Lots of children are not getting enough rest and not sleeping properly because of technology - according to a new study by education experts in America.

It says that in some countries as many as two thirds of 9 and 10-year-olds are being kept awake because of things like mobile phones, consoles and computers.

The international survey by Boston College, says lack of proper sleep can have an impact on children's education as kids might find it more difficult to concentrate if they are tired.
