New research suggests that even five minutes of light exercise daily could help reduce dementia risk, offering hope to those who struggle with physical activity. A study led by Johns Hopkins Bloomberg School of Public Health found that engaging in at least 35 minutes of moderate to vigorous physical activity per week lowered dementia risk by 41% over four years.
The research analyzed nearly 90,000 adults in the UK, tracking their activity through wearable devices. Findings showed a clear correlation: those who exercised between 35 and 69.9 minutes per week had a 60% lower dementia risk, while those who exceeded 140 minutes saw a 69% reduction. Even frail individuals benefited from low-dose exercise, reinforcing the idea that any movement is better than none.
Experts believe exercise promotes brain health by increasing blood flow, reducing inflammation, and aiding in the removal of metabolic waste. While this study does not confirm causation, it aligns with broader research showing that an active lifestyle can help delay cognitive decline.
