Melatonin is a hormone that is generated by the brain’s pineal gland and other tissues in the body. Melatonin is regulated and produced by your body’s internal clock. It is a hormone and is controlled by the suprachiasmatic nuclei, which helps to ensure that higher levels of melatonin are produced several hours before bedtime, with those levels then declining as you sleep.
The melatonin cycle operates roughly opposite of body temperature cycle. In late afternoon and early evening, the body temperature is the highest and the melatonin is the lowest. Conversely, in the early morning, the body temperature is at its lowest and the melatonin level is at its highest.
Supplementing melatonin can be used to shift your body’s internal clock to treat sleep disorders, depression, or jet lag. There are many ways of preventing yourself from accidentally reducing your own melatonin levels through changing of simple behaviors. These may include:
- Reducing amount of blue light exposure during afternoon and night time hours.
- Reducing the amount of caffeine, nicotine, and alcohol that is consumed.
- Daytime exercise and exposure to the sun to help regulate your circadian rhythms.
Benefits of Melatonin include:
- Helps regulate sleep schedules
