Sitting for eight hours a day increases the risk of stroke


According to a new study, adults under the age of 60 who spend most of their day sitting have a higher risk of stroke than those who spend more time with physical activity.

For those who sat for eight or more hours a day and were not otherwise very physically active, was seven times more likely to have a stroke, than those who spent less than four hours sitting and exercising for at least 10 minutes a day, according to a study published in the American Heart Association’s Stroke.

The researchers analyzed health data from 143,000 adults in the Canadian Community Health Survey. Participants 40 years of age and older who had not had a previous stroke were followed for an average of 9.4 years. “Sedentary work is thought to impair glucose and lipid metabolism, blood flow, and increase the risk of developing inflammation in the body. These changes can have a detrimental effect on blood vessels over time and increase the risk of heart attack and stroke, ”explained the lead author of the study. Raed Joundi, researcher at McMaster University in Ontario, Canada.

Of the participants in the study, 2,965 people developed stroke. Ninety percent received ischemic stroke during the study period. This is the most common type of stroke, Joundi said, which occurs when an artery that supplies blood to the brain becomes blocked. If the stroke is not treated quickly, the brain cells in that area may die due to a lack of oxygen, he added.

There are several signs that someone has had a stroke: common symptoms include a feeling of weakness in the arms, legs or face, especially a warning sign if the feeling is limited to one side of the body. But blurred speech and vision or hearing problems, as well as severe headaches unrelated to other health problems, may also indicate stroke, said Kerry Stewart, a professor at Johns Hopkins Medical University in Maryland who did not participate in the study.

According to the professor, increasing physical activity and reducing time spent sitting can help reduce the risk of stroke. According to his advice, you can start by standing more and sitting less and, for example, climbing stairs instead of the elevator.

According to the recommendations of the American Association of Cardiologists, adults should perform at least 150 minutes of moderate-intensity physical activity per week. According to Joundi, it is ideal if this movement takes place over periods longer than 10 minutes. “Activities can be considered moderate in intensity if your heart rate rises enough and you sweat, such as walking or cycling.” – He told.

Previous research has shown that 10 potentially excluded risk factors, including alcohol consumption, can be associated with 90 percent of the development of strokes. According to Joundi 90 percent of strokes could theoretically be avoided if all these risk factors in a given population were excluded.

Increasing physical activity is just one of the important components reducing the risk of stroke, cardinal proper diet, quitting smoking, and screening and treating high blood pressure and diabetes, the researcher explained.
