Getting Six Hours of Sleep Can Be Just as Bad as Not Sleeping at All

Not getting enough sleep is detrimental to both your health and productivity. Yawn. We’ve heard it all before. But results from one study impress just how bad a cumulative lack of sleep can be on performance. Subjects in a lab-based sleep study who were allowed to get only six hours of sleep a night for two weeks straight functioned as poorly as those who were forced to stay awake for two days straight. The kicker is the people who slept six hours per night thought they were doing just fine.

The sample size is way too low to take the news seriously, but for a follow-up study? I’d be curious to know how people do when they routinely get 4-6 hours of sleep during the week, but then catch up by sleeping 8-10 on the weekend.

It seems that since the people sleeping 6 hours per night didn’t show really ill effect until 10 days in, that being able to “reset” once or twice per week might make a real difference.  I know I’ve had times where I’m suddenly aware that I’m quite tired, go for a nap to find I’ve been out for hours.
