A June 2019 study by Columbia University finds that, “…leisure-time sitting (while watching TV)--but not sitting at work--was associated with a greater risk of heart disease and death among the study's more than 3,500 participants. The study also found that moderate-to-vigorous exercise may reduce or eliminate the harmful effects of sedentary television watching.”
Dr Keith Diaz said, “Our findings show that how you spend your time outside of work may matter more when it comes to heart health … Even if you have a job that requires you to sit for long periods of time, replacing the time you spend sitting at home with strenuous exercise could reduce your risk of heart disease and death."
