멜라토닌을 외부에서 얻을 수 있는 방법은 무엇인가?
Melatonin is a hormone that regulates sleep-wake cycles. This hormone is primarily produced by the pineal gland. As a medication, it is used for the short-term treatment of trouble sleeping such as from jet lag or shift work. Evidence of benefit, however, is unclear. One review found onset of sleep occurred 6 minutes faster with use but found no change in total time asleep. It may work as well as the medication ramelteon. It is typically taken by mouth.
Side effects from supplements are minimal at low doses for short durations. Side effects may include sleepiness, headaches, nausea, and abnormal dreams. Use is not recommended during pregnancy or breastfeeding. Use is also not recommended in those with liver problems.
In animals, melatonin is involved in synchronizing the circadian rhythms including sleep-wake timing, blood pressure regulation, and seasonal reproduction. Many of its effects are through activation of the melatonin receptor, while others are due to its role as an antioxidant. In plants it functions to defend against oxidative stress. Melatonin is also present in various foods.
Melatonin was discovered in 1958. It is sold over the counter in Canada and the United States. In the United Kingdom it is a prescription-only medication. A month's supply costs about $US 1 to 4 in the United States. In the United Kingdom a month's supply costs the NHS about 15 pounds per month. It is not FDA-approved for any use. In Australia and Europe, it is approved for trouble sleeping in people over the age of 54.
