Even if you exercise regularly, it might not be enough to counteract the effects of too much sitting.
Many people have sedentary jobs and also engage in sedentary leisure activities after work, with the result that a lot more time is spent sitting than moving. A study calculated how much time a group of men spent sitting during an average day, and found that those who sat during the day were substantially more likely to die of heart disease.
According to NPR:
“Specifically … men who reported more than 23 hours a week of sedentary activity had a 64 percent greater risk of dying from heart disease than those who reported less than 11 hours a week of sedentary activity. And many of these men routinely exercised … [S]cientists are just beginning to learn about the risks of a mostly sedentary day.”
