Computers and mobile devices are not causing a sleep shortage in adults, according to new research from the University of Sydney.

Using data from the Australian Bureau of Statistics, the researchers found there was no significant change in the sleep duration between 1992 and 2006. This refutes the commonly held view that adults are getting an hour less sleep than a decade ago.
