Melatonin is a hormone that plays a crucial role in regulating sleep-wake cycles. Produced by the pineal gland in the brain, it is often referred to as the “sleep hormone” due to its key function in signaling the body when it is time to sleep. Its production increases in the evening, promoting sleepiness, and decreases in the morning, helping to wake us up. Understanding the effects of melatonin can provide insights into its potential benefits and uses.
