Lack of sleep has been linked to a whole host of health problems, including weight gain and heart disease. However, many of us believe that it is OK to sacrifice sleep during the week so long as we have a ‘catch up’ sleep at the weekend. Sadly, this may not be the case. In a study led by a sleep expert at the University of Pennsylvania School of Medicine, participants were restricted to just four hours’ sleep for five nights and then given a “recovery” sleep of 10 hours. Even after this sleep their reaction times, attention span and levels of fatigue failed to return to normal, showing that a single weekend lie-in may not be sufficient to make up for the effects of lack of sleep during the week.
