Sitting for more than 8 hours could cause a stroke …

People who reported sitting eight hours or more a day and were not very physically active, were otherwise seven times more at risk of suffering a stroke than people who spent less than four hours being sedentary and at least 10 minutes exercising each day, according to a study published. in Stroke from the American Heart Association.

The researchers included the health information of 143,000 adults from the Canadian Community Health Survey in their analysis. The scientists followed the participants, who were 40 and older with no history of stroke, for an average of 9.4 years.

“Sedentary time is believed to affect glucose, lipid metabolism and blood flow, and increase inflammation in the body.”said the study’s lead author, Dr. Raed Joundi, a clinical scholar at McMaster University in Ontario, Canada. “These changes, over time, can have adverse effects on blood vessels and increase the risk of heart attack and stroke.”.

Of the 2,965 strokes that participants had during the study period, 90% were ischemic strokes. Those are the most common type of stroke, Joundi said, and they occur when an artery that supplies blood to the brain is blocked, he detailed. CNN.
