Sleeping in on weekends may extend your life

Researchers say you shouldn't feel guilty about catching up on your Z's.

People who only get less than five hours of sleep a night throughout the week, but then have a longer snooze on the weekends, had no heightened mortality risk.

Individuals in the study who slept for fewer than 5 hours per night during the week faced a 52% higher mortality rate; however, those who could get an extra two hours of sleep on the weekends lived just as long as those who consistently slept 7 hours a night during the week.

"The results imply that short (weekday) sleep is not a risk factor for mortality if it is combined with a medium or long weekend sleep", the researchers wrote in the study.

However, people who slept for eight or more hours, seven days a week, were found to have a 25 per cent higher mortality rate compared with those who kept to six or seven hours a day. That was true only for those under 65; the mortality difference disappeared for people who were older. "Well, you can, but you won't live as long". They might sleep six hours or slightly less. "This suggests that short weekday sleep may be compensated for during the weekend, and that this has implications for mortality".
