What is melatonin

Melatonin is a hormone made by the pineal gland. That's a pea-sized gland found just above the middle of your brain. It helps your body know when it's time to sleep and wake up.

Normally, your body makes more melatonin at night. Levels usually start to go up in the evening once the sun sets. They drop in the morning when the sun goes up. The amount of light you get each day -- plus your own body clock -- set how much your body makes.


What is melatonin and what role does it play in sleepiness and wakefulness

Melatonin, often referred to as the sleep hormone, is a central part of the body’s sleep-wake cycle. Its production increases with evening darkness, promoting healthy sleep and helping to orient our circadian rhythm.


The body naturally produces melatonin, but researchers and the public have increasingly taken an interest in external sources of it, such as liquids or capsules, as a way to address sleep difficulties. In the United States, melatonin is sold as a dietary supplement, and a 2012 survey by the National Institutes of Health found it to be one of the most commonly used supplements among both adults1 and children2.


Studies have found that melatonin can improve sleep in certain cases, but it isn’t for everyone. It is important to be aware of and carefully consider melatonin’s potential benefits and downsides. People who want to use melatonin supplement should also be aware of issues related to dosage and the quality of supplements.

Natural melatonin is a highly lipid soluble hormone produced in the pineal gland in the brain. It is synthesized from the amino acid tryptophan and then released into the blood and cerebrospinal fluid, crossing the blood-brain barrier. It sends messages to the receptor agonist in the brain and other areas of the body to help control the sleep and wake cycles.


What is melatonin in psychology

n. an amine hormone, produced mainly by the pineal gland as a metabolic product of the neurotransmitter serotonin, that helps to regulate seasonal changes in physiology and may also influence puberty. It is implicated in the initiation of sleep and in the regulation of the sleep–wake cycle. Melatonin has been investigated in clinical studies as a hypnotic and for the management of circadian rhythm sleep disorders. Although these studies are as yet inconclusive, melatonin is widely available as an over-the-counter medication.

The hormone melatonin plays a role in your natural sleep-wake cycle. Natural levels of melatonin in the blood are highest at night. Some research suggests that melatonin supplements might be helpful in treating sleep disorders, such as delayed sleep phase, and providing some relief from insomnia and jet lag.


Melatonin is generally safe for short-term use. Unlike with many sleep medications, with melatonin you are unlikely to become dependent, have a diminished response after repeated use (habituation), or experience a hangover effect.


What is melatonin side effects


A few studies have investigated the safety of melatonin, but none have revealed any serious side effects. It also doesn’t seem to cause any dependence or withdrawal symptoms (5Trusted Source, 6Trusted Source).


Nonetheless, some medical practitioners are concerned that it may reduce the natural production of melatonin in the body, but short-term studies suggest no such effects (7Trusted Source, 8Trusted Source, 9Trusted Source).


Several studies have reported general symptoms, including dizziness, headache, nausea or agitation. However, these were equally common in the treatment and placebo groups and couldn’t be attributed to melatonin (5Trusted Source).


Melatonin supplements are generally considered safe in the short-term, even when taken in very high doses. However, more research on its long-term safety is needed, especially in children (10Trusted Source).

What does melatonin do to your body?

Melatonin is a hormone that your brain produces in response to darkness. It helps with the timing of your circadian rhythms (24-hour internal clock) and with sleep. Being exposed to light at night can block melatonin production.


Research suggests that melatonin plays other important roles in the body beyond sleep. However, these effects are not fully understood.


Melatonin dietary supplements can be made from animals or microorganisms, but most often they’re made synthetically. The information below is about melatonin dietary supplements.


Is melatonin a drug?


Melatonin is sold over the counter (OTC) in health food stores and drug stores in the United States. Like other dietary supplements, it's regulated by the U.S. Food and Drug Administration (FDA). However, it's not approved for certain uses. Because of this, its purity, safety, and success can't be guaranteed.


How does melatonin make you feel?

Melatonin is a hormone that controls your circadian rhythm. Your body makes it when you're exposed to darkness. As your melatonin levels increase, you start to feel calm and sleepy.
