Sitting for too long is hazardous to your health

Get out of your chair to engage in outdoor activities: this is the main message of this study, which was conducted among more than 105,000 people in 21 countries.

The results show that people who sit 6-8 hours a day are 12-13% more likely to have early death or cardiovascular disease.

Sitting for more than 8 hours a day is associated with a 20% risk.

These results confirm what we already know, that people who sit longer die earlier and are at higher risk of heart disease. And it’s even more pronounced in low- and middle-income countries.explains one of the co-authors of the study Scott Lear, professor in the Faculty of Health Sciences SFU.


The study, published in the journal JAMA Cardiol, included 105,677 participants between the ages of 35 and 70 and recruited from 1ah January 2003 to August 31, 2021 in 21 countries.

The benefits of physical activity

While sitting for long periods can be detrimental to our health, physical activity can help reduce risk.

The study recommends those who have no choice but to get more physical activity at other times of the day.

Get moving even when working remotely

Jean-François Esculier, physiotherapist and professor at the University of British Columbia (UBC), is not surprised by the results of this study and recalls that physical activity is essential even in teleworking.

He himself works from home with a renovated office equipped with a treadmill.
