A study examining data from over 66,000 U.S. census tracts revealed that coastal residents live, on average, at least one year longer than the national average. However, this longevity benefit does not extend to those living near inland bodies of water in urban areas.
Residing near oceans or gulfs is correlated with a longer lifespan, possibly due to cleaner air, milder weather, and more opportunities for physical activity. In contrast, urban dwellers near inland water areas tend to have shorter life expectancies, likely due to pollution and unfavorable environmental and socioeconomic factors.
Researchers conducted a comprehensive study by analyzing U.S. population data, focusing on life expectancy in relation to proximity to water sources. They compared life expectancy data from 2010–2015 with the distance to coastal and inland water bodies, while controlling for numerous factors that affect longevity.
A key distinction was found in that coastal areas have fewer hot days and lower maximum temperatures than inland water regions. It was also discovered that people living along coastlines breathe purer air, with decreased exposure to air pollutants and smoke from wildfires. Prior studies have linked proximity to water with improved health outcomes, such as increased physical activity, reduced obesity rates, and better cardiovascular health.
Coastal landscapes may offer logistical and health benefits, characterized by flatter terrain and improved transportation access. In contrast, inland water areas often have rugged, mountainous terrain, making navigation more challenging and impacting factors like emergency response times and daily stress levels.
These findings have significant implications for the millions of Americans residing near inland waters. Communities in these areas may need to tackle environmental issues that could be jeopardizing residents' health and lifespan.

Unveiling complexity in blue spaces and life expectancy
As we grow older, our brains undergo various changes that lead to cognitive decline. The acetylcholine-dependent neurotransmitter system slows with age, primarily causing older adults to struggle with concentration and working memory. It also contributes significantly to neurodegenerative diseases like Alzheimer's.
Sugar sweetened drinks have faced criticism for years, with diet versions often viewed as safer. A new study ties both sugar-filled and artificially sweetened drinks to elevated chances of metabolic dysfunction-associated steatotic liver disease (MASLD), the severe liver disorder previously named nonalcoholic fatty liver disease. This occurs when fat accumulates in the livers of individuals who rarely or never drink alcohol.
Regular exercise keeps your body and brain sharp as you age. It preserves mobility, supports independence, and may slow cognitive decline. New research shows exercise reprograms the body at the molecular level, fundamentally transforming biological systems from the inside out.
