We've written a number of posts blaming technology for contributing to insomnia - now it appears that an Australian study wants to debunk this theory.
The outcome of the study suggests that there is no link between cell phone or computer use and insomnia. Instead, the study found that insomnia has a closer relationship with heart problems, obesity, injuries and psychiatric problems.
The study analyzed 14 years worth of data from the Australian Bureau of Statistics collected in 1992, 1997 and 2006. During this period, sleep duration remained roughly constant - the argument is that if cell phones and computer use were to blame for insomnia, we would see sleep duration decline during this period since this is when the two products become more prevalent (and affordable).
That being said, if Australians haven't seen a decline in sleep duration over the past 14 years, why do so many report sleep problems such as insomnia? Perhaps the real issue is sleep quality rather than sleep duration.
