"Almost All U.S. Teens Falling Short On Sleep, Exercise" - Amy Norton
A new study found that only 5 percent of teenagers were meeting experts' recommendations on three critical health habits: sleep, exercise, and time spent gazing at digital media and television. In general, medical experts say teenagers should get 8 to10 hours of sleep at night, and at least one hour of moderate to vigorous exercise every day. They should also limit their screen time to less than two hours per day. Ariella Silver, PsyD, assistant professor of pediatrics, adolescent medicine, and psychiatry at the Icahn School of Medicine at Mount Sinai who was not involved in the study made this point: the two-hour limit on screen time may be tough for high school students, since their homework may demand a lot of computer time. Dr. Silver also agreed that screen time may hinder teenagers sleep, and social media may be replacing time spent with friend (and the opportunity to be physically active).
