Melatonin is a hormone primarily produced by the pineal gland in the brain, known for its crucial role in regulating sleep-wake cycles. As night falls and darkness increases, melatonin production ramps up, signaling to the body that it’s time to prepare for sleep. This natural rhythm, known as the circadian rhythm, is essential for maintaining optimal sleep patterns and overall health.
