Exceptionally excessive longevity is the prime attribute of the so-called Blue Zones across the globe: from Sardinia, Italy, to Okinawa, Japan, analysis on these areas has been on the core of longevity science and mainstream well being dialogues for over 20 years.
Individuals who dwell longer, extra optimum, more healthy lives than the worldwide common mark the excellence in these areas or communities. One such Blue Zone is the Nicoya Peninsula in northern Costa Rica, revered for its distinctive well being outcomes since 2014. However, current research reveal that the scale and impression of this Blue Zone are usually not solely diminishing however are anticipated to fade throughout the subsequent 20 years.
As Luis Rosero-Bixby, a Costa Rican public well being and demography skilled at The Central American Population Center of the University of Costa Rica, stories, a number of underlying elements is perhaps contributing to this gradual shrinking, together with elevated charges of weight problems, stress and sedentary existence adopted by the Peninsula residents in recent times.
Moreover, accelerated urbanization and general globalization may additionally be impacting this tendency. Large-scale developments, augmented vacationer exercise, and cultural shifts have considerably affected the area’s conventional way of life — life habits fostering longevity and well-being have been changed with sedentary behaviors, unhealthful dietary patterns and extra isolation.
Another proposed rationale behind this long-lived discount entails a generational evolution. “If they ask me what can we do to prevent Nicoya from ceasing to be a Blue Zone, I’d say we can’t do anything because these generations, born in the 40s, already tend to decreased longevity,” says Rosero-Bixby. But the query stays.
“It is a million-dollar question we won’t fully answer: Why the Nicoya Peninsula? We have some hints (low-stress levels and diet, for instance), but we have never fully explained every aspect that made it a Blue Zone. In contrast, we don’t entirely know why the reverse effect is now happening either,” notes Rosero-Bixby.

Revealing numbers
Initially 180,000 in 2004, the variety of centenarians has decreased to twenty,000, suggesting this famend Blue Zone not covers a few of its 5 authentic places (Santa Cruz, Hojancha, Carrillo, Nandayure, and a part of Nicoya). Indeed, it’s shrinking with no observable, important shift.
“There is still a stronghold of older adults there who continue to show high longevity, although the trend shows that this Blue Zone will keep getting more undersized, and perhaps in 20 years from now when we redo the map, the circle (of the blue area) will be just a speck or completely vanished altogether,” Rosero-Bixby says.
When it involves timing “it’s hard to say when exactly it might fade, but the fact is that over the years, the size of the Blue Zone has been dwindling. Nevertheless, the decline does not mean the Nicoya Peninsula is no longer a Blue Zone. It is a longevity blue centriole, clearly.”
The Nicoya Peninsula sheds mild on the declining Blue Zone as a vital instance of sustainable dwelling that would inform and encourage a bigger world viewers. Losing these long-lived websites might be detrimental to bettering public well being and well-being throughout the area and past.
An rising Blue Zone
After analyzing database charges of deaths and births and evaluating these with the electoral rolls of the Supreme Electoral Tribunal (TSE), Rosero-Bixby — referred to as the “father of demography in Costa Rica” — discovered what might be a second Blue Zone throughout the nationwide territory.
His analysis detected a brand new sizzling spot the place the loss of life price for these over 60 is far decrease than the nationwide common. Specifically, it’s 0.81 or 19% decrease in three of the numerous cantons of Alajuela (one in all Costa Rica’s central provinces), together with Upala, Los Chiles and Guatuso. Enter — a probably novel Blue Zone.
Rosero-Bixby explains that future traces of inquiry are required to find out whether or not or not these cities qualify as longevity hubs. Still, he believes it’s the first good indication that one thing uncommon is occurring in that space. “With these data points, we have to wait a little longer for more definitive conclusions, but it should be further investigated.”
He provides, “just as Nicoya’s Blue Zone emerged in 2014, studying what is happening in Alajuela would be worthwhile and also necessary to rule out it is not a product of distorted data. Perhaps it is truly the emergence of a new Blue Zone!”

A word on preservation

Maintaining the Nicoya Peninsula as a Blue Zone would require a complete, intercultural strategy addressing social, financial and environmental elements. Educating the native inhabitants concerning the worth and benefits of time-honored life-style, household and dietary dynamics generally is a salient first step.
By reinforcing the integral well being advantages of those distinctive traditions, Nicoya residents might be additional inspired to maintain their millenary social rituals and thrive. Initiatives to stability financial growth and environmental preservation can be advantageous.
For occasion, selling accountable tourism practices that respect and help native tradition can generate income whereas minimizing the destructive impacts on Nicoya’s conventional way of life. Besides, broadening the idea of Blue Zone to embody neighboring areas might assist protect and develop this longevity well being oasis.

The backside line
The shrinking of Costa Rica’s Blue Zone is a reminder of the fragility of those distinctive and priceless cultural legacies and longevity ecosystems.
Through correct schooling, sustainable growth, and extra modern approaches to Blue Zones, collective efforts can safeguard the world’s heritage and contribute to the overarching human pursuit of main more healthy, longer and happier lives.
