Study suggests short sleep during the week can be compensated by sleeping more on weekends
Sleep duration and mortality: can we compensate for lack of sleep on weekends? - science news in brief

A new study analyzed the relationship between the duration of sleep during weekdays and weekends and mortality rates. For people below 65 years of age, the study found that short sleep during weekends (< 5 hours) was associated with higher risk of mortality. However, the mortality rate returned to normal values in those people that were sleeping fewer hours during weekdays but had longer sleep on the weekends. So, it turns out we might be able to recover for those lost hours of sleep on weekends, after all! Interestingly, no correlations were found between the duration of sleep and mortality in people over 65 years.
