Stroke patients who take regular walks or do light exercise, such as biking in the park, can cut their risk of dying prematurely in half.
A 54% lower risk of death from any cause was seen in people whose exercise levels reached the equivalent of at least three to four hours of walking or gardening per week, or two to three hours of cycling.

The study was published August 11, 2021 online in Neurology, the medical journal of the American Academy of Neurology. The study found the greatest benefit for younger stroke survivors, because when people under age 75 did at least that amount of activity, the risk of death was reduced by 80%.
Study author Raed Gendi, University of Calgary in Canada and member of the American Academy of Neurology, said: “Our results are exciting, as only three to four hours of walking per week were associated with to a significant reduction in mortality, and this may be possible for many community members with stroke. “Additionally, we found that people had a greater benefit from walking six or seven hours per week. These findings may have implications for guidelines for future stroke survivors.”
The study included 895 people with an average age of 72 who had a previous stroke and 97,805 people with an average age of 63 who had not had a stroke.
Average weekly physical activity was assessed by questions on activities such as walking, running, gardening, weight training, cycling and swimming. For example, people were asked, “In the past three months, how often did you walk for exercise? How much time did you spend each time? And the researchers used the frequency and duration of each type of physical activity to calculate the amount of exercise.

The researchers followed the participants for an average of four and a half years. After taking into account other factors that may influence the risk of death, such as age and smoking, the researchers found that 25% of people who had ever had a stroke died from any cause, compared with 6% of people who had never had a stroke. ‘never had a stroke.
In the stroke group, 15% of people who walked at least three to four hours per week died during follow-up, compared with 33% of those who did not do this minimal exercise. In the group of people who had never had a stroke, 4% of people who exercised this amount of activity died, compared to 8% who did not.
Researchers have found the greatest reduction in mortality in people with a history of stroke who are younger than 75 years old. In this group, 11% of those who exercised little died, compared with 29% who did not.
Former stroke patients under age 75 who performed minimal physical activity were almost 80% less likely to die during study follow-up than those who did not. And people over 75 who exercised the bare minimum did not have any fewer benefits, but they were 32% less likely to die.
“Our results suggest that minimal physical activity may reduce long-term mortality from any cause in stroke survivors,” Jundi said. only thirty minutes a day. “
