Australian Unity wellbeing Index has shown the simple way to be happy which is to ensure one regularly sleeps well at night.
The Australian Unity Wellbeing Index revealed that those who sleep for less than six hours a night portrayed lower well being levels as compared to those who slept for seven to nine hours..
The survey of 2000 Australians also showed how too much of anything is too bad and how levels of satisfaction fell when people slept for more than 10 hours a night.
"Sleep closely correlates to people's overall wellbeing," said lead author Robert Cummins, head of Deakin University's Australian Centre on Quality of Life.
"Those who sleep six hours a night report significantly lower levels of satisfaction with their health and safety, which are linked to higher anxiety. This in turn can cause, or be caused by, a lack of sleep. Bringing this to light might encourage people to flick off the light switch or put down the remote control a little earlier," Professor Cummins said.
