Melatonin is a naturally occurring hormone that helps regulate sleep. It is often called the sleep hormone because high levels can help you fall asleep. Melatonin supplements have become increasingly popular as a sleep aid, with nearly two-thirds of American adults having tried them. While melatonin can help some people fall asleep more easily, it is not a cure-all for sleep difficulties. This article will explore the effects of melatonin on sleep, including whether it increases sleep duration and quality without decreasing sleep quality.
| Characteristics | Values |
|---|---|
| Effectiveness | Melatonin can help people fall asleep faster and increase total sleep time. |
| It is particularly beneficial for people with insomnia, delayed sleep phase syndrome, respiratory diseases, metabolic disorders, and sleep disorders. | |
| It may also improve sleep quality and morning alertness in individuals with Alzheimer's disease. | |
| Safety | Melatonin is generally safe and non-toxic for most people, including children and adults. |
| It is not recommended for pregnant or breastfeeding women or those with autoimmune disorders, seizure disorders, or depression. | |

Melatonin is a naturally-occurring sleep hormone
Melatonin is a hormone that the body produces naturally. It is often referred to as the "sleep hormone" because high levels of it can help people fall asleep. Melatonin does not, however, cause you to fall asleep. Instead, it prepares your body for sleep by inducing a state of quiet wakefulness. Melatonin levels begin to rise in the body about two hours before bedtime, causing a gradual increase in sleepiness.
The body's production of melatonin is triggered by the sun going down, and it continues through the night, peaking about seven hours after sunset. This helps people stay asleep. Melatonin levels drop to undetectable levels in the morning as exposure to light inhibits its production, helping people feel alert when they wake up.
However, not everyone produces enough melatonin for sleep. In such cases, melatonin supplements may help. Research has shown that melatonin supplements may help people with insomnia fall asleep faster and increase total sleep time. They have also been found to improve sleep quality and morning alertness in individuals with Alzheimer's disease. Melatonin supplements are considered safe and non-toxic for both children and adults.
To improve your natural melatonin production, you can try to expose yourself to daylight during the morning and afternoon. Additionally, you should avoid screens and other electronic devices in the hours leading up to bedtime, as the blue light they emit can interfere with melatonin production.

Melatonin supplements may help with insomnia
Melatonin is a hormone that the body produces naturally. It is often referred to as the "sleep hormone" because high levels of it can help you fall asleep. However, it is important to note that melatonin does not directly make you fall asleep. Instead, it lets your body know that it is time for bed, allowing you to fall asleep more easily. Typically, the body starts producing melatonin every evening around sunset, causing a gradual increase in sleepiness. This production continues into the night, peaking about seven hours after sunset, and helping you stay asleep. By morning, melatonin levels drop to undetectable levels as exposure to light inhibits its production, making you feel alert.
For people who have difficulty falling asleep, taking melatonin supplements can be a solution. Research shows that melatonin supplements may help people with insomnia fall asleep faster and may be especially beneficial for those with delayed sleep phase syndrome, where they fall asleep and wake up very late. A 2019 review of 11 studies found that melatonin supplements decreased sleep latency by almost 3 minutes and increased total sleep time by about 30 minutes compared to a placebo. Another 2021 review of 23 studies involving people with disease-related sleep disorders found that melatonin significantly improved sleep quality and duration while reducing sleep disturbances and sleep latency.
If you are considering taking melatonin supplements, it is recommended to start with a low dose, typically 0.5 to 3 milligrams, 30 minutes to two hours before bedtime. The goal is to find the lowest dose that helps you sleep. It is also important to note that melatonin supplements are not a cure-all for sleep difficulties, and it is best to consult a healthcare professional to understand the source of your sleep issues and how melatonin works before taking it. Additionally, melatonin supplements are not recommended for those who are pregnant or breastfeeding or those with specific health conditions such as autoimmune disorders, seizure disorders, or depression.

Melatonin may improve sleep quality and morning alertness in people with Alzheimer's
Melatonin is a hormone produced by the pineal gland that regulates sleep-wake cycles, also called circadian rhythms. Our bodies produce melatonin naturally, and its levels typically rise in the evening, putting us into a state of quiet wakefulness that helps promote sleep. However, as we age, our bodies produce less melatonin, and this decrease is more pronounced in individuals with Alzheimer's disease and other dementias.
Research suggests that melatonin may improve sleep quality and morning alertness in people with Alzheimer's disease. A 2021 review of 23 studies found that melatonin significantly improved sleep quality and reduced sleep disturbances in individuals with disease-related sleep disorders. Another study found that melatonin supplementation decreased sleep latency by almost 3 minutes and increased total sleep time by about 30 minutes compared to a placebo.
Additionally, a 2021 meta-analysis of randomized controlled trials in people with Alzheimer's disease reported that melatonin treatment improved cognitive function in some individuals, suggesting that melatonin may have benefits beyond just sleep. However, more research is needed to fully understand melatonin's effects on the brain and Alzheimer's disease.
It is important to note that while melatonin is generally safe and non-toxic, it is always recommended to consult with a healthcare professional before starting any new supplement, especially if you have a medical condition or are taking medications.

They may be particularly useful for people with insomnia, those who want to overcome jet lag, or those who need to adjust their sleep schedule. Research shows that melatonin supplements may help people with insomnia fall asleep slightly faster and may have bigger benefits for those with delayed sleep phase syndrome, which involves falling asleep very late and waking up late the next day.
A 2021 review of 23 studies involving people with disease-related sleep disorders found that melatonin significantly improved sleep quality and duration while reducing sleep disturbances and sleep latency. Another review of 11 studies showed that melatonin decreased sleep latency by almost 3 minutes and increased total sleep time by about 30 minutes compared to a placebo.
While melatonin supplements may be helpful for some people, they are not a cure-all for sleep difficulties. It is important to understand how melatonin works and when to take it.

Melatonin is generally considered safe for most people, but there are some exceptions. It is not recommended for pregnant or breastfeeding individuals, and those with certain health conditions should exercise caution. This includes people with autoimmune disorders, seizure disorders, or depression, who should refrain from using melatonin. Additionally, those with diabetes or high blood pressure should consult a healthcare provider before taking melatonin, as it may impact blood sugar and blood pressure levels.
As a dietary supplement in the United States, melatonin is not subject to the same strict standards as pharmaceutical drugs. As a result, consumers should be cautious when choosing a melatonin product, as some may contain significantly less or more of the hormone than advertised. To ensure the best chance of obtaining a high-quality product, it is advisable to opt for reputable brands that provide accurate dosage information.
While melatonin is generally safe for short-term use, it is always advisable to consult a healthcare professional before starting any new supplement, especially if you have underlying health conditions or are taking medications. Additionally, it is important to address the underlying causes of sleep difficulties, as melatonin is not a cure-all for sleep problems.
