An extra hour or two in bed during the weekend halves the risk of depression.

New research has discovered that mental health problems are far less likely in adults who catch up on their sleep on a Saturday or Sunday.

Doctors at Yonsei University in South Korea tracked more than 5,000 men and women who often missed out on a full night's rest during the week and the results - published in the journal Sleep Medicine - revealed that those sleeping for an additional two hours during the weekend were 48 per cent less likely to develop depression.

The study also revealed those with a one-hour lie-in reduced their risk of suffering a low mood by a third.

However, depression rates were 16 per cent higher for people who slept for more than two hours extra on a Saturday or Sunday.
