An astounding 81.8% of working hours are spent sitting during a working day.1
Office workers sit for long durations without breaks, longer than 30 mins, or even longer than 55 minutes at a time.2 Uninterrupted sitting for work and school are the main settings for this sedentary behaviour; prolong sitting is also associated with driving, recreational screen time, and sitting during leisure time.
Sedentary behaviour is taken from the Latin word sedere, which means to sit. Sedentary behaviour is characterised by low energy expenditure of less than 1.5 METS.3
Overall, sedentary behaviour accounts for an average accumulation of 39 hours per week for adults, which includes sitting at work, traveling (to work via car, bus, or train then back home), and leisure time.4
“Sitting is a distinct risk factor for major health outcomes, counting premature all-cause and cardiovascular mortality, cardio-metabolic morbidity, and increased risk of type II diabetes.”5
According to the World Health Organisation, “physical inactivity estimated to account for 6% of global deaths.”6
Sit-stand workstation is a height-adjustable desk for computer screens and keyboards, which allows employees the choice to alternate work activity between the usual desk-based sitting position and standing position. The sit-stand workstation intervention will increase physical activity in the workplace and reduce uninterrupted sitting time.
Additionally, a Physiological research published in the Occupational and Environmental Medicine – BMJ Journals “shows that using a sit-stand workstation for 185 minutes, immediately after eating, can reduce post-prandial glucose excursion by 43%”7
After a meal the levels of glucose concentration in the blood changes from before the meal. Those that have type-2 diabetes don’t have optimal glycemia control and are shown to have elevated postprandial (after a meal) glucose concentrations.
Incorporating a sit-stand workstation will encourage better physical health and wellbeing when at work, and when not at work:
“The World Health Organization recommends that adults participate in at least 150 minutes of at least moderate-intensity aerobic physical activity throughout the week to reduce the risk of chronic disease, including cardiovascular disease, type 2 diabetes mellitus, and certain cancers.”6
