A recent study is flying in the face of logic by suggesting that technologies such as smartphones and tablet computers are not keeping us up at night. Tesearchers at the University of Sidney in Australia compared the average hours of sleep for people between the years 1992 and 2006. After looking over all of the data, it was found that there was no significant change in duration of sleep during that time. Overall, the average hours of sleep hovered around 8 hours and 30 minutes for each sample year. This study disproves an earlier poll that said that Australians are sleeping fewer hours than they were a decade ago. Besides the initial findings, it was also revealed that sleeping fewer hours is associated with higher level of education, higher income, longer work hours, and having 2 or more children in the home.
