Surveys say American children on average get their first mobile phone at the age of 10. Not surprising. This everyday gadget seems amazing. It provides entertainment, communication, information, and companionship. But the phone has its downsides. It affects the part of the brain that activates the visual center. Users see but don’t think. It doesn’t stimulate the frontal lobe, which activates thinking, creativity, attention, decision-making, and problem-solving. And the brain is like a muscle: when it is not in use, it grows weak. The effects of digital devices occur in other parts of the body as well — melatonin production, which affects sleep; cortisol production, which affects mood; oxygen intake and muscular development, which are limited from bending the head down for extended periods to look at a screen; and impaired eyesight. Not to mention effects from radiofrequency radiation exposure like miscarriage, brain cell reduction, and increases in rectal and breast cancer, among others.
