Melatonin is a hormone that is naturally produced by the pineal gland in the brain. It plays a crucial role in regulating the sleep-wake cycle, commonly known as the circadian rhythm. Melatonin levels typically increase in response to darkness and decrease when exposed to light, helping to signal to the body that it is time to sleep.
As we age, the production of melatonin can decrease, which may contribute to sleep-related issues in older adults. Melatonin is also available as a dietary supplement, commonly used to address sleep disorders such as insomnia, jet lag, and the sleep disturbances associated with shift work. It is synthesized in the laboratory and marketed as a supplement that can be taken orally, typically in tablet or capsule form.
Research suggests that melatonin supplements can help reduce the time it takes to fall asleep and may improve sleep quality in certain populations, including older adults and individuals with specific sleep disorders. However, the effects of melatonin on overall sleep time and quality are still being studied.
Melatonin supplements are generally considered safe for short-term use, but they can cause side effects such as headache, dizziness, nausea, and drowsiness. It is recommended to consult with a healthcare provider before taking melatonin, especially for long-term use or for individuals with certain health conditions.
