Sonali investigates how to sleep well

Scientists have done a new study into sleep, and they've found that the more exercise you take during the day, the easier it is to fall asleep at night.

They've calculated that for every hour you sit around, it takes you three minutes longer to get to sleep.

The experts studied 500 7-year-olds and measured how long it took them to nod off, then compared it to how much exercise each kid had taken.

They say that it proves how important it is to stay active.
