Melatonin is a hormone that your body naturally produces, primarily in the pineal gland, located deep within your brain. This hormone plays a crucial role in regulating your sleep-wake cycle, also known as the circadian rhythm. As darkness falls, your body ramps up melatonin production, signaling to you that it’s time to wind down and prepare for sleep.
Conversely, when the sun rises, melatonin levels drop, helping you feel more alert and awake. This natural rhythm is essential for maintaining a healthy sleep pattern and overall well-being. In addition to its role in sleep regulation, melatonin is also available as a dietary supplement.
Many people turn to melatonin supplements to help with various sleep-related issues, such as insomnia or jet lag. These supplements can mimic the natural hormone’s effects, making it easier for you to fall asleep and stay asleep. However, understanding how melatonin works and its broader implications for health is essential before incorporating it into your routine.
