Is your teen getting enough sleep?

A school in Northumberland is taking part in a study looking at whether teenagers are getting enough sleep at night.

'Teensleep' is a study of sleeping patterns involving 32,000 pupils in 100 British schools.

It's led by scientists at Oxford, who warn many teenagers now consider their normal bedtime to be after midnight and are risking academic futures because of a lack of sleep.

Schools involved will be divided into groups, with some trialling 10am starts for pupils and others offering lessons in sleep education.

The aim is to improve both exam results and mental health.
