A mining company operates in a remote region of Australia. To maximise productivity, the company implements a ‘fly-in, fly-out’ (FIFO) work schedule. Workers spend two weeks at the mine site, working 12-hour shifts that rotate between day and night, followed by one week off at home. Several workers have reported persistent fatigue, difficulty sleeping both at the mine site and during their week off, and a noticeable decline in their overall mood and cognitive function.
a. Identify and describe the specific circadian rhythm sleep disorder most likely affecting these FIFO workers.

In this unit students explore the demand for sleep and the influences of sleep on mental wellbeing. They consider how changes to a person’s sleep-wake cycle can affect psychological functioning. Students explore the concept of mental wellbeing, including social and emotional wellbeing as a multidimensional and holistic framework. They apply a biopsychosocial approach to specific phobia, exploring how biological, psychological and social factors are involved in its development and management. A student-designed scientific investigation involving the generation of primary data related to mental processes and mental wellbeing is undertaken in either Unit 3 or Unit 4 or across both Units 3 and 4, and is assessed in Outcome 3 of this unit.
In this area of study students focus on sleep as a naturally occurring altered state of consciousness and the demands for sleep across the life span. They examine REM and NREM sleep, biological mechanisms of the sleep-wake cycle, and how partial or total sleep deprivation can affect psychological functioning. Students compare the effects of full sleep deprivation with blood alcohol concentration and explore circadian rhythm disorders. They consider ways to improve sleep hygiene and mental wellbeing.
