More than two-thirds of people living in developed countries watch TV before bed, research shows. In one survey, a range of 66% to 80% of respondents in the United States, Canada, United Kingdom, Mexico, Germany and Japan said they regularly watch TV during the hour before sleeping. A study of children age 5 to 18 in New Zealand found that the participants spent an average of 30 of the 90 minutes before bedtime watching TV. Exposure to television before bed is thought to disrupt sleep because the TV light might be overstimulating.
