Despite the contradiction staying in bed could see you shed pounds according to new research
Most of us are lucky to get the required seven hours but a study suggests sleeping for more than nine hours a night may help you stay slim.
A study of twins has found a link between sleep and body mass, suggesting people who are genetically programmed to be overweight could counteract their genetic fate spending more hours in bed.
The team from the University of Washington say several genes have been linked to obesity affecting the way the body uses energy and sugar and stores fat.
But the shorter you sleep, the more likely these genes are to have an effect on your body.
‘The results suggest that shorter sleep provides a more permissive environment for the expression of obesity related genes,’ says lead author Dr Nathaniel Watson.
‘Or it may be that extended sleep is protective by suppressing expression of obesity genes.’
Although preliminary, the findings, published in journal Sleep, suggest weight loss is easier when you sleep more.
