Sleeping In On Weekends Might Help You Live Longer

Sleep expert Michael Grandner explains it this way: Most people who are considered "short sleepers" are probably just shy of getting seven hours.

Also, the point of the study done in Sweden is to point out that it is possible to make up for a sleep deficit, not to lay out the most ideal way to do it.

But a professor from the stress Research Institute at Stockholm University says perhaps short sleepers are catching up on some of the sleep they missed on the other days. The American Academy of Sleep Medicine and Sleep Research Society recommends adults ages 18 to 60 sleep about seven hours per night. For under-65s, they found while sleeping fewer than five hours a night increased mortality by 52 percent, the increased chance of death could be wiped out by getting the right amount once or twice a week. What is your average amount of sleep per week?

But before you cancel tomorrow's pre-breakfast workout in favour of some more bed time, it should also be noted that there were some limitations to the study, namely that participants were asked to recall their sleep patterns rather than being actually observed sleeping.

For people over 65-years-old there is no link between sleep duration and a heightened risk of death.

So when Saturday morning rolls around, go ahead and turn off your alarm clock - it's for your own good. If you don't get enough sleep, you wake up with that sleep pressure and start the day with a higher need for it.

He thinks a lot of people may relate to sleeping less during the week and, at the very least, may want to have an excuse for sleeping in on their days off. "People can not learn to live on insufficient sleep and they may not be aware of their reduced cognitive abilities".
