If you're trying to make up for reduced sleep by getting in a few extra hours over the weekend, you may not be doing enough to fix the problem.
We've posted that catching up on sleep during the weekend can and can't help, but it really comes down to the numbers. A recent study published in the journal Sleep suggests that regularly reduced sleep (i.e. less than eight hours) can't be made up by getting just a little extra rest on the weekend. Even worse, your body has a physical difficulty even allowing you to get that additional rest because your sleep patterns are uneven.
[T] he body's circadian rhythm will probably prevent a lot of people from even getting 10 hours. So if you are counting on a single night's sleep to do a full recharge after a long hard week think again.
While not necessarily surprising, the findings demonstrate how vital regular full sleep when recovery isn't as simple as we may have thought.
If you sleep less than 6 hours per night for 2 weeks your performance will be like you didn't sleep for 2 days.
The researchers of this study recommend cutting back on TV to find extra time to sleep, but if that's not enough you may need to reconsider your day-to-day choices. The effects of sleep deprivation can be dramatic, such as doubling your risk of heart disease. Consider getting sleep when you're supposed to, as you may have to put in a bit more time than you thought to make it up.
