What is Melatonin?
Melatonin is a sleep-regulating hormone produced by the pineal gland in our brains. It plays a significant role in organizing our circadian rhythms, the 24-hour sleep-wake cycles that govern when we wake up, feel alert, feel tired, and sleep.
A wide range of factors can suppress melatonin production, particularly night-time exposure to light but also aging and some diseases. Since low melatonin levels can cause sleep disturbances, many people take supplemental melatonin in pill form. It is the fourth most popular natural supplement.
Melatonin is most often recommended for people with circadian rhythm conditions like delayed sleep-wake phase disorder or whose circadian rhythms are compromised by jet lag. It is also used for some sleep disorders in children. Some people also find melatonin helps with shift work-related sleep disturbances or insomnia, but the research is divided in terms of how effective it is for these problems.
