According to sleep specialists an increasing number of people are sleeping less than 5-6 hours a night, which could make them prone to health, risks like diabetes and other chronic illnesses.
The survey was conducted by scientists from the Woolcock Institute in Sydney on some 3300 NSW residents and found that about one in five persons suffered from chronic sleep restrictions.
Over 10 per cent suffered from chronic daytime sleepiness while more than 30 per cent suffered from insomnia or some other sleeping disorder.
People slept an average of 3 to 7 hours during the week and 5 to 7 hours on the weekend. However what researchers found most worrisome were numbers showing that about 18 per cent of adults slept less than 5 to 6 hours a night and that it was people in their 30's and 40's who were most losing out on sleep.
Co-author of the study, Dr Nat Marshall concluded that such findings were alarming especially following a US study, which found that people sleeping less were more prone to diabetes and obesity.
