The research is clear—long periods of sitting have serious health consequences
Why is too much sitting bad for us
When you sit, you are spending very little energy and your large postural muscles aren’t working very hard
When you stand, your muscles are working 2 ½ times harder than when you were sitting
When you move, you are burning 3 times more energy than when you were sitting
What are the risks of too much sitting?
High levels of sitting increases the risk of type 2 diabetes, cardiovascular disease and musculoskeletal disorders
High levels of sitting is linked to some cancers, and workers who have been in sedentary roles for more than 10 years have double the risk of colon cancer
Reduced sitting time promotes better health, which can improve productivity, lessen the chance of injury at work and reduce sick days
People who sit for more than 11 hours a day have a 40% increased risk of death in the next 3 years compared with people who sit for less than 4 hours

So how much sitting is too much?
Researchers are still working that out.
Currently, guidelines recommend that we minimise the amount of time spent in prolonged sitting and break up long periods of sitting as often as possible
At BeUpstanding, we suggest you aim to:
50% or less
of your work day sitting
Avoid prolonged periods of sitting – aim to get up at least
every 30 mins
The average desk-based worker sits for over three-quarters of their workday
Even if you exercise regularly, if you spend the majority of the rest of your day sitting, you are at risk
You don’t have to stand all the time
It’s continuous periods of sitting
(of more than 30 minutes) that are harmful
Taking short, regular breaks
from sitting can be beneficial for health
The next posture is the best posture
It’s important to mix things up.
The research shows workers should aim
for a rainbow throughout the day
