If to all this we add that we spend almost the same time on the internet as sleeping, this technological obsession begins to become a serious threat to our health.
The so-called 'text neck', which appears because we spend our time looking down with a screen in our hands, puts tension in the upper part of the back. According to New York Spine & Rehab Medicine physician Kenneth Hansraj, dropping the chin more than 60 degrees is equivalent to making the spine support an added 12 kg . Using a tablet for long periods of time can also lead to hand and thumb injuries. Likewise, compulsive playing video games reduces sensitivity to pain, which means that we could be hurting ourselves without realizing it. The solution? Raise your head from the screen and rest regularly.
Of course, other problems are more subtle. As the screens of our devices are important emitters of blue light, they inhibit the production of melatonin, a fundamental hormone that, among other things, tells our body to go to sleep. Without this hormone in the blood, our body does not know that it should rest. That is why it is not good to go to bed with a tablet in your hands. Various studies have found that reading a book on an iPad for 4 hours before bed not only delays the secretion of melatonin by an hour and a half, but also reduces the quality of sleep and makes you feel more tired the next day. Then if you are one of those who like to read something before bed, you have to go back to the classic book.
