Presleep Activities and Time of Sleep Onset
Pediatrics published research on a survey completed by 2017 children ages 5-18 regarding activities reported during the 90 minutes before sleep time. The results indicated that television watching was the most commonly reported activity before sleep time. The participants who had a greater engagement in screen time had a later sleep onset. Participants who reported significantly greater time spent in nonscreen sedentary activities and self care had an earlier sleep onset.
