Healthy living is often framed as a series of personal choices—what to eat, how much to exercise, or when to go to bed. However, the environment surrounding those choices may matter as well. Research suggests that neighborhood features such as greenery, walkability, and access to everyday services may be associated with measures of cardiovascular, metabolic, and even brain health.
In a study involving more than 24,000 adults, people living in areas with greater amounts of greenery had up to a 14% lower risk of dyslipidemia. Dyslipidemia means having unhealthy levels of fats, such as cholesterol or triglycerides, in the blood. Abnormal levels of these fats can increase cardiovascular risk, making the findings another indication that the places where people live may be associated with factors that influence long-term health.
Other research has found a similar relationship between green space and cardiovascular disease. Living in neighborhoods with greater tree cover and access to parks was associated with nearly a 14% lower risk of cardiovascular disease. Green surroundings may provide more opportunities for physical activity and time outdoors, although studies showing an association cannot prove that greenery itself is responsible for the difference in risk. Personal habits, income, access to healthcare, and other neighborhood characteristics can also influence health.
How easily people can move around their neighborhoods may matter as well. Walkability describes how well an area supports walking through features such as sidewalks, connected streets, pedestrian-friendly design, and nearby destinations. A May 2026 study of middle-aged women found that those living in more walkable neighborhoods had lower levels of certain inflammatory markers and healthier levels of blood fats. These findings suggest that communities that make everyday movement easier may help create conditions that support cardiovascular health.
Neighborhood accessibility may even have connections to brain health later in life. Researchers found that older adults living in areas with less access to essential destinations—including grocery stores, pharmacies, postal services, and bus stops—were more likely to have lower scores on cognitive assessments. In contrast, living in communities with better access to these resources was associated with greater cognitive resilience, or a better ability to maintain thinking and memory abilities despite age-related changes.
Taken together, this research illustrates how health is shaped by more than individual decisions. The environments where people live can make it easier or more difficult to engage in healthy behaviors. Not everyone can choose a neighborhood based on its trees, sidewalks, or nearby services, but people can look for opportunities within their surroundings. Walking to a nearby destination when practical, visiting a local park, spending time outdoors, or finding safe places to be physically active can help make the environment part of a healthier daily routine.
