Exercise Boosts Brain Health After 45
29 Nov, 2025
Summary
- Midlife and late-life exercise linked to lower dementia risk.
- Physical activity may significantly protect against cognitive decline.
- Starting exercise later in life can still offer substantial brain benefits.
Scientists have discovered that consistent physical activity during midlife and later adulthood can substantially reduce the risk of dementia. Research indicates that individuals with the highest levels of physical activity between ages 45 and 64 saw a 41% lower risk, while those aged 65 to 88 experienced a 45% reduction.
This finding is particularly encouraging as it suggests that it is not too late to benefit from exercise for brain health, even if one has not been active earlier in life. Experts emphasize that incorporating regular movement can positively impact vascular health and brain function, potentially slowing cognitive decline.
While the study highlights the importance of these critical windows, general recommendations from health organizations suggest a minimum of 150-300 minutes of moderate aerobic activity per week. Simple habits like regular walks or movement breaks can contribute to better brain health and overall well-being.
