We spend virtually all our waking day sitting, standing, or shifting. The well being affect of every one in all these could be complicated.

For instance, an excessive amount of standing can result in decrease again issues and even a better danger of coronary heart illness. However sitting for too lengthy and never shifting sufficient can hurt our well being.

Then there are individuals who sit for a lot of hours and likewise get in cheap quantities of bodily exercise. For instance, somebody who has an workplace job however walks to and from work for 20 minutes every method and runs two to a few instances every week simply meets the advisable degree of bodily exercise.

Whereas we all know shifting is healthier than sitting, what is much much less clear is how a lot of an excellent factor (shifting) can offset the harms of a nasty factor (sitting).

That is what we wished to search out out in our examine of virtually 150,000 Australian middle-aged and older adults.

We adopted folks enrolled within the 45 and Up Examine for practically 9 years.

Even round 20-40 minutes of bodily exercise a day – the equal of assembly the bodily exercise pointers of 150 to 300 minutes every week – appeared to eradicate most dangers related to sitting.

For individuals who sat lots, changing sitting with vigorous bodily exercise was higher than changing it with reasonable exercise; and changing sitting with reasonable exercise or strolling was higher than changing it with standing.

What is the take-home message?

Our examine helps the concept sitting and train are two sides of the identical well being “coin”. In different phrases, sufficient bodily exercise can offset the well being dangers of sitting.

Ought to we fear about sitting an excessive amount of? Sure, as a result of sitting takes up worthwhile time we might spend shifting. So an excessive amount of sitting is a crucial a part of the bodily inactivity drawback.


We additionally know solely a minority of adults get sufficient bodily exercise to offset the dangers of sitting.

Additionally, many wouldn’t have the motivation to energy by means of a strenuous exercise when they’re juggling many different life challenges.

There are not any identified cures to an absence of time or low motivation. So, maybe we have to add new approaches, past exercising and enjoying sport for leisure, to the “menu” of bodily exercise choices.

Incidental bodily exercise like energetic transportation – suppose strolling quick or biking half or all the strategy to work – or taking stairs are nice methods to turn into or keep energetic with out taking a lot further time.The Conversation
