That sea air is good for health is now almost a cliché, a certainty that is also supported by science.
Generations of children have been sent by pediatricians and concerned parents to play on the beach just to "absorb iodine," perceived as a kind of cure for every illness, whether actual or potential.
Now, however, researchers at Ohio University in the US have confirmed that living a few steps from a beach can extend your life, guaranteeing "two extra years" of life for anyone who can look out their window and gaze at a blue expanse. And no, it's not just iodine.
Did the architect already know this? – Le Corbusier understood it before anyone else. Now elderly, after a life filled with commitments and pleasures, the famous architect designed and built a minimalist wooden hut near Roquebrune-Cap-Martin, on the French Riviera, in 1951.
There he retreated, just a few steps from the sea among acanthus, agave and eucalyptus trees, until 1965, when he died during one of his many swims in the water in front of his “Cabanon”.
Perhaps his long life was extended precisely by that choice to leave everything behind to move closer to the Mediterranean, indirectly demonstrating what an American study coordinated by environmental health expert Jianyong Wu of Ohio State University now confirms.
It only applies to the sea – “In general, residents of coastal areas can expect to live one or two years longer than the standard American life expectancy of 79 years,” Wu explained, noting that the beneficial effects of the sea are not replicated equally if one chooses to live near lakes or rivers.
In the second case, in fact, "those living in urban areas near inland rivers and lakes have a life expectancy of about 78 years."
This fact surprised the researchers themselves, but they wouldn't dream of questioning the results of a study based on extensive data analysis. This is the basis of this hypothesis, thanks to a study published in the journal Environmental Research.
A study involving thousands of people – American researchers reached their conclusions after collecting and analyzing data from 66,000 people, linking each person's place of residence and age at the time of death, with the aim of deciphering factors that may influence the latter.
Among the reasons suggested by researchers to explain the phenomenon of marine longevity, there are some that are quite easy to guess.
First of all, the fact that at the coast, the body (and mind) do not have to adapt to the shock of going from excessive heat to cold.
Therefore, a mild climate is perfect for getting outside, spending more time outdoors and inevitably filling your lungs with that famous "good air", which is anything but a myth.
Healthy, Happy, and the Sea – It is true that the sea has a beneficial effect on anyone suffering from allergies or respiratory problems, as well as being a medicine for the skin, hair (strengthened by seawater, which naturally fights dandruff and oily hair) and thyroid.
“Proximity to water, particularly the sea, is associated with many positive measures of physical and mental well-being, from higher levels of vitamin D to better social relationships. Many of the same processes are triggered by green spaces, with some additional benefits,” explained Dr. Matthew White, professor at the University of Exeter and psychologist at BlueHealth, a research program studying the benefits of living near the sea, in an article in The Guardian.
In the same article, White cites another 2013 study that found coastal environments to be the happiest places, with responses roughly six points higher than those collected in urban settings.
On the other hand, going to the beach increases vitamin D levels, while also stimulating the production of endorphins, responsible for improving mood and can prevent autoimmune diseases.
Seawater itself remains a source of magnesium, iodine, and potassium, minerals that fight infections and help the body detoxify and heal.
Finally, it should be remembered that even simply looking at this blue space has a calming effect on the human brain, which is soothed by such a spectrum of colors.
Perhaps for these reasons, throughout history, the sea has often represented a border capable of calming humanity, perceived almost as a protective barrier that should only be challenged in times of emergency.
