'Sleep lessons' aim to sharpen up grumpy teenagers

Pupils at schools in Glasgow are being given lessons in how to sleep.

The sessions, run by the charity Sleep Scotland, aim to teach pupils tips such as the importance of a bed-time routine and avoiding late-night television.

Experts say teenagers who seem grumpy and uncommunicative could actually be sleep deprived because they go to bed after midnight - even on week nights.



The advice for pupils is that they should be sleeping for more than nine hours a night.

Researchers found that after going to bed at 2300 or midnight, teenagers were staying awake for hours watching television, playing on games consoles, or browsing the internet.

Some pupils were getting as little as four or five hours sleep a night.
