For those over 60, spending an hour in front of the TV increases the risk of stroke by 14%

As we age, we naturally slow down, which often means retiring to the couch in front of the TV or with a book. But every hour of sedentary activity between the ages of 60 and 70 increases the risk of stroke by 14% According to a study published in the journal JAMA Network Open.

People who barely moved for 13 hours or more from the day they were awake had it 44% more likely to have a stroke than those who spent less than 11 hours stuck. On the contrary, it was found that doing only 25 minutes of moderate exercise a day, such as brisk walking or cycling, reduces the risk by more than 40%.

Previous research has shown that sedentary lifestyle can cause accumulation of fatty substances in the arteries, what in turn increases the risk of cardiovascular disease. IN physical activity Helps reduce the risk of heart attack by lowering cholesterol and blood pressure and reducing these fat deposits.

Three and a half hours of light exercise a week have been shown to reduce the risk of stroke by 26% compared to less than two hours of exercise (Europa Press).

The experts of San Diego State University installed traffic tracking devices 7607 American men and women s average age 63 years. Participants were asked to wear a thigh-mounted accelerometer that records how much they move and at what intensity in a week. They had to wear it for 16 hours during the day, but they were allowed to take it off for eight hours at night while in bed.

The results were familiar calculate the average time you spend each waking day in a sedentary life, engaging in light physical activity, like a walk around the house, or more intense such as cycling or brisk walking. Sedentary lifestyle is defined as sitting on a chair, lying on a sofa or even standing for a long time.

The researchers analyzed their medical records seven years later, during which they recorded 286 strokes, and discovered this the most sedentary people – who could barely move for 13 hours or more a day – had the highest risk of stroke. they had a 44% more likely to have a stroke within seven years, compared to people who have been stuck for 11 hours or less a day.

Researchers have estimated that every extra hour of sedentary lifestyle increases the risk of stroke by 14%.  But lead author Dr Stephen Hooker said the finding also shows that the risk of stroke can be reduced through exercise (Getty Images).

Scientists have calculated this Every extra hour of sedentary lifestyle increases the risk of stroke by 14%. But the lead author of the study, Dr. Stephen Hooker, said the find also showed that the risk of stroke can be reduced with exercise.

In the same way it was shown that Doing three and a half hours of light exercise a week reduces the risk of stroke by 26%, compared to less than two hours of exercise a day. Light exercise may include doing housework or walking around the house. even so an even greater protective effect has been registered in people who engage in more intense physical activity.

The people who did 14 or more minutes of moderate or vigorous exercise -like walking a brisk walk, cycling or even working in the garden- risk reduced by 47% compared to people who did less than three minutes a day. For him Hooker, the optimal amount of moderate exercise for people in their 60s is about 25 minutes a day, according to data.

The expert noted this the study had some limitations, above all accelerometers mounted on the thigh did not register any physical activity from the waist up or the position in which people were stuck. Another limitation was that these they only took a seven-day snapshot of a person’s activity levels, this may change during the follow-up period.

Finally, the authors acknowledged this the small sample size of cerebrovascular accidents did not allow them to make a separate analysis of the different types of stroke, ischemic and hemorrhagic. IN Ischemic Stroke, which represents 80% of strokes, occurs when there is a blockage of a blood vessel that prevents blood from reaching a part of the brain. IN hemorrhagic stroke, This happens when a blood vessel ruptures, flooding part of the brain with too much blood and depriving other areas of adequate blood supply.

the stroke is one of the world’s leading causes of death and disability. IN Great Britain there are more than 100,000 strokes a year, causing 38,000 deaths. About 1.3 million people in the United Kingdom have suffered a stroke. IN USA, more than 795,000 people suffer a stroke each year, of which 137,000 die.
