We’ve all heard of the seven wonders of the world, but what about the five Blue Zones of the world? These are the rare regions around the globe where people consistently live the longest, healthiest lives. These communities reveal secrets of diet, lifestyle, purpose, and connection that many other areas aspire to. From plant-based diets to close-knit social circles and mindful meals and movement, Blue Zones offer a blueprint for nourishing the mind, body, soul, and spirit.
The Fantastic Five
Blue Zones are “communities where people not only lived longer but also enjoyed a high quality of life in their old age” (Rowan & Rowan, 2024). Where are these mysterious Blue Zones, you ask? The five zones include...
Okinawa, Japan
Sardinia, Italy
Nicoya, Costa Rica
Ikaria, Greece
Loma Linda, California
Each of these zones shares common trends and habits as well as holds some unique ones of its own. Okinawa, Japan, is home to some of the oldest women in the world, known for eating soy-based foods and practicing tai chi. Sardinia, Italy, is home to some of the oldest men in the world, who live in mountain regions, work on farms, and enjoy lots of red wine—in moderation, of course. The Nicoya region of Costa Rica emphasizes a Nicoyan diet rooted in beans and corn, natural physical activity through daily work, and a strong sense of life purpose (“plan de vida”). Ikaria, Greece, thrives on a Mediterranean diet, daily movement through farming, and a lifestyle deeply connected to the land. Lastly, Loma Linda, California, is characterized by a vegetarian diet, Seventh-day Adventist faith practices, and a strong sense of community. While each of these areas holds its own traditions, they all share powerful practices that help people live not only longer but also better.
Blue Zone Habits
So what is so special about these Blue Zones that makes people in these areas live to 100 years old (and older)? The secret lies in their daily habits, specifically nine practices known as the “Power 9.” The Power-9 habits entail:
Move Naturally
Life Purpose
Downshift (reduce stress)
80% Rule (when eating)
Plant Slant (plant-based diet)
Wine at 5 (socialization > alcohol itself)
Right Tribe
Loved Ones First
Belong (community)
The first habit, moving naturally, focuses on daily movement intertwined into their daily lives—through work, habits, and lifestyle. Many people who live in Blue Zones farm or garden, perform yard work, hold labor-intensive jobs, and walk frequently. Incorporating these tasks into their routines keeps them active without the need for structured exercise, which promotes strength, mobility, and longevity.
In Okinawa, Japan, the term "ikigai" refers to having a sense of purpose in life. It’s about finding joy and fulfillment in life through intersecting what you love, what you are good at, what the world needs, and what you can be paid for. Pursuing ikigai is linked to numerous benefits, including personal fulfillment, better decision-making, increased resilience, improved well-being, enhanced productivity, better relationships, lifelong learning, career satisfaction, and contribution to society (Durango School District, n.d.).
A similar concept exists in Nicoya, Costa Rica, known as plan de vida, or “plan of life.” For Nicoyans, however, it goes deeper than just a life plan; it is one’s soul’s purpose, a framework for cultural survival, and a reason they get up in the morning. Plan de vida focuses on individuals and communities defining their values and goals in efforts to serve their purpose, bring people together, and contribute to family, work, and social life.
Both ikigai and plan de vida foster longevity by encouraging a positive outlook and an active lifestyle. In fact, having a clear sense of purpose is said to be “worth up to 7 years of extra life expectancy” (Buettner & Skemp, 2016).
It is no secret that excess stress can lead to many health-related issues, such as chronic inflammation, depression, digestive issues, fatigue, and many more. This is why Blue Zone individuals have learned to incorporate downshifting into their lives. Downshifting refers to intentionally slowing down to create space to de-stress. In Okinawa, individuals take a few moments daily to remember their ancestors and loved ones. In Loma Linda, the Adventists pray and perform other religious rituals. In Ikaria, they take naps. And, in Sardinia, they often have happy hours.
The 80% rule, or hara hachi bu, is an Okinawan principle that refers to stopping eating when you are 80% full. It is a mindful eating practice that prevents overeating, supports healthy digestion, and contributes to longevity by lowering the risk of chronic diseases. Allowing for that 20% gap creates space for you to feel satisfied rather than stuffed, making it easier to avoid overconsumption and thus weight gain. When practiced consistently, this habit can lead to healthier body weight, improved metabolism, and ultimately greater longevity.
Plant slant refers to a diet that emphasizes more plant-based foods while still allowing for a moderate consumption of animal products. The core of the diet is centered around fruits, vegetables, legumes, nuts, and seeds. In Blue Zones, meats are consumed on occasion, and when they are, they are consumed in small serving sizes (3 to 4 oz portions). This type of diet has numerous health benefits, including improved cardiovascular health, improved gut health, reduced inflammation, reduced risk of chronic diseases, and increased longevity. In addition to this, a plant-focused diet can “improve glycemic, cholesterol, and blood pressure control, which can minimize the need for prescription drugs” (S. A., 2024).
Wine @ 5 is a Blue Zone rule that refers to drinking alcohol in moderation, specifically only having 1-2 glasses a day and with friends or with food. The key here is that individuals are focused more on the socialization aspect rather than the alcohol itself, making it easier not to overdo it.
The people you surround yourself with matter. Being with the right tribe of people, one that supports your values, goals, and sense of purpose, can boost productivity, create a shared vision, and foster healthier habits that can lead to a longer, more fulfilling life.
Putting family first not only creates deeper connections with your loved ones but also lowers the risk of disease and increases life expectancy. In Blue Zones, it is common for entire families to either live together or in proximity, a practice shown to reduce the risk of diseases and lower child mortality rates of those in the home (Buettner & Skemp, 2016). These communities also emphasize long-term commitment. This practice of committing to a life partner can add up to 3 years of life expectancy (Buettner & Skemp, 2016). Additionally, by investing in their children, parents create a cycle of care, ensuring that as they age, their children are more likely to provide support in return.
In Blue Zones, belonging refers to being associated with some sort of faith-based community. Consistently attending faith-based services has been shown to increase life expectancy, with studies showing that “attending faith-based services 4 times per month will add 4 to 14 years of life expectancy” (Buettner & Skemp, 2016). Beyond religious benefits, these communities foster strong social connections, which play a huge role in longevity and overall well-being.
History of the Zones
Now that you know what the Blue Zones are and the habits they embody, let’s get into the history of how these zones came about. The term “Blue Zone” came about in “a 2004 study of human longevity in Sardinia by Michel Poulain and colleagues” (Rowan & Rowan, 2024). A blue pen was used to identify communities of high longevity on the island. Following this study, Dan Buettner, a National Geographic Explorer and journalist, began expanding this theory, dubbing areas with exceptional longevity “Blue Zones.” Dan and other demographers began to find shared habits and patterns among these Blue Zone areas. This is where the “Power 9” came to life. Dan published many books on the insights of Blue Zones as he traveled and learned more about the regions. These books include The Blue Zones, The Blue Zones Solution, The Blue Zones Challenge, The Blue Zones American Kitchen, and Blue Zones Secrets. In addition to these books, the concept has grown in popularity, with “Blue Zones® now a trademark of Blue Zones, LLC, and reflect[ing] the lifestyle and the environment of the world’s longest-lived people” (S. A., 2024).
How to Go Blue
Alright, so how do we live like these Blue Zone people so that we can live to be 100 years old (or older!)? Incorporating movement within our daily lives and routines is step one. Whether that be through work, a social activity, hobbies, going to the gym, playing a sport, or really anything that gets your body moving consistently.
Step two is to establish a life purpose. This may come through your faith, work, passions, etc. If you don’t know, start by asking yourself, “What is my reason for waking up in the morning?”
Next up, we’ve got to de-stress, or “downshift.” This can be done through a variety of ways, but at the root of it is finding time within your day to reset. Taking a few minutes to pray or meditate. Getting some sunlight or time in nature. Napping. Social time with friends. The list goes on and on. Finding something that works for you and your schedule is what’s most important.
We’re moving, de-stressing, and working toward our life purpose… Now, it’s time to talk about eating right. What does that look like? In the Blue Zones, it means focusing on a majority plant-based, whole-foods diet while incorporating meat and fish in moderation and incorporating the 80% rule, or hara hachi bu, in eating until we’re 80% full, then stopping. Eating slowly and mindfully rather than mindlessly eating in front of a screen. The same principle applies to drinking: enjoying alcohol in moderation and emphasizing the social experience over the beverage itself. Applying these practices in your life can improve digestion, prevent overeating, support long-term health, and increase longevity.
Lastly, there’s the social aspect. People in Blue Zones are actively involved in their communities, often participate in faith-based organizations, and place a strong emphasis on prioritizing their loved ones. In spending quality time with family and friends, engaging in community activities, and being part of a close-knit group, we can build strong support networks that reduce stress, boost mental well-being, and even contribute to longer, healthier lives.
Conclusion
Blue Zones aren’t just about dieting; they represent a blueprint for a long, meaningful, fulfilled life. From moving naturally and prioritizing plant-based foods to cultivating a sense of purpose in life, managing stress, and making quality time for friends, family, and community, the habits of these areas show that longevity is about more than just years; it’s about the quality of life. By adopting these habits into our lives, we can live longer, healthier, and happier lives. The lessons of the Blue Zones remind us that longevity isn’t just a distant goal; it’s built every day through consistent and intentional choices.
