What are Blue Zones?
What began as a National Geographic expedition, led by Dan Buettner, to uncover the secrets of longevity, evolved into the discovery of five places around the world where people consistently live to be over 100 years old. These regions, known as the Blue Zones, have sparked a global health movement. Dan and his team of demographers, scientists, and anthropologists identified nine common, evidence-based lifestyle characteristics among these long-lived communities, known as the Power 9®.
In 2004, Buettner, CEO of Blue Zones LLC, partnered with National Geographic and the National Institute on Aging. Together, they identified five demographically confirmed, geographically defined areas with the highest percentage of centenarians:
Loma Linda, CA, USA
Nicoya, Costa Rica
Sardinia, Italy
Ikaria, Greece
Okinawa, Japan
These zones were located using epidemiological data, birth certificates, and other rigorous methods. The resulting discoveries laid the foundation for the Power 9® and a blueprint for improving community health in the U.S.
Meet the Five Blue Zones
Here’s a closer look at the five original Blue Zones and what we can learn from each:
Okinawa, Japan
Home to the world’s longest-lived women, Okinawa’s longevity is tied to a plant-forward, anti-inflammatory diet featuring sweet potatoes, tofu, goya (bitter melon), turmeric, and sea vegetables. Residents practice ikigai, a strong sense of life purpose, stay active naturally, and enjoy deeply rooted social connections.
Sardinia, Italy
This Mediterranean Island has one of the highest concentrations of male centenarians. Sardinians live in hilly terrain, walking daily and tending gardens. Their traditional diet includes beans, sourdough bread, goat’s milk, and red wine in moderation. Family loyalty, laughter, and daily interaction with loved ones are cornerstones of their well-being.
Ikaria, Greece
Ikaria has some of the lowest rates of dementia and cardiovascular disease in the world. Residents follow a Mediterranean diet rich in wild greens, olive oil, and legumes. They lead low-stress lives, characterized by regular naps, natural movement, and strong community bonds, which promote both lifespan and brain health.
Nicoya Peninsula, Costa Rica
Nicoyans benefit from the lowest middle-aged mortality rate in the world. Their daily lives include low-intensity physical activity, spiritual practices, and strong intergenerational family ties. Meals feature beans, corn, and tropical fruits. Their concept of plan de vida—life purpose—gives them direction and fulfillment.
Loma Linda, California
This U.S. Blue Zone is home to a large population of Seventh-day Adventists, many of whom live 10 years longer than the average American. Their longevity is rooted in a biblical, plant-based diet, regular rest (including Sabbath observance), faith practices, and the avoidance of alcohol, tobacco, and processed foods.
The Power 9®: Universal Longevity Habits
From these five communities, Buettner’s research team distilled nine common lifestyle traits—known as the Power 9®—that promote vitality and add years to life:
Move Naturally
Exercise isn’t formal or forced. People stay active through activities such as walking, gardening, and performing everyday physical tasks.
Know Your Purpose
Having a reason to wake up in the morning—called ikigai in Japan or plan de vida in Costa Rica—can add up to 7 extra years of life.
Downshift Daily
Stress leads to inflammation and disease. Blue Zone residents manage it through daily rituals, such as prayer, naps, meditation, or evening tea.
Follow the 80% Rule
Okinawans say hara hachi bu—stop eating when you’re 80% full. This helps maintain a healthy weight and metabolism.
Eat a Plant-Based Diet
Legumes, whole grains, fruits, and vegetables form the foundation of a healthy daily diet. Meat is typically eaten sparingly, reserved for special occasions.
Drink Alcohol in Moderation
Except in Loma Linda, most Blue Zone populations drink 1–2 servings of wine or alcohol daily—typically with food and friends.
Belong to a Faith-Based Community
Nearly all Blue Zone centenarians participate in a spiritual or religious group, which supports both mental health and longevity.
Put Family First
Multigenerational households and a deep respect for elders create emotional security and social support systems.
Find the Right Tribe
Social circles shape our habits. In Blue Zones, people surround themselves with friends and family who reinforce healthy behaviors.
But how can you benefit from these insights without relocating?
Bringing Blue Zones to America
Buettner and his team realized that individual responsibility alone couldn’t sustain healthy behavior. They launched the Blue Zones Project, working with policymakers, schools, businesses, and citizens to re-engineer communities based on the Power 9® principles.
What You Can Do Today
Life Radius
People spend approximately 90% of their lives within a 5-mile radius of home. Blue Zones Projects target this “Life Radius” with environmental and policy changes to make healthy choices easier:
Fruit bowls instead of candy dishes
Serving meals from the stove, not the table
Standing desks, safe walking paths, and fewer vending machines
Albert Lea, MN: The First Test
In 2008, Albert Lea became the first U.S. city to adopt Blue Zones principles. Sidewalks were expanded, restaurant menus were modified, schools removed candy incentives, and grocery stores reworked their checkout systems. The results:
3.2-year increase in life expectancy
7,280 pounds of collective weight loss
40% reduction in healthcare costs
Scaling the Success
The success in Albert Lea led to Blue Zones Projects in larger cities, such as Los Angeles, Beach Cities, and Fort Worth, TX, as well as communities in Iowa and Hawaii. These cities experienced measurable declines in smoking rates, BMI, and increases in healthy eating habits.
The Vitality Compass
Blue Zones collaborated with the University of Minnesota to create the Vitality Compass, which helps individuals measure their biological age and life expectancy based on their lifestyle. Users receive personalized recommendations aligned with the Power 9®.
A Final Word on Longevity
“I just forgot to die.” — An Ikarian Centenarian
What began as a global quest to discover longevity hotspots has evolved into a public health movement transforming American cities. By reshaping environments, creating supportive communities, and aligning with the Power 9® principles, Blue Zones is proving that the path to a longer, healthier life is not just possible—it’s scalable.
