How long to fall asleep

On average most people fall asleep in 7 minutes. 

Your body’s internal clock is controlled by an area of the brain called the SCN (suprachiasmatic nucleus). 
The SCN is located in the hypothalamus. 


One of the most important chemicals involved in this process is melatonin, a hormone that makes us feel sleepy. The amount of melatonin in your body starts increasing in the evening and peaks in the middle of the night.

Most people sleep 8 to 9 hours a night. 
Scientists have found that sleeping too much can be as harmful as sleeping less than 6 hours each night.

The sweet spot for sleeping for most people is 7 to 9 hours a night.
