On average, we spend more than half of our waking hours sitting down: working at a computer, watching television, traveling in a car, or doing other sedentary things such as reading or chatting with friends. But long stretches of uninterrupted sitting have a range of undesirable effects that may harm your heart, says Dr. Beth Frates, who directs wellness programming for the Stroke Research and Recovery Institute at Harvard-affiliated Spaulding Rehabilitation Hospital.
"Sedentary behavior affects your body in many different ways, even down to the molecular level," she notes.
