According to a new study, it is good to sleep in during the weekend if you happen to sleep too little during the week.

Are you one of those who likes to sleep in during the weekend? Perhaps you have had a tough week, and then try to make up for it at the weekend with a lie-in. Then, you can now continue to do so without a bad conscience about doing so. Since it is actually good to sleep in during the weekend according to a new study.

The study finds that we can, indeed, compensate for lack of sleep during the weekend. The study included 43,000 people in Sweden. The researchers wanted to find out how age affects sleep duration and longevity.

It turned out that the younger people up to the age of 65 were most affected by sleep length. For example, the researchers noticed that those who slept less than five hours each night, and over eight hours per night, both had an increased risk of dying.

The results showed that people who slept less than five hours a night, or more than 8 hours a night, had much higher rates of mortality than those who slept more. The cause of the correlations is yet to be established.

However, the researchers could see that there was a way to counteract the increased mortality rate. Those who lacked sufficient amount of sleep during the week but slept in during the weekend reduced the risk of dying. This simply means that you can sleep in on Saturday and Sunday morning with a good conscience.

“It seems like you actually can compensate by catching up on sleep during weekends,”

“This is in effect an argument for lazing around all weekend. There probably is an upper limit, but it’s anyway better to increase [sleep hours] on the weekend rather than not doing it at all.”

To note though is that the new study doesn’t recommend to always lying in at the weekend, as results also suggested too much sleep can increase the risk of death too.

The study from Stockholm University in Sweden has been published in the journal Sleep.
