New research suggests that living near the ocean may be good not only for the soul, but also for longevity. A study led by Ohio State University found that people living within 50 km of the coast tend to live about a year longer than the U.S. national average. Environmental and lifestyle factors—including milder climates, better air quality, and access to recreational activities—are likely contributors.

Physical and recreational benefits

Coastal residents are more likely to engage in outdoor activities, from walking and swimming to paddling and diving. This increased physical activity is associated with lower rates of obesity and cardiovascular disease. Recreational divers, in particular, may benefit from the combination of aerobic exertion, social connection, and mindfulness often associated with underwater exploration.

Inland waters show mixed results

The study also looked at communities near inland lakes and rivers. While rural areas occasionally showed modest gains, urban proximity to inland water bodies was associated with slightly reduced life expectancy—possibly due to air pollution, flooding, or limited access to quality green or blue space.
