What is fatigue?
SafeWork Australia defines fatigue as “the mental and/or physical exhaustion that reduces your ability to perform your work safely and effectively”.
According to the Sleep Health Foundation of Australia, adults generally require between 7 and 9 hours a night to feel properly refreshed and function at their best the next day. There are always exceptions to this, including the quality of sleep and how each person responds to less/more. It is not recommended however, for an individual to have less than 6 hours sleep, or more than 11 hours in any one given day.
SafeWork Australia reports that causes of fatigue can be work related, personal or a combination of both. They can also be short term or accumulate over time.
What is Sleep Debt?
Sleep debt is when individuals get less sleep than they need in a day, and they build up their need to sleep. Each extra day without enough sleep increases the debt. It can take several days to recover from a sleep debt. One sleepless night can have similar effects on someone impaired from the use of alcohol.
