, is often used for several mornings after the initial all-nighter. Another method is sleep phase advance (SPA), which begins with early bedtime the night after sleep deprivation and gradually returns the patient’s sleep pattern to normal within a few nights.

It’s also common for patients to be on a longer course of antidepressants like fluoxetine (Prozac), or a mood stabilizer such as lithium, to cement the improvement after the immediate treatment is completed. The combination of sleep deprivation, light therapy, and either SPA or ongoing medication is referred to as ‘triple chronotherapy,’ Wirz-Justice explains. “The idea is you use everything you’ve got to get out and keep out of depression in four days. Isn’t that something to aim for? Why doesn’t it catch on?”

I can think of several reasons, and the main one is it’s just really hard. When I’m depressed, I sleep a lot. A lot of depressed people do. I spent much of my 20s lying in bed, staring at the wall with the blinds down. Getting up at all is an effort, let alone staying up all night. Recognizing this, some clinicians use a partial sleep deprivation where patients sleep the first part of the night and are woken at 2 am—it’s an easier sell, and works almost as well.

This is the protocol I’ve adopted. Studies have found little difference between a full all-nighter and grabbing a couple of hours’ rest, says Francesco Benedetti, head of the psychiatry and clinical psychobiology unit at San Raffaele Hospital in Milan and one of the leading researchers in the field. “[Partial sleep deprivation late in the night was followed by response rates similar to those obtained after total sleep deprivation…but the issues of efficacy, timing and stress are yet debated,” he says.

As for doing it at home, as I’ve done recently? “If you’re knowledgeable about it you can find the information and follow the protocol, but to do it on your own I think is very tough,” says David Veale, consultant psychiatrist at the Priory Hospital in North London, where he is running the UK’s first clinical trial of sleep deprivation for depression. He says it’s more difficult than dangerous.“ Perhaps the only potential risk is for people with bipolar disorder who may become manic during the program—so I wouldn’t recommend it if you’re on your own…though it’s probably no different from other medications. If you’ve ever met somebody having a manic episode, it isn’t difficult to tell,” Veale adds. Mania is typically characterized by grandiosity, racing thoughts, irritability, sleeplessness and heightened impulsivity.

It’s not only personally counterintuitive to stay up all night when you’re depressed, it also goes against every prevailing cultural norm. The premium importance of sleep is reinforced everywhere, and with good reason. “If you don’t have depression and you stay up all night, you feel pretty crap, don’t you?” Veale says. Patients with serious clinical depression may respond differently, though. “Depressed patients will have some tiredness, of course, but if they’re responding then they’re also recovering from their depression.”

Part of the reason for this apparent paradox is the neurotransmitter dopamine. A study in the Journal of Neuroscience suggested that a night of sleep deprivation causes increased dopamine production, which “correlated with increases in fatigue and with deterioration in cognitive performance.” However, dopamine also functions as the brain’s reward mechanism, and its subjective effect is often an increase in mood, short-term energy and feelings of positivity. As Veale explains, patients may be fatigued but they’ll also be feeling better in spite of their tiredness.

Another neurochemical that increases in the sleep-deprived brain, adenosine, has been shown to correlate with resilience to depression and its mind-numbing effects while also mediating the effects of an all-nighter, and it seems to be central to the action of other depression treatments, like ketamine. In fact, according to a paper by Benedetti, sleep deprivation affects “almost all the neurotransmitters targeted by antidepressant drugs.”

However, the precise mechanism of how sleep deprivation works for depressed people remains largely mysterious. Both Benedetti and Wirz-Justice note that similar confusion surrounds our understanding of most antidepressant meds. “Maybe you just have to shake up the neurotransmitters,” Wirz-Justice says an old mentor told her. Especially with something as fundamental to our biological and circadian rhythms as sleep, the idea of resetting the clock, so to speak, is a powerful one.

Yet it’s not something that’s caught the popular, or commercial, imagination, Veale says. The fact you can’t patent “not sleeping” might have something to do with it. “How do you do double-blind placebo-controlled trials for something like staying awake all night?” Wirz-Justice says. “Who pays for it? How do you calculate the costs? It’s so different from a pill.”

If I’d known a decade ago that there was clinical evidence for sleep deprivation, I’d have been less likely to dismiss my own experience as just a curiosity, and kept at it. Instead, for years I largely forgot about it—until my uncle emailed a link about Veale’s study, and I decided there might be something to it after all.

One night last week, around 2am, when my emails finally crossed the incoherency threshold, I flipped my Macbook closed and left the couch for bed. I woke before my 5 am alarm with the birds through the window, to hit the gym and beach as usual. By the time I was happily ensconced in the cafe with free refills of Ethiopian coffee, I felt more alert and in sync than I had all week.

Three days later and I’m still in the clear. I’ve felt consistently lucid, engaged, and energized. Last night, after a long Saturday in the Australian sun, I fell asleep at half past nine still in my tennis clothes. It’s not necessary, or possible, to stay up all night every night. Instead, it can act as a jump-start—after that, it’s over to me to channel and maintain my energy through exercise, people, and things that matter.

Like Veale, Wirz-Justice acknowledges the close link between circadian rhythms and the bipolar. “The switch into mania is nearly always accompanied by a lack of sleep, and with medically prescribed sleep deprivation you can switch someone out of depression. So it’s very deeply rooted with bipolarity.” I explained to her that I experience life itself as a fairly up-and-down affair, to which her response was tart: “Yes, well, I prefer the ups.”

Insomnia Series: 8 Weird Facts About Sleep Science Learned In 2019 Alone

See Author Article Here
By JR Thorpe

Maybe it’s because 2018 was a hell of a year and we all want to spend most of 2019 in sweet, sweet slumber, but there was a lot of research published in January this year about sleep. Like, a lot of research. These new findings about sleep covered a lot of ground, from the neural patterns of the sleeping brain to the genetics of early risers and the tie between sleep and health — and it’s changing the way we think about rest. If you’ve always been curious about how sleep shapes our lives, this crop of research shows that it’s hugely influential in unprecedented ways.

Sleep involves many moving parts. There are the hormonal signals issued by your brain that indicate when you should fall asleep or wake up; the circadian rhythms of each cell in your body, which dictate your sleep-wake cycle over a 24-hour period; the four separate stages of sleep, including REM or rapid eye movement sleep, which occur multiple times over the course of a night’s slumber; and other factors, including genetics, stress and environment, that influence how your sleep actually progresses. It’s possible to examine sleep from many different angles — and, as these studies show, science is still learning a lot of mind-blowing things about our bodies and minds when we drop off to sleep every night. Here are eight brand-new facts about sleep.

1There’s A Single Gene Behind Our Need To Sleep When Sick


Many of us experience an increased need for sleep when we’re sick, which makes sense; avoiding over-exertion while the body fights off infection or illness seems logical. Researchers from the University of Pennsylvania found a single gene behind the urge to sleep while sick in fruit flies. They published their findings in Science, and it’s a big deal; the gene itself, which they called nemuri (the Japanese word for sleep), is one of the most tangible bits of concrete proof that sleep and the immune system are biologically connected.

When the nemuri gene was removed from the fruit flies, they stopped feeling the need to sleep when ill — but when it acted normally, the fruit flies slept, and survived being sick in great numbers. If the same thing applies in humans, nemuri is what makes us sleep when we’re sick — and keeps us alive while our immune system fights off threats.

2If You Have Sleep Apnea, You Struggle To Recall Your Memories

Sleep apnea, the condition where breathing stops temporarily during sleep, is pretty common; the National Sleep Association has estimated that around 18 million American adults experience it. A new study revealed that having sleep apnea has an unexpected affect on the brain: it impacts autobiographical memory. The research, published in the Journal of the International Neuropsychological Society, focused onobstructive sleep apnea (OSA), the most common type of the condition, where breathing stops because airways become too narrow for air to pass through. And researchers found that people with OSA had difficulty recalling personal memories.

The people with OSA over-generalized their childhood memories, and while they remembered incidents and important events, were much less likely than people without OSA to remember details, like names or dates. The worse their memories, the more likely they were to have symptoms of depression. Good autobiographical memory is important for our mental health, and it seems that sleep apnea, and its impact on long-term memories, can seriously compromise mood.

3You *Can* Actually Learn Foreign Vocabulary In Your Sleep


The idea of learning in your sleep has been around for ages, but new research in January showed that it’s more than a fable. It won’t exactly mean you wake up fluent, though. The study, by scientists at the University of Bern, found that learning new vocab in your sleep can depend on when it’s played to you.

In a deep sleep state, brain cells go through slow waves; they’re active for a brief time, then lull into inactivity. The Bern scientists played pairs of words — one actual German word, one nonsense word — to German-speaking people at various stages of sleep. If the pairs were repeated numerous times during an “up” state, when the brain was active, the people were more likely to match the words into pairs when they were awake. It’s a sign that the brain can sort and try and understand new words even while we’re asleep. Don’t rely on it instead of your Duolingo, though.

4We Still “Hear” During Some Parts Of Our Sleep Cycle

According to research published in Nature in January, sleeping people aren’t always as dead to the world as they appear. It turns out that, when we’re asleep, we still listen to the world around us with a small portion of our brains, keeping track of noises that might be relevant. “Sleepers enter a ‘standby mode’ in which they continue tracking relevant signals, finely balancing the need to stay inward for memory consolidation with the ability to rapidly awake when necessary,” explained the researchers.

They tested this by looking at the electrical brain signals of sleeping people while surrounded by various kinds of noises. When they weren’t in deep sleep, their brains ‘spiked’ whenever they heard noises that carried meaning, like familiar voices, while ignoring other noises. When they entered properly deep, non-dreaming sleep, though, the effects vanished. If you’re just dropping off to sleep or waking up up and think you’re ‘hearing’ what’s happening around you, you’re not wrong; your brain is still listening, to make sure you can wake up and deal with a threat if necessary.

5Losing Sleep Due To Stress Changes The Cells In Your Brain


REM sleep is the period of sleep where we dream, and a January study in PNASreveals that stress directly impacts how much REM sleep we have. According to the research in mice, mild daily stress increases the mice’s amount of REM sleep before it impacts any other sleep stage. Abnormalities in REM sleep are closely tied to depression and mood disorders, so stress might be affecting mood via our sleep. That wasn’t the end of the story, though.

The researchers also found that when stress impacted REM sleep, the brain also physically changed its structure, particularly in the hippocampus. Various cells died, while others were grown — and that’s important, because the hippocampus is a big part of our response to stress and how we deal with it. It seems that in mice, increased REM sleep in response to stress also makes the brain change its shape, to deal with the stress it might encounter while it’s awake.

6Sleep Deprivation Increases Your Risk Of Alzheimer’s And Heart Issues

New science is constantly appearing about the impacts of sleep deprivation, and two new studies in January added to that picture. One, from the Washington School of Medicine, found that sleep deprivation in both mice and people increases the amount of a particular protein, tau, which is found in clumps in the brain of people with Alzheimer’s. The less sleep you get, the more your brain accumulates this protein that can make it vulnerable to long-term issues like Alzheimer’s.

The other study, from the American College of Cardiology, focussed on another area of human health: the heart. They tracked the sleep of over 3,000 Spanish adults and found that those who slept under six hours a night regularly were up to 27 percent more likely to have plaque build-up inside their arteries than those who got an average of eight or nine hours. Plaque build-up narrows the arteries, and is associated with cardiovascular issues and heart attacks.

7Your Neurons Do Different Things In Different Sleep Stages


What happens in your brain when you sleep? Quite a lot, as it turns out. A study published in Nature found that when we sleep, our neurons fire in many different ways, differing according to our sleep stage and where in the brain they’re located. During REM sleep, the hippocampus neurons don’t fire very much, while those in the frontal cortex show a lot of activity. In non-REM sleep, meanwhile, neural firing – the amount of electrical activity — evened out in both areas, and the communication between neurons slowed down.

What does this mean? Well, understanding brain activity during sleep is a big deal, because our brains do a lot of work while we snooze. Sleep is crucial for the consolidation of our memories, cleans toxic substances out of our brains, and helps cells refresh themselves for the day ahead. It turns out that the neural cells in our brains are doing more complicated work than we thought — and that could help us understand how mechanisms like memory and learning during sleep actually work.

8There Are 351 Bits Of Genetics Associated With Being A Morning Person

Enjoy waking up at the crack of dawn? You’re an early bird — and research indicates that the tendency to wake and sleep early is largely determined by genetics. Research published in January gave us more evidence for that fact, by expanding the amount of genetic loci, or genes in specific locations on chromosomes, associated with early-bird tendencies. And they expanded it a lot — from 24 genetic loci to a whopping 351.

The research, published in Nature Communications, found that these 351 distinct genetic loci are all associated with circadian rhythms that naturally tend towards early-to-bed-early-to-rise sleeping. It was a very big study, using data from 85,760 people, and found that these genetic signals make a significant difference. The subjects with the most early-rise genetic loci woke up 25 minutes earlier, on average, than the people with the fewest loci. If you want to change your early-bird tendencies, this research shows, it might be harder than you think; it could be encoded in your genes.

Sleep is more complicated than it appears. As 2019 goes on, we’ll probably experience more wild and weird revelations about how it works — and may end the year with our minds totally blown. One thing’s universally true, though: sleep is greatand very useful for our health. Get more if you can.
