The Role of Melatonin in Sleep

The Role of Melatonin in Sleep

Melatonin is a hormone produced by the pineal gland in the brain that regulates the sleep-wake cycle. It is often referred to as the «hormone of darkness» because its production is stimulated by darkness and inhibited by light.

When it gets dark, the pineal gland releases melatonin into the bloodstream, which signals to the body that it is time to sleep. This helps to synchronize the body’s internal clock and promote feelings of drowsiness.

Research has shown that melatonin supplements can be effective in treating insomnia and other sleep disorders, particularly in individuals with disrupted circadian rhythms, such as shift workers or those suffering from jet lag.

In addition to regulating sleep, melatonin also has antioxidant properties and plays a role in immune function. It is important to maintain a regular sleep schedule and limit exposure to bright light in the evening to support healthy melatonin production and improve overall sleep quality.
