Drowsiness At Night

Why are we sleepy at night? Or why when a rural community which had no electricity tend to sleep more quickly? The answer is because of the melatonin
hormone . SCN will tell your body to release the melatonin hormone if it was dark. Furthermore, the melatonin hormone will tell your body to rest. But with the presence of electric lights which made the atmosphere becomes bright at night inhibits the release of the melatonin hormone, which makes human sleeps at more late-night than ever before.

Our bodies are adaptable. For example, for workers who work at night, SCN will adapt in a release the hormone melatonin, so they will remain intact even though it was dark. When the night wore on, we will be more likely to feel sleepy, is due to the hormone melatonin produced increased and also lower body temperature and blood pressure in the body.
