Melatonin, the natural hormone that regulates sleep-wake cycles. The role of melatonin in promoting restful sleep, and its benefits will be explored, providing insights into how you can optimize your sleep with this powerful hormone.
What Does Melatonin Do?
Melatonin operates through several mechanisms to regulate sleep:
Circadian Rhythm Regulation
Melatonin helps synchronize the body’s internal clock with the external environment, promoting a regular sleep-wake cycle.
Sleep Initiation
Melatonin promotes the onset of sleep by binding to melatonin receptors in the brain, which signals the body that it is time to sleep.
Antioxidant Properties
Melatonin acts as an antioxidant, protecting cells from damage by neutralizing free radicals.
Immune System Support
Melatonin has immunomodulatory effects, enhancing the function of the immune system.
What is Melatonin?
Melatonin is a hormone produced by the pineal gland in the brain. It is primarily responsible for regulating the sleep-wake cycle, also known as the circadian rhythm. Melatonin production is influenced by light exposure: levels rise in the evening as it gets dark and decrease in the morning with exposure to light, signaling to your body that it is time to sleep or wake up.
