New research shows the presence of trees where people live may significantly impact human heart health.
The results find that those living in greener neighborhoods have lower risks of heart attacks, strokes, and other cardiovascular diseases.
Peter James is a lead researcher of the study at the University of California – Davis.
Using over 350 million Google Street View images analyzed with deep learning, James’s team identified street-level vegetation and linked it to long-term health data.
However, areas with more grass were linked to higher cardiovascular risk.
James says trees help by cooling neighborhoods, filtering air, reducing noise, and promoting activity and social interaction. “We’ve evolved as human beings to be in nature….this is our natural setting, not staring at a computer screen….that’s where we thrive… out in trees and nature,” James says.
