Lessons From the World’s Blue Zones

There are certain regions around the world called “blue zones,” where people routinely live active, vibrant lives well into their 90s — or even past 100. The term comes from longevity researcher Dan Buettner, who worked with National Geographic and leading demographers to find communities around the globe where people live measurably longer, healthier lives. What he found wasn’t one single secret. It was a cluster of simple, interconnected lifestyle habits that anyone can start adopting, regardless of where they live.

The world’s five original blue zones include:

• Okinawa, Japan
• Sardinia, Italy
• Nicoya Peninsula, Costa Rica
• Ikaria, Greece
• Loma Linda, California

These blue zone communities have a much higher proportion of centenarians (people who live to age 100) than surrounding regions, and they share a set of common lifestyle habits that support longevity.

What Makes a Blue Zone?

Buettner’s work was informed by a 1996 study of Danish twins, which found that only about 20% of how long the average person lives is dictated by genes, while roughly 80% is influenced by lifestyle and environment. This is an encouraging finding, because it suggests our day-to-day choices — what we eat, how we move, how we manage stress and who we spend time with — have far more impact on our longevity than most people realize.

Blue zone residents don’t tend to think of themselves as following a special program. They’re not tracking macros or training for ultramarathons. Instead, blue zoners have built their daily lives around environments and social structures that make healthy behavior the default rather than the exception. They move more, eat more plants, experience less chronic stress and stay closely connected to family, friends and faith communities.

Power 9 Habits

Across all five blue zones, Buettner and his team identified nine common lifestyle habits — the “Power 9” — that together support longer lifeand better health. These habits show up in everyday routines, not just in occasional activities.

1.     Move naturally

Blue zone centenarians don’t typically belong to gyms or train for marathons. Instead, they weave physical activity into daily life: walking to visit neighbors, gardening, climbing hills, caring for animals and doing household chores. This kind of regular, low-intensity physical activity is one of the common lifestyle habits that’s been linked to better cardiovascular health and a lower rate of chronic disease.

2.     Know your purpose

Having a strong sense of life purpose is a major theme across blue zones. In Okinawa, this is known as ikigai (“reason for being”), while in the Nicoya Peninsula it’s called plan de vida (“life plan”). Research suggests knowing your purpose is associated with up to seven extra years of life expectancy, giving structure and meaning to daily life, especially in retirement.

3.     Downshift to reduce stress

Chronic stress and resulting inflammation are linked to many age‑related diseases, including heart disease, diabetes and certain cancers. Blue zone inhabitants build daily rituals that help them downshift, such as afternoon naps, prayer, meditation, quiet time to remember ancestors, and regular social interaction. One study highlighted in blue zones research found that a midday siesta lowered stress levels and reduced the risk of cardiovascular disease mortality.

4.     Practice mindful eating

Eating patterns inblue zones emphasize mindfulness and moderation. A well-known guideline is to stop eating when you feel about 80% full, sometimes called the “hara hachi bu” rule in Okinawa. Residents tend to eat their smallest meal in the evening, avoid mindless snacking and let enough time pass between meals for digestion. These simple habits support a healthy weight, better metabolic health and fewer digestive issues over time.

5.     Follow a plant-forward blue zone diet

Blue zone diets center on beans, vegetables, whole grains and nuts, with meat eaten in small portions only a few times a month. In Nicoya, for example, the traditional diet of beans, corn tortillas and vegetables appears to play a role in the region’s high share of centenarians. In Loma Linda, the only North American blue zone, many residents are Seventh-day Adventists who follow a vegetarian or plant‑based “Garden of Eden”-style diet. Studies of Adventists have found that vegetarian Adventists live, on average, several years longer than their non‑vegetarian peers, underscoring the impact of diet on long‑term health.

6.     Wine at 5 — With Friends

In most blue zones (with the exception of Loma Linda), people enjoy moderate alcohol consumption — typically one to two small glasses of red wine per day — with food and in the company of friends. The emphasis is on moderation and social connection, not heavy drinking. Interestingly, in Loma Linda, Adventists largely abstain from alcohol yet still experience exceptional longevity, suggesting that the social connection and other healthy behaviors may be more central than the wine itself.

7.     Find belonging in a faith or values-based community

Nearly all blue zone centenarians belong to a faith-based or strong-values-based community. Attending services or gatherings regularly has been associated with significant longevity benefits, with some analyses suggesting an additional four to 14 years of life for those who participate frequently. In Loma Linda, the weekly Sabbath rest practiced by Seventh-day Adventists — a 24‑hour break from work and commercial activity — reinforces sleep, stress relief and social connection.

8.     Prioritize loved ones first

Blue zone residents tend to prioritize family. It’s common for aging parents and grandparents to live close by or in the same home rather than in separate facilities. People commit to their life partners and invest substantial time and energy in children and grandchildren, creating a strong sense of mutual support. Research connected to blue zones suggests that living in close-knit family structures can add years of life expectancy and improve emotional well-being.

9.     Find your right tribe

Finally,blue zone inhabitants surround themselves with others who reinforce healthy behavior. Their closest friends and social circles share similar values about food, movement, rest and community. This sort of social interaction makes healthy living feel normal and enjoyable rather than like an individual struggle. In public health terms, blue zone communities effectively make the healthy choice the easy choice.

The Blue Zones Project: Blue Zone Communities Close to Home

While the original blue zones are scattered across the globe, the ideas behind them have been brought to several North American communities through the Blue Zones Project, a public health initiative led by Blue Zones LLC. The project focuses on reshaping environments — from city planning to food options — so that residents can more easily practice healthy behaviors.

Two notable examples are Albert Lea, Minnesota, and Fort Worth, Texas.

Albert Lea, Minnesota, became the United States’ first certified blue zone community after piloting the Blue Zones Project. Over time, residents added an estimated 2.9 years to their average life expectancy, smoking rates dropped and the community reported millions of dollars in healthcare savings.

Fort Worth, Texas, saw increases in physical activity, reductions in smoking and improvements in overall well‑being scores after adopting blue zone-inspired changes across workplaces, restaurants and neighborhoods.

These blue zone communities show that the Power 9 habits aren’t just relevant to distant islands or coastal towns. With intentional design and community engagement, everyday environments — even large cities — can make healthy living more automatic, supporting better outcomes for residents and public health overall.

The Financial Implications of a Longer, Healthier Life

Lifestyle insights from blue zones show us that simple, everyday changes can have a big impact on both the quantity and quality of life. But living longer also means planning longer, and that has important financial implications.

Quality of life

Healthier habits can lead to lower lifetime healthcare spending, reduced dependence on caregivers, greater independence, and more time to travel, pursue passions and enjoy social connection with loved ones. For many people, this is the vision of retirement they’re working toward. Aligning your financial resources with healthy living goals can increase the likelihood that you’ll spend more of your retirement years active and engaged rather than managing frequent medical crises.

Longevity risk

Longevity risk is the possibility that you’ll outlive your wealth. The very success of living longer creates new planning challenges: your retirement assets may need to last several decades beyond age 65. That’s whyit’s important to continue growing your assets within a diversified investment portfolio to establish a sustainable withdrawal strategy and consider tax-efficient ways to generate retirement income. These decisions help ensure that a longer life remains a blessing, not a source of financial strain.

Healthcare costs

Healthcare costs are one of the largest expenses in retirement. Recent estimates suggest that a 65‑year‑old individual may need around $172,500 in after‑tax savings to cover healthcare costs over their lifetime, while a couple retiring at age 65 could expect average healthcare expenses of about $330,000. Long‑term care and chronic disease can push these numbers higher, with some analyses indicating that total healthcare spending across two long lifetimes can reach $600,000 or more for a couple.

Blue zone habits — such as regular physical activity, a plant‑based diet, strong social connection and effective stress management — may help reduce the risk of certain chronic conditions and lower overall medical spending, although outcomes will always depend on individual health circumstances. Even if healthy living doesn’t eliminate healthcare costs, it can shift the focus toward preventive care and more active years.

Estate and legacy planning

A longer life also gives you more time for your needs and goals to evolve. Estate planning documents, beneficiary designations, multigenerational legacy plans, lifetime gifting strategies and charitable giving objectives should all be revisited periodically. As your family structure changes, or as you redefine what you want your wealth to accomplish, updating these pieces ensures your plan stays aligned with your values and the realities of a longer retirement.

Creating Your Own Blue Zone

While some retirees are drawn to the lifestyle, slower pace and strong social fabric of blue zone regions, you don’t have to relocate to Okinawa or Sardinia to benefit from blue zone-style living. One of the most encouraging aspects of the Power 9 is how inexpensive and accessible these habits are. Most focus on small changes in daily life, not expensive medical interventions.

A good way to begin is by choosing one or two habits that feel natural:

• Schedule regular walks with a friend or neighbor to combine physical activity with social interaction.
• Add more vegetables and beans to your dinner plate, nudging your diet in a more plant-forward direction.
• Block time for relaxation — whether it’s a short nap, spiritual practice, meditation or quiet reading.
• Explore opportunities for volunteering or mentorship to deepen your sense of purpose and connection.
• Prioritize a consistent sleep routine to support overall health and stress management.

Over time, these small changes can compound, much like the way steady saving and investing compounds in a well‑constructed portfolio. The goal isn’t perfection. It’s building a lifestyle that gently nudges you toward healthier choices day after day.

Aligning Your Financial Plan With a Longer Life

As you think about the future, it’s helpful to remember that true wealth planning is a holistic process. The same decisions that shape your health — your lifestyle, your environment, your relationships — also influence your financial needs and priorities in retirement. When you factor longevity and healthy living into your plan, you’re not just planning to live longer. You’re planning to live better.

Your wealth manager can help you think through questions such as:

• How would living into my 90s or beyond change my retirement income strategy?
• What role should healthcare and long‑term care planning play in my overall plan?
• How can I structure my portfolio today so that I’m prepared for both routine and unexpected medical expenses later on?
• How often should I revisit my estate and legacy plans as my life evolves?
