Most of us know watching too much TV isn’t good for us–but exactly how bad is it?
New research shows its effects on the heart are dangerous, and sometimes irreversible.
In one study, researchers grouped participants into 3 groups based on their TV watch time, ranging from 7 to 21 hours.
They then carefully examined their health for any signs of cardiovascular disease.
Those who watched more than 21 hours of TV per week were nearly 50 percent more likely to have plaque buildup in their arteries, something that could lead to atherosclerosis.
Atherosclerosis, if left untreated, could lead to a heart attack.
In addition, they were 68 percent more likely to develop high blood pressure, a common risk factor for heart failure.
So vegging out on the couch definitely isn’t healthy; if you’re spending at least 3 hours a day doing so, it could serious ramifications.
To cut your risk, limit your TV time–and switch to more active habits instead, such as playing sports, walking more often, or just engaging in more outdoor activities.
