Ever wonder why you start to feel sleepy around the same time each night? Or why traveling across time zones throws off your entire schedule? The answer lies in your body’s internal clock — the circadian rhythm — and a powerful hormone called melatonin. Often referred to as the “sleep hormone,” melatonin plays a crucial role in regulating when you feel alert and when it’s time to wind down.
Produced by the pineal gland in response to darkness, melatonin signals the body that it’s time to prepare for rest. But melatonin isn’t just about sleep — it’s an essential regulator of your entire circadian system. In this article, we’ll explore how melatonin influences your sleep-wake cycle, how modern life disrupts this rhythm, and natural ways to optimize your melatonin production for better rest and overall well-being.
