New research shows that it is bad children to watch TV, tablet or mobile phone screens bedtime. Researchers from the University Colorado found that "screen time" sleeping damages children's health. The researchers looked at 60 different studies how screen time affects children. They said: "Of more than five dozen studies looking children aged 5 to 17 the world, 90 per cent have found that more screen time is associated with delayed bedtime, fewer hours of sleep, and poorer sleep quality." Screens are becoming smaller and smaller, so children can look them in bed. More than 75 per cent children in the study had some kind of screen in their bedroom.

Children need a lot more sleep than adults. Pre-school children need 10 13 hours, pre-teens should get nine and 12 hours, and teenagers should be getting eight and 10 hours a night. The researchers highlighted three main reasons how screens affect children's sleep. First, the light screens upsets a child's body clock. The light from screens getting into children's eyes they sleep tricks their body into thinking it is still daytime. Second, children often watch videos things that excite them or interest them. This keeps their brain active, so they take longer to sleep. Finally, when children are watching screens, they are not exercising. Children need physical activity to make them tired.
