Melatonin is a hormone produced by the pineal gland, a small endocrine gland located in the brain. It plays a crucial role in regulating the body’s sleep-wake cycle, also known as the circadian rhythm. Typically, melatonin levels rise in the evening, helping individuals fall asleep, and decrease in the morning, allowing them to wake up. However, there are instances where melatonin levels can be higher than usual, and it is essential to understand the reasons behind this elevation. In this article, we will delve into the causes, effects, and implications of high melatonin levels, providing valuable insights into the complex world of sleep regulation and hormone balance.
Introduction to Melatonin and Its Functions
Melatonin is often referred to as the “sleep hormone” due to its significant role in inducing sleepiness and regulating the sleep-wake cycle. However, its functions extend beyond sleep regulation. Melatonin is also involved in antioxidant activities, helping protect cells from damage caused by free radicals. Additionally, it plays a role in inflammation reduction and may have implications in various physiological processes, including reproduction and cardiovascular health.
