Introduction to Melatonin and Its Benefits
Melatonin is a natural hormone produced by the pineal gland, a small gland located in the brain. Its primary function is to regulate the body’s circadian rhythms, signaling the body when it’s time to sleep and wake up. Melatonin levels typically rise in the evening, promoting sleepiness, and decrease in the morning, allowing us to feel alert and awake. Supplements containing melatonin have become increasingly popular, as they can help individuals with sleep disorders, such as insomnia, and those experiencing jet lag or shift work sleep disorder.
The benefits of melatonin are numerous, including:
- Improved sleep quality: Melatonin can help individuals fall asleep faster and stay asleep longer, leading to better rest and relaxation.
- Increased sleep duration: By regulating the body’s internal clock, melatonin can help increase the amount of time spent sleeping, leading to improved physical and mental health.
