Study Links Tree Canopy to Better Heart Health

The University of Louisville's Green Heart Louisville Project has revealed that residents living in neighborhoods with increased tree and shrub plantings experienced significantly lower levels of inflammation, a key risk indicator for chronic diseases like heart disease. Conducted by the Christina Lee Brown Envirome Institute, the study involved the planting of over 8,000 trees and health monitoring of 745 participants, finding a 13% reduction in high-sensitivity C-reactive protein among those in greened areas. The findings suggest that enhanced greenery can lower heart attack risks by approximately 10-15%. The initiative highlights the potential health benefits of urban greening and advocates for increasing green spaces in communities. UofL officials emphasize the broader implications for public health and economic savings, estimating that Louisville's tree canopy contributes $330 million annually in environmental benefits. This research may pave the way for similar projects in other urban areas.
