If you are having trouble sleeping, then this other study suggests that you go camping for a weekend in order to reset your body's natural sleep cycle; or you can simply put on Baa Baa Land, the "world's most boring film".
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".
If you love sleeping in on the weekends, you're not alone.
Torbjörn Åkerstedt, a professor and director of the Stress Research Institute at Stockholm University told CNN he was quite surprised by the findings on sleep during off days. This study was not an experiment, Akerstedt emphasized, and these data can not show that short or long sleep is responsible for higher mortality.
However, the effect of short sleeps over a few days may be countered by a later lie-in.
"We also note that the older participants are "well rested" when they wake up, whereas the younger are definitely not 'well rested.' Our interpretation is that sleep need is reduced with increasing age". This peek at weekend slumber fills in an "overlooked" gap in sleep science, Akerstedt said.
Not in the new study.
The study found that individuals younger than 65 who slept for fewer than 5 hours per night the entire week faced a 52% higher mortality rate.
But channeling your inner cat and sleeping too much can be just as bad for your health, studies have found. "If you eat OK during the week and you splurge a little on the weekend, you probably aren't hurting your health, but if you eat crap all week, no amount of Brussels sprouts or kale that you eat on the weekends can make up for that", he said. "Perhaps it's giving them hope that this habit is in some way good for them".
