The vast majority of articles on SleepBetter.org cover the problems caused by not sleeping enough and the benefits of sleeping better. However, new research indicates that there is a growing population of people out there who are sleeping too much … and it’s not good for them either.
The new study was conducted by researchers at the University of Sydney. It reviewed information from surveys done in 10 countries which asked participants to record how much time they allocated to different tasks in a 24-hour period. The study included surveys from over three decades.
Researchers found that between 1970 and 2007, the percentage of survey participants who reported sleeping for more than nine hours over a 24-hour period increased from 28 percent in 1985 to 37 percent in 2007. What’s more, the percentage of people who slept for less than six hours a night decreased, from about 11 percent in 1985 to 9 percent in 2007.
Studies show that sleeping more than nine hours a night is linked to an increased risk of heart disease, cognitive issues, and other problems.
