melatonin

Melatonin is a hormone produced by the pineal gland in the brain, primarily responsible for regulating sleep-wake cycles. It is often referred to as the 'sleep hormone' because its production increases in response to darkness, signaling the body to prepare for sleep. Melatonin supplements are commonly used to help improve sleep quality, particularly for individuals with sleep disorders such as insomnia or those experiencing disruptions in their sleep patterns due to jet lag or shift work. By mimicking the natural rise in melatonin levels, these supplements can aid in falling asleep faster and improving overall sleep duration and quality.
