Today, more and more kids use some kind of an electric device, whether it’s a smartphone, a tablet, a game console, or a TV. But do you know how that affects their sleep?

Some new studies have shown that teenagers who spend hours in front of an electronic device, such as: a cell phone, a tablet, a computer, a game console, or a TV, have more problems sleeping at night.

According to one study, no matter the period of the day when the teen is watching TV or something else, it will affect how long he sleep. The reality is – the longer they pass in front of a screen, the shorter their sleep will be.

A study showed that boys and girls have different preferences when it comes to the types of devices. In reality, girls spend more time with their smartphones and MP3 music players, whereas boys with their game consoles. Actually, teenagers who use electronic device before going to bed, need more than one hour to fall asleep.

The teenagers who use electronic devices for more than 4 hours a day are 49% more likely to need longer than one hour to fall asleep, in comparison to those who use it less than 4 hours a day.

Normally, to feel well rested, teens need 8 to 9 hours of sleep.

It’s still not clear why screen disrupts sleep, but one possibility is that the light from the used electronic device might interfere with the body’s internal clock, which controls the circadian rhythm. Another possibility is that the device may simulate the nervous system, which makes it, again, difficult to fall asleep.

It’s very important that the parents make some rules and be good role models when it comes to the usage of media. They should restrict media use, both during the day and at night, in order to ensure their teens a good night sleep.
