Chances are you’ve been staring at your computer screen for hours already. If not, then you may later on today. Have you ever considered how much TV and computer screen time we expose ourselves to? Often children are exposed to many more hours of screen time than recommended; the Consortium to Lower Obesity in Chicago Children recommends no more than two hours of screen time daily. Stipulations of this sort are part and parcel of the campaign to lower rates of overweight children and obesity in adolescents. (Overweight is generally used for children and adolescents ages 2-20, while obesity is used for adults 21 and older).
