Current guidelines for standing and sitting exposures are under
constant review as emerging research provides greater precision.
A recent study suggests that workers should initially aim to
accumulate two hours a day of standing and light activity (light
walking) during working hours, before eventually progressing to
a total accumulation of four hours per day.
Not all workers that sit all day are computer operators. Health

for workers in laboratories and manufacturing environments.
Having the option to stand for activities that require manual force,
repetitive reach or handling that are more awkward when in a sitting
position can potentially reduce the manual task risk of their work.
Workers who need to rotate workstations (or hot desk) can also be
accommodated for (based on their different statures or conditions).
Sit–stand desks are being used to assist workers in managing
acute or chronic spinal conditions, and hip and lower limb
conditions that affect sitting tolerances. They have also opened
up opportunities for those workers who are at risk of losing
their employment due to their reduced functional capacity from
deteriorating medical conditions or chronic diseases. Workers are

in some cases, increase employees’ hours of work.

at hand. Understanding the interaction between the worker and the

Other strategies to promote movement may be more appropriate
than just a sit–stand desk and assessing the individual’s attitude
towards sitting or standing will ensure compliance with recommended
equipment. There are plenty of examples around the country where
sit–stand desks have been installed but are not utilised as they are

professionals, it is our responsibility to ensure people understand
that movement is good for health at work. Following on from this,
we may then have a chance for workers to move outside of work.
If sit–stand desks can be a tool for occupational health
professionals to assist workers to continue safe and durable work,
then we need to support research to develop evidence-based
standards to support our recommendations to employers and
government-funding bodies. Height-adjustable workstations in the
workplace have only been researched since 2009 and now sit–
stand desks are common in many workplaces. There is still much
work to be done on this subject. At least one thing we do know is
that our next posture is our best posture. Keep moving!
