Living Near Water May Extend Your Lifespan

Recent research indicates that residing close to bodies of water, especially the ocean, could be associated with increased longevity. A comprehensive study conducted by researchers at The Ohio State University analyzed population data from over 66,000 census tracts across the United States to explore the link between proximity to waterways and life expectancy. The findings reveal a significant correlation: individuals living within approximately 30 miles of an ocean or gulf tend to live longer, often exceeding the national average lifespan by a year or more.

However, the relationship becomes more complex when considering inland water bodies. The study discovered that people living in urban areas near inland lakes or rivers larger than four square miles do not necessarily experience the same longevity benefits. In fact, in these inland urban settings, proximity to water was associated with a slightly shorter lifespan, averaging around 78 years compared to the coastal residents.

The study suggests several factors contribute to these differences. Coastal regions often benefit from milder temperatures, lower maximum temperatures, better air quality, improved transportation options, and increased recreational opportunities. These environmental advantages, along with higher average incomes, may play critical roles in promoting longer life expectancy among coastal populations.

Conversely, inland urban water areas might face challenges such as pollution, higher temperatures, fewer recreational facilities, and environmental risks like flooding, which could offset potential benefits.

The research highlights the importance of environmental and social determinants of health. It is the first systematic examination of various types of "blue space"—natural water environments—and their relationship with longevity in the U.S. The findings raise important questions about how urban planning and environmental policies can enhance health outcomes.

According to lead researcher Jianyong "Jamie" Wu, understanding these disparities can inform future public health strategies. The study underscores that living near coastlines may provide health advantages, but these are intertwined with broader societal and environmental factors. As the U.S. faces challenges like climate change and urbanization, ensuring equitable access to the benefits of water proximity remains a vital concern for public health.
