Do you want to reduce the risk of stroke? Scientists have uncovered a simple mystery

Researchers have found that simpler activities, such as housework, can significantly reduce the risk of stroke.

According to a study by San Diego State University (SDSU), vacuuming, wiping, walking pets or fishing can be enough to prevent a stroke.

Stroke can be very serious. According to the CDC, one in six people who died of cardiovascular disease in 2020 was due to a stroke. In addition, in the United States, one person has a stroke every 40 seconds, and one dies from a stroke every 3.5 minutes. In all, approximately 795,000 people in the United States suffer a stroke.

What can someone do to reduce the risk of stroke? Fortunately, the new study has a simple answer.

Imagine watching “Batman” four times a day, two times in a row, or driving 390 miles in each direction on a daily basis. The awkward choice takes about 12 hours – or the same amount of time as most Americans want to sit all day.

The dangerous consequences of prolonged human inactivity are well known. Excessive sitting increases the risk of cardiovascular disease, type 2 diabetes and other chronic diseases, including depression. To counteract the negative effects of a sedentary lifestyle, doctors recommend that adults do at least 150 minutes of moderate to intense aerobic exercise a week.

However, a new study published in the Journal of the American Medical Association by San Diego State University, JAMA Network Openfound that doing lighter daily activities such as housework can significantly reduce the risk of stroke.

“Light-intensive physical exercise may include vacuuming, floor sweeping, car washing, slow walking, stretching or playing,” said Stephen Hooker, dean of SDSU College of Health and Community Services and lead researcher in cohort research.

“We have found that both physical activity and physical inactivity have an independent effect on the risk of stroke. Our research shows that stroke prevention strategies need to focus on both. ”

Hooker and his colleagues measured participants ‘sedentary sitting time and duration and intensity of physical activity in 7,600 adults aged 45 and older, and then compared data with participants’ stroke cases over a seven-year period.

They found that those who did not exercise for 13 hours or more a day had a 44% increased risk of stroke.

Hooker, a former California Active Aging Project coordinator, said the findings were stronger because activity and settlement behavior were measured with an accelerometer, which provided more accurate information than previous studies. A study of healthy lifestyles in older people.

The participants wore a pelvic accelerometer, a sensory motion detector that accurately recorded physical activity and the duration of sitting and standing.

While smartphones and smartwatches try to motivate Americans to exercise more, a surprising percentage of adults do not exercise enough. According to the CDC, only 23% of U.S. adults respond to weekly aerobic and muscle-strengthening recommendations.

However, if it seems impossible to take 10,000 steps a day or close the exercise ring on your watch, Hooker says, getting up several times a day and doing ten minutes of light exercise is an effective strategy to reduce stress. The likelihood of a stroke.

“For overall heart and brain health, exercise as much as you can and sit less,” Hooker said.
