Does Melatonin Work For Shift Workers

Does Melatonin Work for Insomnia?

Shift work that involves night shifts may cause people to feel sleepy at work and make it difficult to sleep during the daytime after a shift ends.

According to two 2014 research reviews, studies on whether melatonin supplements help shift workers were generally small or inconclusive.

  • The first review looked at 7 studies that included a total of 263 participants. The results suggested that people taking melatonin may sleep about 24 minutes longer during the daytime, but other aspects of sleep, such as time needed to fall asleep, may not change. The evidence, however, was considered to be of low quality.
  • The other review looked at 8 studies , with a total of 300 participants, to see whether melatonin helped promote sleep in shift workers. Six of the studies were high quality, and they had inconclusive results. The review did not make any recommendations for melatonin use in shift workers.

What Are The Health Benefits Of Taking Melatonin

Melatonin supplements may help with certain conditions, such as jet lag, delayed sleep-wake phase disorder, some sleep disorders in children, and anxiety before and after surgery.

Jet lag

Jet lag affects people when they travel by air across multiple time zones. With jet lag, you may not feel well overall and you may have disturbed sleep, daytime tiredness, impaired functioning, and digestive problems.

Research suggests that melatonin supplements may help with jet lag. This is based on medium-sized reviews from 2010 and 2014.

  • Four studies that included a total of 142 travelers showed that melatonin may be better than a placebo in reducing overall symptoms of jet lag after eastward flights. Another study of 234 travelers on eastward flights looked at only sleep quality and found low-quality evidence that melatonin may be better than placebo for improving sleep quality.
  • Two studies that included a total of 90 travelers showed that melatonin may be better than a placebo in reducing symptoms of jet lag after westward flights.

Delayed sleep-wake phase disorder

People with DSWPD have trouble falling asleep at the usual times and waking up in the morning. They typically have difficulty getting to sleep before 2 to 6 a.m. and would prefer to wake up between 10 a.m. and 1 p.m.

Some sleep disorders in children

Because of these uncertainties, itâs best to work with a health care provider if youâre considering giving a child melatonin for sleep problems.

How Melatonin Helps Insomnia

Melatonin is a very important hormone that is secreted naturally by the human body. It’s primary function is helping to keep our circadian rhythms – or body clocks – in check. When those clocks get out of whack, insomnia is a common result. Many people who struggle with insomnia find themselves eager to try sleep aids – natural sleep aids that include melatonin have been effective in managing the symptoms of insomnia.

The link between melatonin and insomnia seems to become stronger and stronger with every passing years, as more and more studies show a connection between the two. Interestingly, insomnia is much more common in older people – and levels of melatonin naturally begin to decline with age. If you suffer from insomnia, you should definitely look into melatonin and find out more about what it can do for you.

What Are Melatonin Supplements

The brain normally makes only a very small amount of melatoninaround 0.2 milligrams, Brandon Peters-Mathews, MD, a sleep medicine specialist at Virginia Mason Medical Center in Seattle, tells Health. For some people, that might not be enough to help them get the rest they need. So melatonin supplements, which typically contain higher doses than the amount your body naturally releases, can be useful to treat sleep disorders and insomnia.

Supplemental melatonin allows us to get drowsy and ready for sleep,” says Dr. Malow. “In addition, melatonin can be calming and help us turn our brains off.”

Research backs this up, showing that melatonin can reduce the time it takes for people with delayed sleep phase wake disorder to fall asleep. Another study, published in Journal of Physiology-Paris, found that melatonin might also help reset the bodys sleep-wake cycle. Other small studies suggest that supplementary melatonin can ease anxiety and jet lag.

Melatonin is a prescription medication in Europe, but in the US it qualifies as a dietary supplement, meaning its available over the counter without a prescription at drugstores and health-nutrition retail outlets. Not all brands of melatonin are the same, though, and its important to read the label and make sure you are getting pure melatonin and not melatonin mixed with other substances, warns Dr. Malow.

Melatonin is generally safe for most people, and many people wont experience major complications when taking too much. Even so, an overdose can cause unpleasant side effects.

Keep your dose to no more than 1 to 3 mg per night. See your doctor for any serious side effects or if sleep problems dont improve after a few weeks. You may need to consult a sleep specialist.

A sleep specialist can help diagnose a sleep disorder, as well as make other suggestions to help you get a better nights sleep.

What About Melatonin Supplementation In Children And Teens

Several studies support melatonin use in children with sleep onset insomnia who may need long-term medication therapy, including those with autism spectrum disorder or ADHD. It should not be used in healthy children without sleep problems to promote restful sleep, or in adolescents to force sleep onset and accommodate early school start times. Studies of melatonin for durations up to 4 years have failed to demonstrate adverse effects in children. However, it is important to know that long-term side effects can include suppression of sex hormones . Rapid discontinuation in these circumstances could cause early puberty. I typically suggest my patients start by taking 0.3 mg a few hours before bed and to adopt sleep hygiene practices that will help to prevent the long-term use of melatonin.

May Help Increase Growth Hormone Levels In Men

Human growth hormone is naturally released during sleep. In healthy young men, taking melatonin may help increase HGH levels.

Studies have shown that melatonin can make the pituitary gland, the organ that releases HGH, more sensitive to the hormone that releases HGH .

In addition, one small study showed that both lower and higher melatonin doses are effective at stimulating HGH release .

Another study found that 5 mg of melatonin combined with resistance training increased the levels of HGH in men while lowering the levels of somatostatin, a hormone that inhibits HGH .

Summary

Melatonin may support eye health, ease tinnitus symptoms, treat stomach ulcers and heartburn, and increase growth hormone levels in young men. Speak with a healthcare professional first if youre considering melatonin supplementation to help treat any of the conditions mentioned to learn if its right for you and whether there are any medication interactions.

Dr Culvers Take Home Points The Need To Know

  • Melatonin is a hormone, not a sleeping medication. It does not work for everyone.
  • Melatonin tells your body its bedtime. It will not prevent you from waking during the night and it will not help you fall back asleep.
  • Stick to physiologic dosing. 0.3 1mg several hours before bedtime is best in initiating sleep because it encourages your bodys own production of melatonin. Physiologic doses vary by age.
  • Stay away from high dosages! Dosages of 10-50mg have been used in numerous cancer studies. Also, high amounts of melatonin have known to disrupt hormones like estrogen, progesterone, and testosterone.
  • Yes, its used in adjunctive cancer care but by professionals who know what theyre doing!
  • Purchase physician-onlybrands Youre more likely to have consistency in dosage and ingredients.
  • Talk to a doctor who is knowledgeable about herbs and supplements.

    How Else Can You Improve Your Sleep Quality

    Should I Take Melatonin For Sleep

    “Melatonin works synergistically with other practices,” says Dr. Dow. “You’ll get the best results by combining a melatonin supplement with simple sleep hygiene strategies like keeping a consistent bedtime, exposing yourself to natural light first thing in the morning, and keeping the bedroom very dark and cool.” That includes avoiding blue light, so no scrolling through your phone or staring at the clock.

    Most importantly, you’ll want to seek medical guidance to find the root of your insomnia. “As a sleep clinician, I first ask why is this person not sleeping?” Dr. Singh says. “That’s the fundamental thing.” Mental health and quality sleep go hand-in-hand, and melatonin alone can’t fix those kinds of issuesnor can it cure chronic, long-term insomnia. So, if you think you need to take melatonin everyday, don’t. Instead, talk to your doctor about more effective strategies and treatments for long-term relief.

    How Much Melatonin Is Safe Per Day

    Melatonin is generally safe if you take the correct dosagethis is any amount between 0.3 mg and 5 mg. Emerging science shows that 0.5 mg melatonin dosage may be all that you need to rebalance your sleep cycle. Higher dosages of the hormonal medication can increase the severity of side effects such as headaches and gastrointestinal disturbances.

    When Is The Best Time To Take Melatonin

    There are two answers to this question depending upon the symptoms youre targeting. Normally, the brain begins to produce melatonin around 9pm. If youre looking to encourage your bodys own production of melatonin, then taking melatonin 3 hours before your bedtime in a small dose is best because exogenous melatonin given earlier than the time of its usual endogenous secretion helps to shift the circadian rhythm earlier.

    Plasma levels of melatonin peak within one hour of administration. Therefore, if you want to fall asleep earlier to help re-establish a healthy bedtime , then taking melatonin 30 minutes to 1 hour before wanted sleep is recommended.

    If youre wide awake in the middle of the night, taking an additional dose will not help.

    Treatments And Data Analysis

    Subjects were blind to all the experimental treatments. They received a placebo on alternate weeks throughout the study, starting with the first run-in week, thus providing washout periods between and after active treatments. During the second week and thereafter on each even-numbered treatment week, subjects received, in gelatin capsules, melatonin mixed with microcrystalline cellulose or the placebo daily, administered double blind according to a randomized study design for 4 d at home and then for 3 d as inpatients in the MIT Clinical Research Center. Melatonin or placebo capsules were ingested half an hour before each subjects fixed bedtime. Each subjects actual times of ingestion and of bedtime, as well as their subjective assessments of sleep quantity and quality at home, were monitored by having them leave telephone messages immediately after ingesting a capsule, by sleep reports, and by continuous wrist actigraphy.

    Thirty subjects completed the study. Eleven of the 15 subjects initially classified as insomniac, based on subjective and actigraphic data, did in fact demonstrate insomnia on overnight PSG recordings obtained after ingesting the placebo. Fourteen of the 15 subjects originally classified as having normal sleep were also found not to be insomniac on PSG recordings.

    Is it safe to take melatonin?

    Its generally considered safe for most adults when taken by mouth for short periods of time. However, for the most benefits, its really important not to overdo it.

    People commonly take too much, especially initially, or they take a pill too soon before bed, decide it isnt doing the job quick enough and take another.

    Some people also wake up during the night and take another melatonin dosage. Its important to know that higher doses of melatonin dont equate to better sleep.

    In fact, taking too much can have the opposite of the desired effect and disrupt sleep.

    Can you take melatonin every night?

    Long-term melatonin use can be safe for some people. Melatonin has been used safely for up to two years.

    However, check with your doctor before taking melatonin for longer than a month or two.

    According to Johns Hopkins sleep expert Luis F. Buenaver, Ph.D., C.B.S.M., you should stop taking melatonin if it doesnt work after a week or two. He also advises, if its helpful, most people can safely take it nightly for one to two months, but after that, its a good idea to stop and see how you sleep without it.

    What are the most common melatonin side effects?

    For some people, melatonin side effects can include dizziness, headaches, nausea or irritability. Some also experience vivid dreams or nightmares.

    Melatonin nightmares are typically a sign that you need to decrease how much youre taking. You never want to start out with the max dose.

    How Do Our Sleep Patterns Change As We Age

    There is a common misconception that people need less sleep with age. The truth is, though, people aged 50 years and older need the same 7-8 hours of sleep.

    So, is the sleep of an elderly person different from that of an adult? Due to a decrease in melatonin production, older people need an average of 30 minutes longer to fall asleep. Besides, they often have a more sensitive sleep, which means a shifted balance between REM and non-REM stages as well as an increased likelihood of sleep fragmentation .

    Circadian rhythms also shift with age, so the elderly often go to bed earlier than usual and get up earlier too. Sleep patterns changing with age is a normal physiological process, but sleep quality of older people is often significantly disrupted by sleep-related problems or chronic illnesses such as:

    • snoring or sleep apnea
    • neurodegenerative diseases such as dementia or Alzheimer’s disease

    All these conditions can over time result in a chronic lack of sleep.

    May Support Eye Health

    Healthy indole-derived melatonin levels may support eye health.

    It has powerful antioxidant benefits that could help lower the risk of eye diseases, such as age-related macular degeneration .

    In one study, scientists asked 100 people with AMD to take 3 mg daily of melatonin over 6 to 24 months. Taking melatonin daily seems to protect the retinas and delay damage from AMD, without any significant side effects (

    Melatonin: Dosage Reviews& Safety

    Melatonin is a hormone found naturally in the body and made synthetically to promote sleep. It is also a popular supplement used for treating insomnia. Even though there is no conclusive evidence on its effectiveness, sales of melatonin in the US exceeded a billion dollars in 2019. Like all supplements and medications, users should understand the drugs uses, side effects, interactions, and dosages.

    The Science Behind Melatonin

    AIWO Health Melatonin

    Melatonin , chemically N-acetyl-5-methoxytryptamine, is a substance found in animals, plants, fungi and bacteria. In animals, its a hormone that anticipates the daily onset of darkness.

    In animals, melatonin is involved in the synchronization of the circadian rhythms of physiological functions including sleep timing, blood pressure regulation, seasonal reproduction and many others. Many of its biological effects in animals are produced through activation of melatonin receptors, while others are due to its role as a pervasive and powerful antioxidant, with a particular role in the protection of nuclear and mitochondrial DNA.

    The hormone can be used as a sleep aid and in the treatment of some sleep disorders. It can be taken orally in liquid form as well as capsules or tablets in immediate- or prolonged-release form. It is also available in a form to be used sublingually, and as transdermal patches. Melatonin is sold as an over-the-counter sleep aid in the U.S. and Canada. In other countries it may require a prescription or it may be unavailable.
