Why this matters so much is that sleep deprivation is associated with poorer health - we are at increased risk of high blood pressure, stroke, obesity, depression and cognitive decline. It also has a huge impact on our performance that can cost us dearly. At the societal level, sleep disorders cost the Australian economy over $5.1 billion dollars in 2012 with the reduction in life quality costing a further $34.4 billion dollars a year.
