What is sedentary behaviour and how common is it?

Sedentary behaviour refers to any waking activity characterised by low energy expenditure and a sitting or reclining posture. Common sedentary behaviours include sitting while watching television, driving a car or working at your computer.

We at BeUpstanding™ can see the potential in reducing sitting in Australian workplaces to improve health outcomes, as well as overall wellbeing, for a healthier, happier workforce.

In a new paper, we explore how prolonged sitting may affect the brain’s fuel supply and have a negative impact on brain health. The brain is a glucose hungry organ. It weighs about 2% of body mass but demands about 20% of our resting energy requirements, which is mostly in the form of glucose, the primary brain fuel. If this energy supply is disrupted it can impair and even damage brain cells. Therefore, the availability of glucose to brain cells may have implications for brain health. Exposure of the brain to both high glucose levels and low glucose levels can increase the risk of developing dementia. Also, switching between a…
