Sleeping in on the weekend may make up for less sleep during the week.

Most of us don't get as much sleep as we should, which is often due to hectic weekday schedules. Åkerstedt et al. reveal that all is not lost—sleeping in on the weekends may have beneficial effects on our health. In a 13-year study of more than 43,000 subjects, the researchers compared the duration of sleep on weekdays versus weekends with overall mortality. Individuals (<65 years old) who caught less than 5 hours of sleep a night had a higher death rate than those that regularly had 7 hours of sleep. But when the weekday short sleepers compensated with long sleep on weekends, no difference in mortality was observed.
