4. Lack of Physical Activity – The Silent Contributor
As we transition to the fourth risk factor, we find that an inactive lifestyle or lack of physical activity can also contribute to the risk of dementia. Regular physical activity not only helps maintain a healthy body but also contributes to preserving cognitive health.
Numerous studies have suggested that regular physical activity, especially during midlife, can lower the risk of various forms of dementia, including Alzheimer’s disease. Exercise improves cardiovascular health, enhances mood and sleep, reduces stress and anxiety, and boosts overall brain health.
Exercise fosters the brain’s plasticity by stimulating the growth of new connections between cells in a wide array of important cortical areas of the brain. Moreover, regular physical activity also helps control other dementia risk factors such as hypertension, diabetes, and high cholesterol. (4)
