Why Prolonged Sitting Harms Us

by Berkeley Wellness  

Spending long hours sitting may increase the risk of cardiovascular disease, and a new study suggests a likely mechanism: Being sedentary increases the accumulation of calcium in arterial plaque, which is a marker for elevated coronary risk.

Researchers analyzed data from 2,030 people without known cardiovascular disease (average age 50), and found that the longer they sat every day, the higher their coronary calcium score—regardless of how much exercise they got or their other risk factors, such as undesirable cholesterol levels or hypertension.

It’s known that prolonged sitting has many adverse effects, notably on blood vessel function, cholesterol, triglycerides, and blood sugar. “Reducing daily ‘sitting time’ by even 1 to 2 hours per day could have a significant and positive impact on future cardiovascular health,” concluded the new study, which was published in the Journal of the American College of Cardiology: Cardiovascular Imaging.
