Normal sleep

Sleep is important for children's learning and behaviour. Sleep helps to restore physical and mental health and keep our memory and infection-fighting (immune) system on track. Sleep also helps children's brains grow. Children who do not get enough sleep may not be able to learn as well as their school friends who get enough sleep. Sleep is also important for teenagers - they need an average of 9 hours of sleep each night.
