Heller said there are simple ways to add more physical activity into the day, such as the following:
- Standing up when talking on the phone.
- Marching in place when watching TV -- at least during the commercials.
- Getting up from your desk every hour and doing jumping jacks, knee lifts or knee bends for three to five minutes.
- Climbing a flight of stairs every few hours.
- Vacuuming the house.
- Mopping the floor.
Another expert described the physical fallout of being sedentary.
Dr. Gregg Fonarow, a professor of cardiology at the University of California, Los Angeles, said sitting for too long may have adverse effects including burning fewer calories, and increasing insulin resistance and fats in the blood.
"Greater time spent in non-exercise physical activities can potentially counter these effects," Fonarow said. "These findings further emphasize the importance of decreasing sedentary time and encouraging everyday regular non-exercise physical activity to improve cardiovascular health."
Although the study found an association between being active around the house and reduced heart risk, it did not establish a cause-and-effect relationship.
