What do we know about the usefulness of complementary approaches for sleep disorders?

  • Relaxation techniques can be helpful for insomnia.
  • Melatonin supplements may be helpful for sleep problems caused by shift work or jet lag. Melatonin may also be helpful for people with insomnia, but its effect is small.
  • The evidence for other complementary approaches is either inconsistent or too limited to draw conclusions about whether they are helpful for sleep disorders.

What do we know about the safety of complementary approaches for sleep disorders?

  • Relaxation techniques are generally considered safe.
  • Melatonin appears to be relatively safe for short-term use, but its long-term safety has not been established.
  • There are serious safety concerns about kava products (which have been linked to severe liver damage) and L-tryptophan supplements (which may be associated with a potentially serious disorder called eosinophilia-myalgia syndrome).
  • If you use a complementary approach for a sleep problem, tell your health care providers. They can do a better job caring for you if they know what you’re using.

What Are Sleep Disorders and How Important Are They?

There are more than 80 different sleep disorders. This fact sheet focuses on insomnia—difficulty falling asleep or difficulty staying asleep. Insomnia is one of the most common sleep disorders.

More information

Chronic, long-term sleep disorders affect millions of Americans each year. These disorders and the sleep deprivation they cause can interfere with work, driving, social activities, and overall quality of life, and can have serious health implications. Sleep disorders account for an estimated $16 billion in medical costs each year, plus indirect costs due to missed days of work, decreased productivity, and other factors.

To learn more about sleep disorders, visit the National Heart, Lung, and Blood Institute (NHLBI) Web site.

Is It a Sleep Disorder or Not Enough Sleep?

Some people who feel tired during the day have a true sleep disorder, but for others, the real problem is not allowing enough time for sleep. Adults need at least 7 to 8 hours of sleep each night to be well rested, but the average adult sleeps for less than 7 hours a night.

More information

Sleep is a basic human need, like eating, drinking, and breathing, and is vital to good health and well-being. Shortchanging yourself on sleep slows your thinking and reaction time, makes you irritable, and increases your risk of injury. It may even decrease your resistance to infections, increase your risk of obesity, and increase your risk of heart disease.

What the Science Says About Complementary Health Approaches and Insomnia

Research has produced promising results for some complementary health approaches for insomnia, such as relaxation techniques. However, evidence of effectiveness is still limited for most products and practices, and safety concerns have been raised about a few.

Mind and Body Practices

  • There is evidence that relaxation techniques can be effective in treating chronic insomnia.

    More information

    • Progressive relaxation may help people with insomnia and nighttime anxiety.
    • Music-assisted relaxation may be moderately beneficial in improving sleep quality in people with sleep problems, but the number of studies has been small.
    • Various forms of relaxation are sometimes combined with components of cognitive-behavioral therapy (such as sleep restriction and stimulus control), with good results.
    • Using relaxation techniques before bedtime can be part of a strategy to improve sleep habits that also includes other steps, such as maintaining a consistent sleep schedule; avoiding caffeine, alcohol, heavy meals, and strenuous exercise too close to bedtime; and sleeping in a quiet, cool, dark room.
    • Relaxation techniques are generally safe. However, rare side effects have been reported in people with serious physical or mental health conditions. If you have a serious underlying health problem, it would be a good idea to consult your health care provider before using relaxation techniques.
  • In a preliminary study, mindfulness-based stress reduction, a type of meditation, was as effective as a prescription drug in a small group of people with insomnia.

    More information

    • Several other studies have also reported that mindfulness-based stress reduction improved sleep, but the people who participated in these studies had other health problems, such as cancer.
  • Preliminary studies in postmenopausal women and women with osteoarthritis suggest that yoga may be helpful for insomnia.
  • Some practitioners who treat insomnia have reported that hypnotherapy enhanced the effectiveness of cognitive-behavioral therapy and relaxation techniques in their patients, but very little rigorous research has been conducted on the use of hypnotherapy for insomnia.
  • A small 2012 study on massage therapy showed promising results for insomnia in postmenopausal women. However, conclusions cannot be reached on the basis of a single study.
  • Most of the studies that have evaluated acupuncture for insomnia have been of poor scientific quality. The current evidence is not rigorous enough to show whether acupuncture is helpful for insomnia.

Dietary Supplements

Melatonin and Related Supplements

  • Melatonin may help with jet lag and sleep problems related to shift work.
  • A 2013 evaluation of the results of 19 studies concluded that melatonin may help people with insomnia fall asleep faster, sleep longer, and sleep better, but the effect of melatonin is small compared to that of other treatments for insomnia.

    More information

    • Studies of melatonin in children with sleep problems suggest that it may be helpful, both in generally healthy children and in those with conditions such as autism or attention-deficit hyperactivity disorder. However, both the number of studies and the number of children who participated in the studies are small, and all of the studies tested melatonin only for short periods of time.
    • Melatonin supplements appear to be relatively safe for short-term use, although the use of melatonin was linked to bad moods in elderly people (most of whom had dementia) in one study.
    • The long-term safety of melatonin supplements has not been established.
  • Dietary supplements containing substances that can be changed into melatonin in the body—L-tryptophan and 5-hydroxytryptophan (5-HTP)—have been researched as sleep aids.

    More information

    • Studies of L-tryptophan supplements as an insomnia treatment have had inconsistent results, and the effects of 5-HTP supplements on insomnia have not been established.
    • The use of L-tryptophan supplements may be linked to eosinophilia-myalgia syndrome (EMS), a complex, potentially fatal disorder with multiple symptoms including severe muscle pain. It is uncertain whether the risk of EMS associated with L-tryptophan supplements is due to impurities in L-tryptophan preparations or to L-tryptophan itself.

Herbs

  • Although chamomile has traditionally been used for insomnia, often in the form of a tea, there is no conclusive evidence from clinical trials showing whether it is helpful. Some people, especially those who are allergic to ragweed or related plants, may have allergic reactions to chamomile.
  • Although kava is said to have sedative properties, very little research has been conducted on whether this herb is helpful for insomnia. More importantly, kava supplements have been linked to a risk of severe liver damage.
  • Clinical trials of valerian (another herb said to have sedative properties) have had inconsistent results, and its value for insomnia has not been demonstrated. Although few people have reported negative side effects from valerian, it is uncertain whether this herb is safe for long-term use.
  • Some “sleep formula” dietary supplements combine valerian with other herbs such as hops, lemon balm, passionflower, and kava or other ingredients such as melatonin and 5-HTP. There is little evidence on these preparations from studies in people.

For more information on dietary supplements.

Other Complementary Health Approaches

  • Aromatherapy is the therapeutic use of essential oils from plants. It is uncertain whether aromatherapy is helpful for treating insomnia because little rigorous research has been done on this topic.
  • A 2010 systematic review concluded that current evidence does not demonstrate significant effects of homeopathic medicines for insomnia.

NCCIH Research on Sleep Disorders

NCCIH funds research on complementary health approaches for sleep disorders.

More information

Recent projects include studies on:

  • How mindfulness meditation training may affect the amount and quality of sleep
  • The effect of blue-white light on sleep disorders in patients with Alzheimer’s disease
  • Whether acupuncture can help insomnia
  • How two forms of mindfulness-based therapy compare with behavior therapy for treating insomnia.

Could You Have Sleep Apnea?

Do you snore loudly? Does your bed partner say that you make gasping or snorting sounds during the night? Do you fight off sleepiness during the day?

If you have any of these symptoms, talk to your health care provider. You might have sleep apnea—a condition in which sleep is disrupted because of pauses in breathing. For more information, visit the NHLBI Web site.

If You’re Considering Complementary Health Approaches for Sleep Problems

  • Talk to your health care providers. Tell them about the complementary health approach you are considering and ask any questions you may have. Because trouble sleeping can be an indication of a more serious condition, and because some prescription and over-the-counter drugs can contribute to sleep problems, it is important to discuss your sleep-related symptoms with your health care providers before trying any complementary health product or practice.
  • Be cautious about using any sleep product—prescription medications, over-the-counter medications, dietary supplements, or homeopathic remedies. Find out about potential side effects and any risks from long-term use or combining products.
  • Keep in mind that “natural” does not always mean safe. For example, kava products can cause serious harm to the liver. Also, a manufacturer’s use of the term “standardized” (or “verified” or “certified”) does not necessarily guarantee product quality or consistency. Natural products can cause health problems if not used correctly. The health care providers you see about your sleep problems can advise you.
  • If you are pregnant, nursing a child, or considering giving a child a dietary supplement or other natural health product, it is especially important to consult your (or your child’s) health care provider.
  • If you are considering a practitioner-provided complementary health practice, check with your insurer to see if the services will be covered, and ask a trusted source (such as your health care provider or a nearby hospital or medical school) to recommend a practitioner.
  • Tell all your health care providers about any complementary health approaches you use. Give them a full picture of what you do to manage your health. This will help ensure coordinated and safe care.

[News item] Health-care professionals should prescribe sleep to prevent, treat metabolic disorders, experts argue — ScienceDaily

Health-care professionals should prescribe sleep to prevent, treat metabolic disorders, experts argue — ScienceDaily.

Date:
March 24, 2014
Source:
The Lancet
Summary:
Evidence increasingly suggests that insufficient or disturbed sleep is associated with metabolic disorders such as type 2 diabetes and obesity, and addressing poor quality sleep should be a target for the prevention — and even treatment — of these disorders. Addressing some types of sleep disturbance — such as sleep apnea — may have a directly beneficial effect on patients’ metabolic health, say the authors. But a far more common problem is people simply not getting enough sleep, particularly due to the increased use of devices such as tablets and portable gaming devices.

Addressing some types of sleep disturbance — such as sleep apnea — may have a directly beneficial effect on patients’ metabolic health, say the authors. But a far more common problem is people simply not getting enough sleep, particularly due to the increased use of devices such as tablets and portable gaming devices.
Furthermore, disruption of the body’s natural sleeping and waking cycle (circadian desynchrony) often experienced by shift workers and others who work outside daylight hours, also appears to have a clear association with poor metabolic health, accompanied by increased rates of chronic illness and early mortality.

Is your office chair killing you? – The Globe and Mail.

Excerpt from the article

…For decades, hundreds if not thousands of studies have examined the relationship between our activity levels and our health. Only recently have researchers turned their attention to the consequences of sitting at a desk all day and lying on the couch all evening.

 

“We’re talking extensively and producing public health messages about what we don’t do. And we don’t talk at all about what we do do: We don’t move very much, but we do sit idle,” says Dr. Mark Tremblay, director of healthy active living and obesity research at the Children’s Hospital of Eastern Ontario Research Institute.

The average person now spends 9.3 hours a day sitting. People who sit for six or more hours per day are 40 per cent more likely to die within 15 years compared to someone who sits less than three hours a day, even if they exercise. Obese people sit 2½ hours more each day than people of normal weight, according to data compiled by Medical Billing and Coding, a U.S.-based organization….
