Just one day of work per week is the most "effective dose" for a mental health boost, according to University of Cambridge research.
A study suggests that the risk of mental health problems reduces by 30 percent when people move from unemployment or stay-at-home parenting into paid work of eight hours or less per week.
However, researchers at the universities of Cambridge and Salford found no evidence that working any more than eight hours gives further boosts to wellbeing.
The researchers suggested creative policy options, including five-day weekends, working just two hours a day, or increasing annual holiday from weeks to months. They even proposed having two months off for every month at work.
