The 5 harmful effects of the mobile phone on health

Do you remember the days when mobile phones were not taped to our hands yet? This time seems surreal, so much the comfort of these small devices has become indispensable. And the trend should not falter in the coming years: a third of the world's population should be equipped with a smartphone by next year, according to the latest estimates. But spending hours every day on a small screen, fingers stuck on the keyboard, necessarily affect our health.

The eyes

Excessive use of mobile phones and screens in general impacts the lens of the eye and promotes myopia. Even worse, two British women between the ages of 22 and 40 would have suffered a temporary blindness for a few months because of this bad habit. Both were constantly checking their smartphone at night in their bed with one eye, the other being covered by the pillow, as they were on one side. This difference in light caused asymmetry and loss of vision, reports the British daily The Independent. To avoid this problem, be sure to look at the screen with both eyes.

The sleep

One of the effects that have been repeatedly shown is the detrimental effect of blue light on sleep. Because our biological clock is based on light, exposure to screens at night can cause insomnia or difficulty falling asleep. To make sure you sleep well, turn off the electronic devices about an hour and a half before going to bed.

The brain

This is a debate that has been shaking the scientific community for years. The harmfulness of electromagnetic waves and more particularly their possible link with brain cancers has been analyzed by several teams of researchers. The latest study is the National Toxicology Program, an American research program. In the results published at the end of May, scientists say they have observed a significant increase in brain and heart cancers in rats that have been intensely exposed to waves of different powers.

The neck

This problem concerns especially adolescents. Staying curved forward is very bad in times of full growth and can cause neck pain associated with tension or contractures in the neck. Doctors who have noticed an increase in this problem related to poor posture have called it "text-neck".

Fingers

Text addicts may be suspicious of this: the movement of the fingers on the phone keypad can cause tendonitis, especially with the thumb. Just as in the case of the gamepad console, always repeat the same gesture for hours is not good for our fingers.
