Melatonin is a naturally occurring hormone that plays a vital role in regulating sleep and wakefulness. It is produced in the pineal gland, a small gland located in the center of the brain. Melatonin levels rise in the evening and fall in the morning, following a circadian rhythm. This helps to promote feelings of sleepiness at night and alertness during the day.
Melatonin is available as a dietary supplement and is often used to treat sleep disorders, such as insomnia and jet lag. It is generally considered to be safe for short-term use, but there is some concern that taking too much melatonin could have negative side effects.
In this article, we will discuss the potential risks of taking too much melatonin and provide some tips for using melatonin safely.
