Researchers say you shouldn't feel guilty about catching up on your Z's.
How much sleep do you get during the week versus the weekend?
Those who enjoyed eight hours of sleep during the week and weekend were found to have a lower mortality rate meaning they lived longer.
"Possibly, long weekend sleep may compensate for short weekday sleep", researchers said.
However, people who slept for eight or more hours, seven days a week, were found to have a 25 per cent higher mortality rate compared with those who kept to six or seven hours a day.
Curiously, after the age of 65, there is no relationship between sleep duration and mortality. The latest study, published last week in the Journal of Sleep Research, address the association of both weekday and weekend sleep duration with overall mortality.
And could even help you live longer. What is your average amount of sleep per week? They might sleep six hours or slightly less. He was not involved in the new study. This study was not an experiment, Akerstedt emphasized, and these data can not show that short or long sleep is responsible for higher mortality.
This study relied on people to describe their own sleep habits, which can generate a "mish-mosh", in Lauderdale's view, of "accurate and less accurate information".
There are few things in life more satisfying than crawling into bed on Friday night knowing you'll get a well-deserved lie-on in the morning. 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. The performance of sleep-deprived individuals was no different among those who reported feeling alert and those who said they felt exhausted.
