Sleep Time is replaced by Screen Time

Now a day’s many teenagers are replacing their much time for screen instead of sleep according to a new study. It has been analyzed by the survey data by Arya College of Engineering and IT which collected from hundreds of thousands of adolescents and the result has been shown by them that the share of teens who are losing more sleep and logging more screen time raised dramatically in past few years. According to many experts the teenagers need about nine hours of sleep a night from age 12 to 17. Their body and mind suffer when teens do not get enough shut eye.

Lack of sleep may cause many problems like depression, anxiety, poor performance in schools and obesity as well. Over time in teenagers’ online activity and sleep patterns, the researchers scouted for changes and each student has been asked about their sleep habits. More than 4 in every 10 adolescent were found fewer hours of sleep than requirement due to the boom of video-Conferencing. That is at least two hours less then experts recommend. Researchers and his team have been concluded that something should be done with the problem of smart phone which is causing diminished sleep in teenagers.

The researchers now noticed that the teenagers are increasingly foregoing sleep for texting, using social media or watching videos on their phone. Teenagers who have been used electronic devices for at least five hours in a day were found more likely not to get enough sleep comparison to those who spent only an hour a day on such devices. The team of experts has also looked for that whether watching T.V. or homework or after school jobs were linked to falling sleep time and none of these were appeared to make any difference.

According to the study by B Tech Electronics and Communications Engineering, the light which emitted by the screens can interfere with the body’s natural sleep and wake up rhythms as cell phones, tablets and computers give off all colors of light. But the light in the blue portion of the color spectrum tricks the brain into thinking it is still day time. At the time of bed using phones is a problem. The brain needs about one hour to become sleepy when students turn their devices off to go to sleep.

There is night shift mode in some phones that reduces the blue light in order to emit their screens but that change is not enough to erase the effects of late exposures to their screens.
