How much do screens and sleep debt affect the mental health of children and adolescents? Canadian researchers * have observed the impulsiveness of youth. That is, "the tendency to look for exhilarating experiences, to overreact to pleasant or unpleasant stimuli, to react impulsively when one is bad or in a good mood," says Dr. Michelle Guerrero, lead author of the study.
As a result, "children and adolescents who do not sleep enough and spend more time than the number of hours recommended in front of a screen are more likely than others to act impulsively and make bad decisions."
The behaviors involved may also be related to "eating disorders, addictive behaviors and substance abuse". Hence the importance of establishing good habits in everyday life: no less than "9 to 11 hours of sleep per night and a maximum of 2 hours per day of leisure time in front of a screen".
Note: in a previous study, Canadian researchers found a risk of delayed development of the small related to exposure to screens.
