There was a conventional thinking that technical gadgets such as computers and mobiles reduce sleeping in people. Some researchers in recent time claimed that mobile, computer and other technological devices are nothing to do with our sleeping duration.

But a recent study conducted by a researcher team at the University of Sydney has emphasized on the belief. The aforementioned researcher team in a journal titled `Medical Journal of Australia` delivered huge support to the belief by disclosing the report of decreasing sleeping duration of Australian people during last some years.  The mentioned the info chart of the Australian Bureau of Statistics which showed that Australian people slept 8 hours and 20 minutes in the year 1992. In the year 1997 the average duration of sleeping of Australian people rose to 8 hours and 33 minutes. In the year 2006 the duration of sleep among them reduced to 8 hours and 30 minutes in average.

After studying the records the researchers did not find any significant difference between the records of the three years. They did not find much difference between the records. That is why they started to think over the belief.
They found that people who were of 65 years age or over experienced 12 minutes less sleep than in 1992. Unemployed people experienced 17 minutes less sleep than they did in 1992 while male carers experienced 31 minutes less than they did in 1992. But the average sleeping duration remained same.

The researchers have also mentioned that less sleeping may lead us to many serious health problems including cardiovascular diseases, obesity, overweight, accident, mental disbalance and injury. They have also mentioned that we should be aware of the serious affects of sleeping disorder. According to them we should be aware of the growing effects of technological devices on our sleeping habit.
