Reduced sleep could lead to mental illness in youth. Internet addiction could be part of the problem, an Australian study reveals.
Young adults who habitually sleep fewer than five hours a night are three times more likely than others to become psychologically distressed. Each hour of sleep lost was linked to a 14 per cent higher risk of distress.
The study surveyed about 20,000 17- to 24-year-olds across New South Wales over a period of 18 months.
Professor Nick Glozier of the George Institute of Global Health, lead author of the study, says they found a very strong association between reduced hours of sleep and mental health problems.
When you get down to the very low levels of hours of sleep like five or six, about 50 per cent of those kids have quite significant mental health problems. That is the first thing.
The second thing and probably the most important is that if you are one of those kids with mental health problems so if you are a adolescent, young adults, then the chances of that health problem becoming chronic and persistent is actually much greater the fewer hours sleep you get.
When Ashley Hall of ABC News asked him whether sleeplessness was a cause of the mental health problems or a symptom, Nick Glozier replied, If you have got mental health problems, it looks like the more sleep you get, the better quality sleep you get, the more likely you are to not have your problem become chronic.
