You may want to sit down for this one. On second thought, maybe stand.
New research has confirmed just how bad sitting for multiple hours at a time can be (an activity as common as breathing in today's digital age).
The study, which tracked more than 100,000 adults from 21 countries over 10+ years, found that more time spent sitting during the day was tied to serious health risks. Those who regularly sat for eight or more hours a day were found to have a ~20% higher risk of heart disease or dying from any cause, compared to those who only sat for four hours. Prolonged sitters were also ~50% more likely to develop heart failure.
Some factors to consider...
The one-two punch. A combo of prolonged sitting + lack of physical activity was found to be particularly harmful - nearly as bad as smoking.
Lace up your tennies. Getting in more exercise when not sitting offset the risks of prolonged sitting.
Or just...sit less. Those who sat the least had the lowest risk of early death and heart disease.
