Living near coastlines could potentially contribute to increased lifespan, according to a recent study.
In a groundbreaking study, researchers from The Ohio State University have identified a connection between living near coastal waters and longer lifespans. Their findings invite planners and policymakers to consider the role of "blue spaces" in creating healthier communities.
The study, which compared urban and rural residents living near large lakes, rivers, and coastal waters, found that urban residents near coastal waters have an average lifespan of approximately 79 years, which is one year longer than the average. In contrast, urban residents near inland water show a slight lifespan benefit, and rural residents near inland water bodies experience no significant difference.
While the study results do not prove causation, they do suggest a correlation between living near coastal waters and longer lifespans. The researchers found a significant and clear difference between those who live near coastal waters and those who live near inland waters.
So, what factors contribute to this difference? The researchers identified several key factors. Coastal areas tend to have milder and more moderate temperatures, with fewer hot days above 35°C and lower maximum temperatures, reducing heat stress. Additionally, coastal areas generally have better air quality, characterized by lower levels of PM2.5 pollution.
Another factor is the environment near coastal waters, which supports more opportunities for physical activity and recreation, benefiting cardiovascular health and reducing stress. In contrast, inland water bodies—especially in urban areas—may be linked to higher pollution, poverty, limited safe recreational opportunities, and flood risks, which can negatively affect life expectancy.
It's important to note that the researchers also acknowledged limitations in their study, such as not tracking the quality or usage of the water itself. However, the evidence they have gathered provides a compelling case for the benefits of living near coastal waters.
In conclusion, the study suggests that living within about 50 km of the coast is associated with about a year longer life expectancy than living near inland waters. As we strive to create healthier communities, policymakers and planners should consider the role of blue spaces in promoting longer, healthier lives.

- The researchers, in their study published in Environmental Health Perspectives, found that environmental science factors such as milder temperatures, better air quality, and opportunities for physical activity and recreation near coastal waters could be contributing to the link between living near coastal waters and longer lifespans in health-and-wellness.
- As policymakers and planners look to create healthier communities, they may want to consider integrating elements of environmental-science, like blue spaces, to provide benefits aimed at promoting longer, healthier lives, as suggested by the study from The Ohio State University, which was first reported in a press release.
