How Does Melatonin Affect Sleep
According to neuroscientist Andrew Huberman, if sunlight reaches our eyes soon after we wake up, it triggers a neural circuit that controls the timing of cortisol and melatonin. This is important for gaining feelings of wakefulness early in the day, as the presence of light is aligned to our circadian rhythm. However, this rhythm can be disrupted by exposure to light at times that do not reflect our external environment. A classic example of this is jet lag: it takes most of us a short while to readjust our body clocks after flying for hours through different time zones. This is because our circadian rhythm is lagging behind our levels of dopamine and cortisol, as a result of our irregular overstimulation by light. Since melatonin helps prime you to fall asleep, if there is not enough produced in your body at night-time, you may have difficulty getting high-quality sleep. This is because the bodys natural production of melatonin responds to stimuli from our environment. Times of low light levels, such as during evening darkness, prompt the release of this sleep hormone. Research has found, furthermore, that compared to green light wavelengths blue light is a particularly acute suppressor of melatonin, shifting circadian rhythms by twice as much!
Can You Use Melatonin For Anxiety Heres What The Experts Say
Melatonin supplements have been used for decades to promote sound, natural sleep. Whenever we have trouble getting shut-eye, this natural hormone thats also produced by our brains pineal gland can come to the rescue.
While melatonin may help combat sleep problems or even sleep disorders, recent clinical trials suggest this natural hormone can improve anxiety disorders too. Some believe this is because melatonin improves sleep, which reduces anxiety, while others suspect melatonin may directly impact anxiety symptoms to counteract this mental health disorder.
So, whats really happening beneath the surface? Read on to learn how melatonin may help your anxiety, how you can use it, what potential side effects it may have, and more.
Considering Melatonin For Sleep Heres A Guide To Help
Its understandable that you may be struggling to fall asleep these days. Our world has been turned upside down, so it is especially hard to unplug from the day and get the high-quality sleep your body needs.
Almost every single patient Im speaking with has insomnia, said Dr. Alon Y. Avidan, a professor and vice chair in the department of neurology at the David Geffen School of Medicine at the University of California, Los Angeles, and director of the U.C.L.A. Sleep Disorders Center. Especially now with Covid-19, we have an epidemic of insomnia. We call it Covid-somnia.
An increase in anxiety in both children and adults is affecting our ability to fall asleep. Additionally, our lifestyles have changed drastically as people observe sheltering in place guidelines. With more people staying indoors, it can mean they are not getting enough light exposure.
Without light exposure in the morning, Dr. Avidan said, people lose the circadian cues that are so fundamentally important in setting up appropriate and normal sleep-wake time.
There are nonmedical ways to help you sleep better: Meditation,turning off screens early in the night, warm showers and cool bedrooms can help your body rest better. But if these options dont work, or if you are ready for the next step, you may have considered trying melatonin supplements. These pills are commonplace enough that you have most likely heard of them and seen them in your local pharmacy.

Does Melatonin Really Help You Sleep
This naturally occurring sleep hormone may not be as effective or safe as you think
Sleep troubles have long been a common complaint for Americansand the stresses of the COVID-19 pandemic seem to have wreaked further havoc on our ability to get a good nights rest.
Fifty-six percent of Americans say theyve experienced an increase in sleep disturbances since the start of the COVID-19 pandemic, most commonly reporting trouble staying or falling asleep, according to an April 2021 survey of more than 2,000 people by the American Academy of Sleep Medicine . And we hadnt been resting easy before. In 2018, 80 percent of adults in the U.S. said they struggled with sleep at least once a week, according to a nationally representative Consumer Reports survey of 1,767 adults.
In searching for relief, many turn to dietary supplements. Just over half of Americans say theyve used supplements, medications, or other substances to help them fall asleep, according to the AASM, with 68 percent saying they used sleep aids more frequently than before.
The most popular supplement for sleep, by far, is melatonin, a hormone naturally produced by the body that governs our sleep-wake cycle. In 2020 melatonin sales grew a staggering 42.5 percent, to $687 million, according to Nutrition Business Journal, perhaps driven just not by the desire for more shut-eye but also by reports suggesting it may help protect against COVID-19.
Is that money well spent?

How Can I Get Better Quality Sleep
It would be useless to substitute natural light in the morning with blue light from your phone or laptop screen. Equally, it is detrimental to your sleep quality and pattern, and therefore your overall health. This is because the wavelengths of blue light have the most powerful impact on the bodys internal clock. Since blue light neutralises the effects of melatonin, Huberman continues, if you’re looking at your phone at 1 AM, you might as well have flown to Abu Dhabi.
How To Use Melatonin
- Melatonin is readily available in various forms including capsules, tablets, liquid extract, topical creams, and lozenges.

Make Sure You Are Getting What The Label Says
Before you buy melatonin, its important to make sure you are getting it from a reputable place. The F.D.A. does not regulate supplements, Dr. Kolla said. So youre trusting the manufacturer in terms of the dosing.
A 2017 study in the American Academy of Sleep Medicine found that the melatonin content of dietary supplements often varies widely from what is listed on the label. The study found that even within the same batch of product, variability of the melatonin varied by as much as 465 percent.
Without governmental oversight, there really isnt a way to ensure the levels of melatonin advertised on the package are accurate. Therefore, Dr. Kolla recommends looking for a GLP or GMP label on the product. Both labels refer to federal regulations designed to affirm a product has the quality and purity that appear on its label. He says this provides some assurance that you are getting close to what the label says youre getting.
Melatonin May Work Best For Jet Lag And In People Who Have Low Melatonin
When a person is jet lagged, their body’s clock is off from the clock of their destination. This can make it hard to sleep.
Melatonin may be particularly helpful for jet laggers because it can both help change a person’s internal clock to match local time, and it can help them sleep after a long, restless flight.
In 2002, the Cochrane Library conducted a systematic review of melatonin’s ability to help a person readjust to a new sleep schedule after jet lag at doses as small as .5 milligrams. “Melatonin is remarkably effective in preventing or reducing jet lag, and occasional short-term use appears to be safe,” the review concluded, especially when used after eastward flights. “Eight of the ten trials found that melatonin, taken close to the target bedtime at the destination , decreased jet-lag from flights crossing five or more time zones.”
Melatonin also seems to work much better for certain individuals.
“If your sleep problem results from a deficiency of the hormone melatonin, then melatonin will be very effective for your sleep problem,” Wurtman says. If sleep problems stem from anxiety, for instance, it will be less effective.
Scheer also notes that melatonin doesn’t follow a typical dose-response curve. That means taking a higher dose of melatonin doesn’t necessarily result in more sleepiness.

What If I Can’t Take Melatonin Or It Doesn’t Work Or Me
If melatonin isnt helping with sleep after a week or two of nightly use, Dr. Malow recommends checking in with your doctor about other options. Also, make sure you are taking a wider behavioral approach, including limiting caffeine after early afternoon, limiting alcohol, and turning screens off at least 30 minutes before bedtime, she says.
Does Age Impact Melatonin Production
The short answer is yes. Melatonin production decreases as we get older and the drop off starts early, with research showing the highest melatonin levels are found in kids ages 4 and under. Thats completely normal and makes sense we need less sleep as we get older and stop growing.
Still, it doesnt mean you cant be proactive. For years, Ive recommended taking a small dose of melatonin for adults who have a hard time falling asleep. Well get into dosage more in just one second.

Kevin Loria
I’m a science journalist who writes about health for Consumer Reports. I’m interested in finding the ways that people can transform their health for the better and in calling out the systems, companies, and policies that expose patients to unnecessary harm. As a dad, I spend most of my free time trying to keep up with a toddler, but I also enjoy exploring the outdoors whenever possible. .
Best Time To Take Melatonin
Studies support taking melatonin between 30 minutes and two hours before bedtime. The range exists because everyone absorbs medications at different rates and your own body’s melatonin production can affect how quickly supplemental melatonin works.
The most important thing is to avoid taking melatonin too late at night — like way after your bedtime — lest your sleep cycle get shifted and you have to drag yourself out of a cycle of late nights.

Medical professionals may recommend melatonin for children with conditions that affect their sleep, such as insomnia, autism spectrum disorder, or attention-deficit hyperactivity disorder. Several studies have shown melatonin supplements can significantly improve overall sleep times by 25 minutes to 48 minutes, on average, for children with these conditions.
However, there havent been enough studies of melatonin in children for experts to determine an official recommended dosage or any potential long-term safety risks. Since melatonin is a hormone, its possible that taking supplemental melatonin could affect other aspects of hormone development in children, but further research is needed.
If your child is having sleep problems, experts recommend consulting your doctor before giving them melatonin. Research indicates that for half of the cases where melatonin was used to treat pediatric insomnia, better sleep habits were just as effective at relieving the childs sleep problems.
Using Melatonin For Anxiety
Using melatonin for anxiety is as simple as taking a melatonin supplement before bed. These supplements come in tablet form and can be taken by mouth or dissolved under the tongue. Clinical studies suggest taking 3-10 milligrams before bed for optimal results. Higher doses of melatonin do not necessarily work better.
As you begin looking for melatonin supplements, look for reputable, high-quality options. Supplements like melatonin arent regulated by the Food and Drug Administration , so it pays to do your research and find reliable and trusted options. For example, some supplements are verified by the United States Pharmacopeia, which means theyll be free of contaminants and safe to consume.

What Happens If I Have Too Much Or Too Little Melatonin
Too little melatonin can lead to sleep problems, depression and other mental illnesses. Too much melatonin can cause headaches, drowsiness, dizziness and nausea.
The bodys natural melatonin level tends to go down as we age. Low levels of melatonin can also be caused by not having enough sleep, travelling across time zones, doing shift work and taking some medicines. Caffeine, alcohol and nicotine can also lower melatonin levels.
In some people, melatonin levels are too high. This can happen because they:
- are taking too many melatonin pills
- remain in the dark for too long
- are taking some medicines
- have seasonal affective disorder
