How harm arises from sedentary work
The harm associated with prolonged occupational sitting is likely due to insufficient dynamic muscle activity, insufficient energy expenditure, insufficient movement, lack of postural variety, and diminished gravitational resistance.
What is considered excessive work related exposure?
Occupational sitting is common among workers, with one half of workers reporting sitting often or all of the time at work. Exposure to occupational sitting occurs across different industries and occupations.
There is no clear definition of excessive occupational sitting exposure. However, sitting for longer than 30 minutes without a mini-break, and sitting all day at work (being “too busy” to take a break) are likely to be detrimental to health. To date, assessment of occupational exposure has largely been focussed on office work environments, with limited evidence for exposure or interventions in non-office environments.
Ways to reduce prolonged sitting at work
A range of initiatives has been proposed to reduce prolonged sitting at work, including simple interventions that interrupt prolonged occupational sitting by substituting sitting with non-sedentary tasks, such as:
· Switching to work on a computer at a standing workstation
· Standing to read a document
· Having a standing or walking meeting
· Standing while talking on the phone
· Walking to deliver a message to a colleague rather than emailing
In essence, employers and workers should aim for small and frequent changes from sitting as much as possible and less time sitting in total.
