Ah smartphones! On the health side, we must recognize that they are very useful: they allow us to avoid back pain, they slow down the onset of Alzheimer’s disease, they measure our pulse and soon they will also allow us to monitor evolution of the growth of the future baby. But smartphones also have a dark side. Not only do they make children and teens addicted, but now a new study tells us that they prevent us from falling asleep easily.
This study published in the professional journal Organizational Behavior and Human Decisions Processes shows that using your smartphone late at night could cause a feeling of exhaustion the next day, making us less focused at work. For this study, 82 executives answered a questionnaire on the use of their smartphone and their ability to concentrate was measured at several times of the day. The researchers found that smartphone use after 9 p.m. was associated with a decrease in sleep during the night. And that this lack of sleep was then associated with great fatigue the next morning.
Oddly enough, smartphones have a greater effect than using a laptop, tablet or television. But that doesn’t surprise Professor Russell Johnson, study researcher and professor of management at Michigan State University because, according to him, “smartphones are almost perfectly designed to disrupt sleep. Indeed, they keep us mentally engaged. in work late at night, making it difficult to pull away from it to relax and fall asleep. “
