Nowadays, more and more people complain that they are not able to get enough sleep at night. This is a very popular problem and those people have all the rights to be concerned about their health. A new study, which the Journal of Sleep Research published, people under the age of 65 who get less than five hours of sleep seven days per week have an increased risk of early death than those who get at least six hours of sleep.
However, the good news is that this lack of sleep can be countered by sleeping a lot during weekends or off days. This study found that people who managed to get more sleep on weekends did not present an increased mortality risk. So, it seems that the effects of sleep deprivation during the week can be fought back by longer lie-ins. According to Torbjörn Åkerstedt, the lead author of the study, how much you sleep matters a lot when it comes to how much you live. Sleep is crucial for longevity. The researchers based their findings on data from over 38,000 adults in Sweden.
More sleep during weekends can decrease the risk of early death
Åkerstedt also explained that in the past, researchers looked at the link between mortality and sleep duration. However, no study focused on sleep over a working week. This is what made him think that surely, there must have been a change if they also took the working week into account. It seems that even if the study did not prove that weekend sleep is actually catch-up sleep, this is their assumption.
It’s also interesting that for people over 65-years old, this correlation between mortality and sleep disappeared. The team thinks that it may be because old people usually get enough sleep. Same goes for children.
