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.

Factors Affecting How Long Melatonin Lasts
But how long does melatonin last in your system? Melatonin typically stays in your system for around four to eight hours, but this range largely depends on external factors, including:
- Age: Your metabolism slows as you age, meaning the rate at which your body can metabolize the melatonin also slows. The older you are, the longer it may take for melatonin to wear off.
- Caffeine: Research has shown that caffeine can modify melatonin production to counteract the effectiveness of the supplement.
- Light exposure: Exposure to bright light, especially the blue light emitted from technology, can send signals to your brain that its daytime, making it harder for the melatonin to take effect.
- Body size: Factors like your height and weight impact how you absorb melatonin and how it affects you.
- Tobacco use: In animal studies, nicotine has been shown to inhibit melatonins effectiveness in the body.
- Other medications: Additional medications like blood thinners, immunosuppressants, and stimulants may counteract the effectiveness of melatonin.
When To Take Melatonin
Its recommended take melatonin 30 to 60 minutes before bedtime. Thats because melatonin typically starts working after 30 minutes, when levels in your blood rise.
However, the best time to take melatonin is different for each person. Everyone absorbs medication at different rates. To start, take melatonin 30 minutes before bed. You can adjust the timing depending on how long it takes for you to fall asleep.
Whats most important is that you avoid taking melatonin at or after your ideal bedtime. This can shift your body clock in the wrong direction, resulting in daytime sleepiness.

What Taking Melatonin Every Day Does To Your Body
Melatonin is a hormone that helps regulate the body’s sleep-wake cycle, a.k.a. the circadian rhythm. Its levels increase at night, when it puts the body into a winding-down state that’s conducive to sleep. Our bodies produce it naturally, but some people take a melatonin supplement to help with insomnia or jet lag. But is it safe to take every day? Here’s what taking melatonin every day does to your body, according to science. Read on to find out moreand to ensure your health and the health of others, don’t miss these Sure Signs You’ve Already Had COVID.
Day : I Had Another Long Sleepy Day
The sixth day of my experiment was the day that solidified my choice to not continue taking melatonin after the week was over.
The daytime sleepiness I was experiencing started to completely overshadow the positive effects of gaining a regular sleep schedule. I had to take another midday nap and struggled to be as productive as I needed to be throughout the day.
I was reluctant to take the melatonin again, but with only a short time left I had to push through.

What Is Melatonin Exactly What Is It Used For
Its important to understand that melatonin isnt just a sleeping pill that will work for everybody. To understand why, we need to take a closer look at what melatonin is and the way it works.
Melatonin is a hormone produced by the pineal glanda pea-sized gland in the middle of our brain. Its purpose is to regulate our circadian rhythm, helping our body to fall in line with the natural dark/light cycles of the sun. When the sun goes down, our pineal gland gets turned on by the suprachiasmatic nucleus located in the hypothalamus. Once stimulated, melatonin levels rise quickly to make you sleepy.
However, if you are not in a dimly lit environment, the brain is tricked into thinking it is still daytime. Thats why you dont get sleepy when youre on your tablet or watching TV. The blue light emitted from electronic devices suppresses our natural production of melatonin. So even if we know we are tired and need to go to sleep, our brain is getting the opposite message from our surroundings.
Millions of people turn to supplemental melatonin to help them avoid another sleepless night, and while its known to be a natural sleep aid, melatonin may not work for everyone.

Melatonin is one of the most popular over-the-counter supplements for people who have trouble sleeping — and like so many others, I’ve tried it out in an effort to get better rest at night.
However, the few times I’ve taken any amount of the supplement, I’ve felt groggy and “hungover” for hours the next morning. My body’s negative reaction to melatonin seems to defeat the purpose of taking it in the first place: to feel more rested during the day. So, I decided melatonin’s not the best sleep aid for me.
Turns out, I’m not alone.
Below, Josh Axe, a clinical nutritionist and co-founder of Ancient Nutrition, shares the best alternatives to melatonin if you decide it’s not for you. Plus, he breaks down why melatonin can make you feel hungover — and how to prevent that effect if you choose to keep taking it.
Melatonin takes about an hour to work and lasts for about five hours, according to Josh Axe.

If Your Circadian Rhythm Is Constantly Shifting Melatonin Can Help
Your circadian rhythm is tied to the phases of light and dark that make up a day. However, some peoples internal clocks are out of sync with this 24-hour cycle. Individuals with non-24-hour sleep-wake disorder have a circadian rhythm that is either shorter or longer than 24 hours . This discrepancy between the length of their circadian rhythm and the 24-hour day progressively shifts their sleep and wake times.
As an extreme example, if someones rhythm is only 20 hours, they may feel sleepy at 10 p.m. one day but 6 p.m. the next day and 2 p.m. the day after. This constant shifting can lead to significant fluctuations in alertness, mood, and appetite and can make it very difficult to keep work and social commitments. Oftentimes, people with N24SWD have complete vision loss the condition is caused by the inability to perceive light. N24SWD can also affect sighted individuals, although the cause is unclear .
In a small study of sighted patients with N24SWD published in the Journal of Clinical Sleep Medicine in 2018, researchers found that melatonin, when timed correctly and combined with light therapy, could effectively train participants circadian rhythm to follow a 24-hour pattern. Most, however, chose not to continue the treatment after the study ended.

Side Effects Of Melatonin: 8 Groups Should Avoid Taking Melatonin
September 28, 2020// by Terry Cralle//
Melatonin, also known as the hormone of darkness is a hormone responsible for the regulation of your sleep-wake cycle. However, promoting and regulating sleep is only one of its physiological functions.
This hormone plays an important role in bodily functions, the functions of organs like the kidney or liver, and helps regulate blood pressure and cardiovascular issues. Melatonin is also shown useful in cases of tumors and cancers, where it prevents oxidative stress to promote the growth of cancerous cells.
Now, all of this sounds rather impressive, and sure enough, because melatonin is a naturally produced hormone coming from the very brain, no one would suspect it harmful. However, melatonin supplements, on the other hand, are raising some eyebrows in the medical community.
Over the past few years, melatonin supplements have been studied concerning their possible side effects. Turns out, melatonin intake can cause a dozen of adverse effects, which can pose a long-term danger. In the following paragraphs, well take a look at the major side effects, every melatonin producing company would hide from you. So, lets get started!

Day : Melatonin Helped Me Start Waking Up Earlier But Continued To Cause Me Drowsiness During The Day
Day four was a weekend and typically I use the weekend to sleep in as long as I want. I know it is best for your sleep cycle not to do this and that we all should aim to wake up at the same time every day, but as someone who struggles to sleep at night, there are times where weekend mornings are the only time I feel I can get an adequate amount of sleep.
On this morning, however, I naturally woke up much earlier than normal. It was very strange for me because I am not a morning person and typically require many alarms to get up at early morning hours.
I was pleasantly surprised at this and felt ready to take on the day until daytime sleepiness hit me in the afternoon. I was bummed about the daytime drowsiness because I truly enjoyed feeling like I was getting on a better schedule.
That evening, taking melatonin was helpful for easing some late-night anxiety I was experiencing. I was grateful for the help to get to sleep quickly and easily.
What To Know About Dietary Supplements And Safety
The FDA classifies melatonin as a dietary supplement, meaning that its regulated less strictly than a regular drug. For dietary supplements, label claims and product safety dont have to meet FDA approval before theyre marketed.
A 2017 study of 31 different melatonin supplements found that the actual melatonin content of 71 percent of the products didnt match the claim on the label. Additionally, 26 percent of products contained serotonin, which can be potentially harmful even in small doses.
When shopping for melatonin supplements, look for products that are USP verified. United States Pharmacopeia is an independent organization that works to ensure proper quality and dosing of dietary supplements.
- confusion or disorientation
- low blood pressure
If you experience side effects from melatonin, stop taking it and speak with your doctor. They may recommend using a lower dose or trying out an alternative medication or sleep aid.

Yes, it could cause insomnia.
If youre like the 88 percent of women regularly not sleeping through the night , youve probably found yourself looking for alternatives to counting sheep.
Last year, the National Institutes of Health reported that 3.1 million Americans used melatonin supplements to fall asleep. Melatonin is a natural hormone secreted by your brain that helps regulate your circadian rhythm, or when your body wants to wake up and go to sleep, says Jocelyn Cheng, M.D., a neurologist at NYU Langone Health.
Studies have actually shown that melatonin can help people with sleep disorders fall asleep anywhere between 27 and 50 minutes faster.
More From Women’s Health
But before you go buy out your local vitamin shop’s stock, remember: A supplement is not a regulated drug, so theres always a question as to whether youre getting what it claims to be, warns Rachel Salas, M.D., a neurologist with a focus on sleep disorders and sleep medicine at Johns Hopkins Medicine.
One study actually found that 71 percent of melatonin supplements did not meet the claims on the label, with some listing up to five times the amount of the hormone than it actually contained. Look for supplements displaying seals from the United States Pharmacopeial Convention or NSF International so you know the manufacturers are legit.

Summary
Melatonin levels naturally decrease as you get older. Supplementing with low doses may help improve sleep quality in older adults.
