Sleep health New South Wales: chronic sleep restriction and daytime sleepiness

Abstract

In New South Wales almost one-fifth of the people are chronically sleep restricted and 11.7% are chronically sleepy. Chronic sleepiness was most commonly associated with voluntarily short sleep durations and symptoms of insomnia and depression. If the experimentally observed health effects of sleep restriction also operate at a population level, this prevalence of chronic sleep restriction is likely to have a significant influence on public health in Australia.
