Study: TV Before Bed Results in Less Sleep

Many parents plop their kids in front of the TV at night to quiet their active bodies before bed. But it turns out this pre-bedtime ritual might actually be making it harder for them to fall asleep. A New Zealand study, published in Pediatrics, adds to the existing evidence that the more television children watch in the evening, the less sleep they get.

The study involved more than 2,000 children and adolescents, tracking the activities participants engaged in during the 90 minutes before bedtime. Researchers then investigated how these correlated to the time it took for the children to fall asleep. All of the children in the sample spent some time watching television during the pre-sleep period. But those who fell asleep later had watched up to 13 more minutes of TV than those who conked out earlier.

Another study conducted by the Seattle Children’s Institute found similar results that watching television shows of any kind after 7pm can cause a 3- to 5-year-old to have trouble falling asleep, have nightmares or feel tired when they wake up.
