Living in a tree-filled neighborhood may be as beneficial to the heart as regular exercise, according to new research from the University of Louisville. The Green Heart Louisville Project’s HEAL Study followed hundreds of people living in six neighborhoods in South Louisville before and after the team planted thousands of mature trees near their homes. Results showed that those living in neighborhoods with more trees had lower levels of a blood marker associated with heart disease, diabetes, and cancer compared to those in tree-bare neighborhoods.
The study, which included a control group and intervention, recruited about 750 residents aged 25 to 75 with average household incomes of $50,000. Trees were planted in parts of the study area, leaving others untouched, and participants in the intervention areas showed a 13% drop in levels of a blood marker associated with heart disease.
Trees provide shade, cool areas, and buffer noise, which can contribute to lower rates of cardiovascular disease. They also help filter air pollution, an important factor in urban areas like the study location, which is cut by a major highway. The project plans to plant trees in control group neighborhoods in the future and explore other potential health benefits of tree cover.
The study highlights the importance of equitable access to green spaces in cities and the essential role that nature plays in human health and well-being. The research suggests that green spaces are not just amenities for the wealthy but are essential for all individuals.
