A small study found that residents of neighborhoods with larger green spaces may be less stressed and more likely to have a heart attack or stroke than those in many green spaces.
Researchers at the American Heart Association have noted that in the general population, long-term green areas are connected to residential areas, that the risk of death from heart disease and respiratory problems has decreased and that the risk of hospitalization for heart attacks and strokes had decreased. But there is little evidence to show if this link is true at the individual level.
For this study, researchers tested a range of vital signs of heart disease stress and risk in blood and urine samples in 408 patients in a heart disease hospital in Louisville, Kentucky. . The researchers also used satellite data from NASA and the US Geological Survey to estimate the size of the green spaces where each person lives.
The study found that adrenaline levels in urine samples were lower than those living in green areas, compared to people living in areas with fewer green areas, which indicates that stress levels were lower. They also have an indicator of oxidative stress. In addition, people living in more green spaces have been able to maintain healthy blood vessels, compared to those living in limited green spaces.
"The magnitude and power of the more environmentally friendly health effects are surprising," said Arunny Battnagar, lead author of the study. If the results of this study are confirmed, continued interaction with nature could be a way to reduce the risk of heart disease. "
