The role of melatonin in our body’s natural sleep cycle is an important one, governing when we sleep and wake.

For many people, lying awake at night trying to fall asleep for hours is a natural and common occurrence. When it takes forever to fall asleep, many people look to natural supplements, like melatonin, or pharmaceutical sleeping pills to help them find some rest.

Melatonin impacts both the mind and body, helping individuals sync their circadian rhythms, the body’s inner clock that dictates when we sleep and wake. These supplements are typically taken over other sleeping pills because they do not possess the same type of side effects.

Natural melatonin start to increase in your body when it is dark outside, this help to tell your body that is ready for bedtime.

WHAT DOES MELATONIN DO TO YOUR BODY?

So, we know that melatonin works directly with your body’s circadian rhythm or biological clock, having a huge impact on your internal system. Melatonin binds to receptors in your body to help you relax and get tired for bed. By taking melatonin your body is directly affected as your circadian rhythm starts to change and coincide with when you take the supplement. It is important that your body can prepare itself at night to get ready to rest. Achieving a restful sleep has a tremendous impact on all areas of health and well-being.

Melatonin is produced in the pineal gland at night and serves as a time to cue your biological clock to anticipate sleep in the brain. Melantonin also aids in antioxidant defenses and helps to regulate blood pressure, body temperature, cortisol levels and sexual and immune functions.
