The body is designed in such a way that it can only rest properly in complete darkness. And excessive lighting can negatively affect sleep not only during sleep itself, but also shortly before going to sleep.

How does light affect sleep?

The fact is that very important substances (including melatonin) are formed in the epiphysis (or pineal gland) only in complete darkness. If it is not present during sleep, the important regulatory function of the pineal gland is disturbed, little sleep hormone is formed, sleep becomes difficult, and sleep itself becomes shallow. And all this predisposes to various unfavorable consequences.

Eating behavior disorders

Including provokes insulin resistance, which in the long term can lead to diabetes. At the same time, it only took one night with the lights on to cause a spike in insulin during the experiment.
