History buffs, especially those into the Georgian and Victorian eras, may have heard of the old practice where doctors recommended “sea air” as therapy for their patients. It sounds dreamy, doesn’t it? Nowadays, extended stays by the ocean may seem pointless, especially considering the effectiveness of modern antibiotics against conditions like tuberculosis. Nevertheless, recent studies shine a light on the idea that staying close to the sea could actually help you live longer, although the science behind it is still a puzzle.
Coastal Living and Lifespan
A number of earlier studies hinted at various health perks from living by the coast. This time, researchers from Ohio State University took a closer look, investigating how living near coastal waters affects lifespan. They analyzed census data from more than 66,000 individuals, checking how long people lived in relation to their proximity to various bodies of water. What they discovered was quite intriguing: folks residing near oceans tended to live longer compared to those near inland lakes and rivers, especially in urban settings. Interestingly, rural inhabitants close to inland waters enjoyed better longevity.
“The analysis indicated that people living along the coast could expect to enjoy a lifespan longer than the national average of 79 years, while urban dwellers close to rivers and lakes predicted living closer to 78 years,” shared environmental health scientist and study co-author Jianyong Wu in a press release. The research team expected water proximity to contribute to health benefits, but were surprised by these significant differences.
Factors Affecting Health in Coastal Areas
According to the study, published in Environmental Research, living close to the coast provides several advantages often lacking in inland regions. Several perks come into play, such as more recreational options, reduced drought risks, better public transport, milder climates, and ultimately, cleaner air. Those residing near the ocean typically earn higher incomes too, as coastal properties usually carry a hefty price tag. Yet these benefits come with urban challenges, such as pollution and poverty, which can undermine health.
“We anticipated that interactions with any ‘blue space’ would grant some forms of health benefits, but were taken aback by how pronounced the differences were between coastal and inland dwellers,” Wu explained. A 2023 research piece further ties coastal accessibility to health improvements, with similar findings observed in Europe and Australia. However, this correlation weakened in lower-income groups, though some benefits were still noted.
Poor Access to Functions in Urban Blue Spaces
Numerous studies – including one conducted in 2021 – have confirmed that being near water enhances wellness. Many are drawn to oceans and lakes for their soothing impact, which helps reduce stress and elevate mood. These environments promote physical activities like swimming or kayaking, alongside social gatherings like picnics and birthdays. All of this contributes to the reduction of various health issues like heart disease and depression.
This latest research from Ohio State is the first in-depth look at how different types of water influence longevity in the U.S. The findings underscore that there might be complex societal and environmental factors affecting health disparities. According to Cao, it signals a potential for further studies on how urban living setbacks like noise, pollution, and poor infrastructures might limit the positive attributes of “blue spaces.”
The overall message points towards the fundamental need for nature in our lives and its healing qualities, though there’s still much to unravel regarding this connection.
