Green space proximity and dementia risk study

A long-term study conducted by Stockholm University and the Karolinska Institute, published in the journal ‘Alzheimer’s & Dementia’, indicates that living near green spaces is associated with a significant reduction in dementia risk.

Tracking nearly 3,000 participants over 16 years, researchers utilized satellite data to measure vegetation density. The findings suggest that the protective effect is most significant when green areas are within a 100-meter radius of a residence, showing a roughly 20 to 21 percent reduction in risk. This correlation was observed to be stronger in women than in men.

Lead researcher Cecilia Stenfors noted that the immediate environment is a critical factor for brain health and healthy aging. Potential mechanisms for these benefits include stress reduction, improved sleep, increased physical activity, and enhanced social interaction. The study also suggests that green spaces may offer indirect protection by buffering against environmental stressors such as air pollution, traffic noise, and extreme temperatures.
