Electronic devices should be avoided 1 hour before bed

Surveys conducted by the US National Sleep Foundation show that about 95% of Americans use electronic devices within an hour before bedtime. In 2013, the fund found that 89% of adults and 75% of children had at least one electronic device in their bedroom, mostly TVs, mp3 players, tablets or smartphones. .

>>>The harmful effects of artificial light

According to experts, technology products ruin your sleep in many ways . First, the light and noise emitted by these devices can interrupt the sleep cycle and alter sleep-related hormone levels.

Light from the screen can cause the body to think it is daytime, preventing the production of melatonin - a hormone that helps regulate sleep. Next, online newsletters as well as video games can make your brain stay awake, making it hard to relax and fall asleep.

Experts said that when in open mode, mobile phones continuously transmit information to cell towers, emitting radiation. Research has shown that people who are exposed to mobile phone radiation 3 hours before sleep will be very sleepy and do not sleep deeply. In addition, recent studies have found that children who own electronic devices in bedrooms will sleep less and sleep quality is lower than other children.

So to protect sleep - a mechanism that helps the body recover and renew energy for work and study - experts recommend having a "curfew" in the bedroom. It is an hour before bed, stay away or turn off all technology equipment.
