A new study has revealed a compelling link between coastal living and increased longevity in the United States, suggesting that people residing within about 30 miles of an ocean or gulf may enjoy life expectancies up to one year longer than those living farther inland.
Researchers from Ohio State University analyzed data from over 66,000 census tracts across the country and found that proximity to the ocean consistently corresponded with higher-than-average life expectancy—even after adjusting for age, race, and income. Coastal residents were expected to surpass the national average life expectancy of 78.4 years by a full year or more, while people in urban areas near large rivers or lakes sometimes faced slightly shorter lifespans.
The study attributes the longevity boost of coastal living to several interrelated factors, including:
-
Milder temperatures: Coastal areas experience fewer days with extreme heat, which reduces the risk of dangerous heat-related illnesses.
-
Cleaner air: Ocean breezes dilute air pollutants, leading to fewer asthma attacks and strokes.
-
Increased recreation: Ready access to beaches and waterfronts encourages physical activity, reducing obesity and improving overall health.
-
Higher incomes and better infrastructure: Coastal counties often have better economic opportunities and faster emergency response times compared to some inland areas.
-
Better mental health: Routine contact with ocean vistas—part of what researchers call “blue space”—has been linked to lower stress and healthier heart rates.
However, the benefits were not the same for everyone living near bodies of water. Urban neighborhoods located near large inland rivers and lakes showed an association with shorter lifespans. Pollution, overcrowding, limited recreational access, and flood risks may partly explain the differences. Interestingly, rural areas near lakes did see some increase in lifespan, likely due to cleaner environments and fewer pollutants.
Researchers stressed that not all “blue spaces” are created equal, and the quality, safety, and accessibility of local water sources are crucial. The study also recommended actions such as cleaning up urban waterways and expanding public access to healthy coastal environments to help spread these longevity benefits more broadly.
“We found a clear difference—in coastal areas, people are living longer,” said lead researcher Jianyong “Jamie” Wu. “It’s likely that various social determinants of health, including complex environmental factors, contribute to health inequities and are playing a key role in these differences”.

The findings summarize statistical links between ocean proximity and longevity, but do not prove that moving to the coast will add extra years to every individual’s life. Personal health depends on many factors, including genetics, lifestyle, income, and access to care. The study highlights trends at a population level—increasing access to clean, safe, and enjoyable environments could improve overall public health, but individual outcomes may vary.
