Inside one of the World’s Blue Zones

Inside one of the World’s Blue Zones 
<br>Part I: What I learned in Sardinia 

In 2025 I found myself in a little village in Sardinia, Italy, with my wife Wendy. We were stationed about 800 metres above sea level in shepherd country. The terrain was famously hilly and the narrow walkways often had cobblestones underfoot. Each step felt like exercise, and there was nothing leisurely about it.

Around us the elderly and youth moved all day, with varying degrees of difficulty. There were no gyms where we were, daily life provided enough of a challenge. Food wasn’t quick or convenient there but slow and purposeful. Pasta and bread were made from scratch, vegetables were pulled from the earth of backyard gardens or sourced manually at local markets. I helped a family prepare a meal just once – and can attest its arduous nature. Yet the people worked relentlessly to share what they had over wine and stories with relatives, friends and neighbors. Villagers would often keep their doors open for townspeople to drift in and out. The lifestyle was messy, warm and deeply human. It was in these moments I began to grasp an understanding of what a Blue Zone really embodied. More than a diet or a sum of its parts, it was a way of living.

Sardinia is just one of the five known Blue Zones around the world, identified for a unique make up that allows inhabitants to live exceptionally long, healthy lives. Other such regions include Okinawa in Japan, Ikaria in Greece, Nicoya in Costa Rica and Loma Linda in California.Their customs and habits are steeped in history and culture, a result of their environments, and although spread far across the map, the study of these distinct areas has brought to light noticeable parallelisms. 

Okinawa, Japan

The Art of Purpose

In Okinawa, women live longer than almost anywhere else on Earth. They fill their plates with vegetables - in particular sweet potatoes, and tofu. The children are taught to practice 'Hara hachi bu' – to eat until you are 80% full – a habit they carry through to old age. Here the notion of 'Ikigai' is observed, a Japanese concept built upon 'a reason for being', formed at the intersection of passion, vocation, your mission and your profession.

Purpose for Okinawans does not follow career ambition or material success; it is often found in caring for family, tending a garden, immersion in community groups or in the art of giving. Their 'moai' – a lifelong close-knit social support group – ensures no one eats, celebrates, or ages alone.

Nicoya, Costa Rica

A REASON TO RISE

Within the Nicoya Peninsula, in Costa Rica, which boasts the world's lowest rates of middle-age mortality, the locals live by the key cultural belief 'plan de vida', which translates to 'plan of life' or 'reason to live'. They are in a constant state of movement, chopping wood for traditional stoves, walking great lengths and growing their own food. Their activity comes from their daily lives and, as in Sardinia, structured exercise is for many a foreign concept.

The earth is rich and the sun shines brightly here, allowing for a diet built on local whole foods such as corn, beans and squash, staples often referred to as 'the three sisters'. The climate encourages plenty of outdoor activities and a slow-paced lifestyle laden with rest and enjoyment.

WHERE TIME SLOWS

On the island of Ikaria, it's a common jest amongst locals that they 'forget to die'. Here, one in three residents reach their 90s and rates of chronic disease are uncommonly low. Their way of living is leisurely, the pace 'siga-siga' (slowly, slowly) with siestas built-in to the culture. Again the terrain is inherently hilly, and daily activity is unavoidable.

Perhaps their plant-based Mediterranean diet of wild greens, beans, olive oil and herbs plays a part in their longevity, or perhaps it's the clean air and connection to nature. In any case, living life at your own pace clearly has its benefits; with cognitive disorders such as dementia almost non-existent in this region, despite an ever aging population.

Faith and Routine

In Loma Linda, South California, just shy of 100km from the city of Los Angeles, a close-knit community of Seventh-day Adventists are quietly outliving most Americans by almost a decade. We see the familiar values of a strong sense of community, stress reduction through Sabbath observance and the adherence to a plant-based diet. The community avoids alcohol, smoking, and encourages engagement in natural movement as a part of daily life. A well-studied population, the Loma Linda community is frequently cited in public health literature as an example of the association between lifestyle factors and improved preventative health outcomes. Observational research from the Adventist Health

Studies reports lower incidence of cardiovascular disease, type 2 diabetes and some cancers. What can be found in the Blue Zones is perhaps not a secret formula, but a shared framework for living. Movement woven into daily processes, food prepared and consumed intentionally, purpose anchored beyond the self and an advocacy for connection and rest. Longevity, in these settings, appears less about extending life and more about deepening it. It may be that the extra years are not so much the goal, but merely a very, very welcome bonus.
