Adolescents who regularly slept for five to seven hours during school nights at baseline and who got 71 minutes of additional nightly sleep on average for two weeks spent 52 fewer minutes daily on average in sedentary activities, researchers reported in Sleep Medicine. The findings also showed that additional sleep didn’t significantly change the time teens spent on light or vigorous physical activity.
