A landmark study using artificial intelligence to analyze Google Street View images found that neighborhoods with more visible trees are linked to a lower risk of cardiovascular disease, while areas dominated by grass are associated with a higher risk.
The research followed nearly 90,000 female nurses for 18 years. It innovatively used AI on street-level images to assess daily environmental exposure, moving beyond simple satellite “greenness” measures.
Researchers suggest trees provide multifaceted benefits grass lacks, including cooling shade, air pollution filtration, noise reduction and encouragement of walkability. Grass-dominated areas often correlate with car-dependent sprawl and pollutant-generating maintenance.
The protective association with trees was strongest within a 500-meter radius of a home, emphasizing that community-wide tree canopy is more impactful than just an individual yard.
The findings argue for prioritizing tree canopy and connected, shaded neighborhoods in urban design, especially for climate resilience and public health, indicating that the type of greenery is a critical factor.
In a revelation that could reshape urban planning and public health initiatives, a landmark study has found that the type of green space outside your door matters profoundly for your heart. Groundbreaking research leveraging artificial intelligence (AI) and decades of health data indicates that living in a neighborhood with abundant trees is associated with a lower risk of cardiovascular disease, while areas dominated by grass show a surprising link to higher risk.
