It's not good if our children watch TV, tablet, or mobile phone before bedtime. Because that's really bed for children healthy. 90 per cent of the studies found that screen time delays bedtime. It leads to less sleep, and poorer sleep quality.
Children need more sleep than adults. Pre-school children need up to 13 hours, pre-teens up to 12 hours, and teenagers up to ten hours a night. There are several reason why screens affect children's sleep. First, the light from screens upset a child's body clock. Second, videos excite children and keep their brain active, so they take longer to sleep. Last, children are not exercising so they are not tired.
