Q: What are the risks of sitting too much?
A: Researchers have linked sitting for long periods of time with a number of health concerns, including obesity and metabolic syndrome — a cluster of conditions that includes increased blood pressure, high blood sugar, excess body fat around the waist and abnormal cholesterol levels. Too much sitting also seems to increase the risk of death from cardiovascular disease and cancer.
One recent study compared adults who spent less than two hours a day in front of the TV or other screen-based entertainment with those who logged more than four hours a day of recreational screen time. Those with greater screen time had a nearly 50-percent increased risk of death from any cause. They also had approximately a 125-percent increased risk of events associated with cardiovascular disease, such as chest pain or heart attack
The increased risk was separate from other traditional risk factors for cardiovascular disease, such as smoking or high blood pressure. Any extended sitting — such as behind a desk at work or behind the wheel — can be harmful. What's more, spending a few hours a week at the gym or otherwise engaged in moderate or vigorous activity doesn't seem to significantly offset the risk. Rather, the solution seems to be less sitting and more moving overall.Source: Mayo Clinic
