Living by the ocean may help you live longer
A new study has found that coastal residents live a year or more longer than those who live inland.

Researchers from Ohio State University have found that people who live by the ocean tend to live longer than those who don’t, especially when compared to those living in urban areas near rivers or lakes.
While many South Africans already seek out coastal properties for lifestyle or leisure, the findings offer scientific backing to the idea that living near the sea could be as beneficial for your health as a balanced diet or regular exercise.
Published in the journal “Health & Place”, the study analysed data from more than 66,000 people, looking specifically at the connection between proximity to bodies of water - referred to as “blue spaces” - and life expectancy.
The results showed that people living by the coast were expected to live a year or more longer than the average life expectancy of 79.
In contrast, those in urban areas near inland waters had a lower average life expectancy, around 78 years.
Dr Jianyong Wu, an environmental health scientist involved in the research, explained that, “Overall, the coastal residents were expected to live a year or more longer than the 79-year average, and those who lived in more urban areas near inland rivers and lakes were likely to die by about 78 or so.”
The researchers were initially surprised by the sharp contrast between coastal living and urban inland living, given previous studies have shown general health benefits associated with all types of blue spaces.
What’s behind the longevity?
The study doesn’t prove direct causation, but it does suggest a strong link between coastal environments and better health outcomes.
According to the team, coastal areas typically enjoy cleaner air, more moderate temperatures, and greater access to recreational spaces.
These factors can encourage physical activity, reduce stress, and improve overall mental and physical health.
Socioeconomic status may also play a role
Coastal properties often come with a higher price tag, and higher income levels are associated with better healthcare, healthier diets, and less exposure to environmental pollutants.
Interestingly, the study found that rural areas near inland water sources, such as lakes or rivers, did show a slight increase in life expectancy, but not to the same extent as coastal areas.
Meanwhile, urban inland areas seemed to cancel out the potential health benefits of nearby blue spaces, likely due to issues such as pollution, noise, lack of green space, and socioeconomic inequalities.
