Ruth Kiely, Vice President of the Irish Society of Chartered Physiotherapists, outlined what people can do to alleviate the effects of sitting down for long periods of their day.
She said: "If they're sitting and their job entails sitting for prolonged periods of time, they must get up and get moving, get active.
"Standing up stretching, moving their printers, going out for a lunchtime walk or walking the dog at home.
"It's really important and it will save them from having chronic disease later on, or the consequences of chronic disease later on in their years."
Sitting is the new smoking, according to physiotherapists.
A survey from Chartered Physiotherapists shows those aged between 18 and 24 are the least active adults.
It also found that those aged over 55 outperform every other age group in the amount of physical activity they do.
The survey revealed young people have too much "screen time" spent in front of TVs, computers and phones.
Almost half of people say they either cannot find the time for exercise or family commitments get in the way.
