Effects of Exercise on Brain Health
A new study from China of nearly 17,000 people found that both couch potatoes and extreme fitness enthusiasts showed signs of accelerated brain aging compared to those who exercised in moderation. The research challenges the common belief that more exercise is always better for brain health, suggesting that excessive exercise might harm the brain through different biological pathways. Moderate physical activity was associated with better preservation of white matter and key brain regions involved in memory and thinking.
