Scientists agree and say that sleep must take place in total darkness. When the sun rises and daylight appears, our light receptors send a clear message to the brain that it is time to wake up. When night falls, the brain receives a signal that it is time to sleep, so sleep hormone is released. If during sleep you are in contact with a light source that will not sleep.
This is because light significantly affects how the body and the rhythm of sleep and wakefulness.
restless sleep, which occurs from the light sleep, can result in bad mood, sleepiness, and difficulty waking up.
Neurological studies have shown that sleep with resulted in a PC or TV or any other light leads to bad mood.
therefore, if you have the habit of sleeping with the TV or the computer is on, you need to try to get rid of this bad habit as soon as possible.
If you can not sleep without a TV, then set the timer in order to reduce the consequences of lack of sleep.
