Scientists from the UK Data research project told us through research: In different countries around the world, people’s sleep time has only increased or decreased for a few minutes over the decades, and there has been no significant change!
One of the data from the sleep app of 8,000 iPhone users earlier in 2016 showed that the average sleep time of these users was 7 hours and 50 minutes.
Why do modern people always feel that they are not getting enough sleep? Scientists believe that the most likely explanation is that the increase in work makes us need more sleep to rest the brain.
Therefore, it is a good choice to sleep late on weekends and supplement your unmet sleep needs during workdays!
