A study conducted by the University of Haifa and Jezreel Valley College in Israel has found that kids who have a television or computer in their room sleep less than children who do not.
Researchers followed 444 middle school children. They found the average bedtime was 11:04 p.m. and usually woke up around 6:45 a.m. Children who had a television or computer in their room on average when to sleep 30 minutes later. They also spent an hour more than the other children watching television or using the computer.
Adults these days may not remember their parents telling them to turn their televisions or computers off before bed but they are probably finding themselves handing that advice to their children.
