Melatonin is a hormone produced by the pineal gland, a small endocrine gland located in the brain. It plays a crucial role in regulating our sleep-wake cycles, also known as our circadian rhythms. While melatonin is essential for a good night’s sleep, having too much of it can have negative consequences. In this article, we will explore what happens if your melatonin is too high, the risks and consequences associated with it, and what you can do to maintain a healthy balance.
What Is Melatonin and How Does It Work?
Before we dive into the effects of high melatonin levels, it’s essential to understand what melatonin is and how it works. Melatonin is a hormone that is produced by the pineal gland in response to darkness. It is released into the bloodstream and binds to receptors in the brain, promoting relaxation and sleepiness. Melatonin levels typically rise in the evening, peak during the night, and decrease in the morning.
Melatonin is often referred to as the “sleep hormone” because of its role in regulating our sleep-wake cycles. However, it also has other functions, such as:
- Regulating body temperature
- Influencing hormone secretion
- Antioxidant properties
- Immune system regulation
What Happens If Your Melatonin Is Too High?
Having too much melatonin can have negative consequences, including:
Sleep Disturbances
While melatonin is essential for sleep, having too much of it can disrupt sleep patterns. High melatonin levels can cause:
- Drowsiness during the day: Excessive melatonin can make you feel drowsy and lethargic during the day, affecting your productivity and daily activities.
