A new study reveals that even short bursts of moderate-intensity exercise can significantly lower the risk of developing dementia. Researchers found a strong correlation between physical activity and reduced dementia risk, highlighting the importance of incorporating exercise into our routines for brain health.
A new study has revealed a powerful link between physical activity and a reduced risk of dementia. Researchers from Johns Hopkins University in the US found that engaging in as little as 35 minutes of moderate-to-vigorous exercise per week can significantly lower the risk of developing dementia. This equates to a 41 percent reduction in risk compared to individuals who were completely inactive.
The study, published in the Journal of the American Medical Directors Association, emphasizes that even short bursts of exercise, such as five minutes a day, can offer substantial benefits for brain health.The researchers analyzed data from 89,667 adults, with an average age of 63, over a period of 4.4 years. Participants wore activity trackers to monitor their movement levels. By tracking which individuals developed dementia, the researchers were able to establish a clear correlation between physical activity and dementia risk. The findings showed that those who engaged in 36–70 minutes of physical activity per week had a 60 percent lower risk of dementia, while those who exercised for 71–140 minutes per week saw a 63 percent reduction. Individuals who accumulated 140 minutes or more of physical activity per week experienced a remarkable 69 percent decrease in dementia risk. While the study doesn't definitively prove a direct cause-and-effect relationship, it strongly suggests a close link between exercise and brain health. The researchers are eager to stress that individuals at any stage of life can reap the benefits of incorporating more physical activity into their routines. Even those considered frail or nearly frail can potentially reduce their dementia risk through low-intensity exercise. This emphasizes that it's never too late to start exercising and prioritize your brain health
