Want your kids to sleep better at night? Turn off the TV. That's the conclusion of a new study from Finland showing that merely having a television on in the house，even if the kids aren't actively watching it，can be enough to disturb their sleep patterns significantly.
Childcare specialists are very specific about the amount of hours children of a given age should spend in front of the television and the kinds of shows they should be watching. But few people have looked closely at what happens when a TV is simply on in the background - either being watched by an adult or， just as monly， by no one at all.
In a study published in the Journal of Sleep Research， Finnish investigators tried to get at that question， surveying 321 parents of 5-and 6-year-old children to determine the families' viewing patterns and the effect this had on the kids' sleep habits.
All of the families in the study watched a pretty fair amount of TV，with at least one television in the house switched on for an average of 4.2 hrs. per day. On average a child actively watched TV for 1. 4 of those houre and was passively exposed to TV for at  least another 1. 4 hrs. In 21 % of the homes，the kids had a TV of their own in the bedroom.
All that exposure，it turns out. was doing the kids' sleep patterns no favors. In general,
    hours of passive or active viewing was. the more problems young children had falling asleep. staying asleep，waking up in the morning and avoiding fatigue during the day.
But not all TV viewing was equal. Watching TV alone or at bedtime had greater negative impact on sleep. Unusually high passive exposure - 2. 1 hrs. per day or more - was particularly associated with sleep disturbances. especially when they were adult shows to which the kids were exposed.
