How long do you sleep on any given night during the workweek? Maybe you're one of the lucky ones who enjoys the full 7+ hours of recommended sleep, but if you don't fall into that category you may want to consider pushing your Saturday morning plans back a bit.
As with any study, the one I'm about to discuss shouldn't be taken as a definitive end-all be-all finding. While sleep deprivation can have some severe long term effects, it isn't the only thing that impacts your lifespan.
The Washington Post featured a study by the Stress Research Institute at Stockholm University of 38,000 people that had some fascinating findings regarding lack-of-sleep. Here are some of the key ones worth discussing:
- As you might imagine, getting less than 5 hours of sleep a night (adults 65 and younger) every night died at an earlier age than those who slept 7 hours each night.
- However, the study also showed that those who slept 5 hours on weeknights then slept in on weekends lived as long on average as the 7 hour a night group.
While the study's results are plausible, the Washington Post reached out to another sleep expert who admitted as much, but also cautioned that sleep itself cannot be banked up to use when later when we don't have enough time to get a full night's rest.
What do you think? Generally, I feel much better DAYS after sleeping in for a weekend, even if I've gone back to my weekday sleep schedule.
