How does melatonin affect our sleep?

Melatonin is one of the essential ‘messengers’ for the circadian rhythm

A circadian rhythm is a biological rhythm that lasts approximately 24 hours and includes all of our natural biological rhythms, including the sleep-wake cycle.
Our sleep cycle is regulated by two hormones: cortisol, which promotes wakefulness and attention, and melatonin, often called the sleep hormone.

Generally, sleep occurs about 2-3 hours after the onset of melatonin secretion, which reaches a peak concentration in the blood in the middle of the night before gradually decreasing and giving way to cortisol, the wake-up hormone.

During the day, melatonin levels in the blood are very low. It is when the light decreases (around 8-9 p.m.) that its secretion increases in order to prepare the body for rest and sleep. In a healthy body, melatonin levels rise during the night. The peak of melatonin is generally reached between 1 am and 3 am (with slight variations depending on the season).

Melatonin production drops in the morning when the light returns. We then gradually wake up. The level of melatonin in the blood drops to almost zero by 9 o’clock. It usually remains at this low level throughout the day. In winter, however, due to the lack of light, it may increase slightly during the day.
It is very important to note that melatonin secretion can be blocked or interrupted by light during the evening or night.

The 5 stages of the sleep cycle:

Laboratoires Activa proposes a natural supplement with melatonin designed to reduce stress and support the circadian cycle using the technology of microgranule. An extended release formula that allows the release of the active ingredients over 8 hours as well as their gastroprotection for better absorption.
