What Are the Blue Zones?

If you’re interested in longevity, lifespan, or general health and wellness, you may have heard some bits and pieces about the ‘Blue Zones’ of earth. Identified by researcher Dan Buettner, the Blue Zones have been defined as the regions that are home to residents with drastically lower rates of chronic diseases, and longer life expectancy. 

As technology increases, so too does our ability to learn and understand information about different cultures, lifestyles, and trends. Combine that with an innate desire to live longer and a global wellness boom, it’s no surprise the Blue Zones have captured the world’s attention.

At Mana, we’re all about combining science with traditional methodology. As a longevity, science-driven recovery and wellness retreat, our foundations are built on evidence-based methodology to learn more about health. And the Blue Zones? They’re one of the most compelling real-world examples of evidence in action.

A Blue Zone is a place where people simply live longer – and better. 

‘Blue zone’ is a term that has been coined to represent a geographic area where residents live statistically longer than the rest of the world. Generally speaking, these areas have an unusually high number of people who live to be 100, or older. 

National Geographic Explorer and Research Dan first started writing about the concept back in 2004, following an expedition to Okinawa, Japan to research the areas with the highest concentrations of centenarians. From there, the expedition evolved into the discovery of five main regions where people consistently live over 100 years old.

According to Dan, there are five main ‘Blue Zones’ in the world: 

1. Ogliastra, Sardinia, Italy
2. Okinawa, Japan
3. Nikoya, Costa Rica
4. Ikaria, Greece
5. Loma Linda, California, USA

Each of these locations has been identified as not only having an exceptionally high life expectancy, but the residents are living lower rates of heart disease, cancer, and diabetes. 

The numbers tell a clear story. The average life expectancy in Australia is 81.1 years for men and 85.1 for women – and 79 in the US. The gap between the rest of the world and a Blue Zone centenarian isn’t just years. It’s vitality.

The lifestyle of the residents in the Blue Zones underpins the foundations of why (and how) each community member is expected to outlive the average person. 

Yes – genetics matter. But the Blue Zones are proof that how you live is just as powerful as what you’re born with.

The Blue Zones concept has identified nine common traits that each of these areas have in common, that are proven denominators among the residents living longer. Each of these ‘lessons’ is science-backed – and each one is within reach.

There are specific elements that are unique to each location that likely contribute to good health – for example, residents of Ikaria are known to rely heavily on a Mediterranean diet, rich in olive oil, red wine, and home grown vegetables. Okinawa, on the other hand, is home to the world’s oldest women, who consume a lot of soy-based foods and practice ancient martial arts like Tai Chi. 

That being said, there are a lot of shared elements. Here are the main ‘lessons’ or ‘powers’ of the Blue Zones that are directly tied back to longevity.

Each of the communities in the Blue Zones share some concept of movement. Sardinian Shepherds walk up to 8-10 kilometres per day; Ikarians exercise mindlessly by just gardening, walking to their neighbour’s house, or general yard work; and Nicoyans stay active through physical labour and farming well into old age. Okinawans practice Tai Chi and tend their gardens daily, and the Adventists of Loma Linda are known for regular nature walks.

In Okinawa, it’s known as ‘Ikigai’, in Nicoya, they call it ‘plan de vida’. Both translate to ‘why I wake up in the morning’. In each of these Blue Zones, the residents have a deep sense of purpose and contribution, something that is intrinsically linked to living a long, healthy life.

Yes – even on a remote Mediterranean island, it’s possible to experience stress! But the Blue Zone research shows that the people of these communities have intense de-stress regimes – Adventists of Loma Linda pray, Ikarians take an afternoon nap, Sardinians practice happy hour, and Okinawans take a few moments each day to remember their ancestors.

Food in the Blue Zones is grown, shared, and eaten with intention – not tracked, rushed, or consumed alone. And it’s largely plant-based. Beans – fava, black, soy, and lentils are included in most centenarian diets, and meat is only consumed a few times per month.

The Sardinian diet consists of whole-grains, beans, vegetables, fruits, and less than 5% meat, fish and poultry. A glass of goat’s milk contains components that are said to protect against inflammatory diseases. The Nicoyan diet is known for being light – particularly when it comes to dinner, enjoying a traditional Mesoamerican diet with plenty of squash, corn, and beans. In Okinawa, the diet shared by residents is inherently plant-based, with plenty of tofu and home-grown vegetables. And the Loma Linda residents are part of the Seventh-day Adventist church, where they stick to a vegetarian diet. 

The ‘Power 9’ lessons from Dan also include the 80% rule – where you stop eating when your stomach is 80% full.

Interestingly, people in all Blue Zones, except Adventists, drink alcohol pretty moderately every day – consuming an average of 1-2 glasses of wine each day with friends and food. The difference is that this is a daily ritual, rather than over-consumption on the weekends.

Research consistently shows that loneliness and social isolation are as damaging to health as smoking 15 cigarettes a day. Something shared by all five Blue Zones is an innate sense of belonging and community. Each area has cultivated deep social ties that extend well beyond the family unit – connection isn’t incidental, it’s a way of life.

Ikarians are known to foster strong social connections through regular gatherings, shared meals, and a culture where neighbours genuinely look out for one another. In Okinawa, Japan, there is a strong dedication to friends and family, with a powerful social network called moai – a close-knit group of lifelong friends who support each other emotionally and financially, which is maintained long into old age. In Sardinia, the tight-knit village structure means that elders are never isolated; they remain active, respected participants in daily community life.

What makes the Blue Zones so fascinating is that the principles are so simple. There’s nothing outwardly radical. They’re moving daily, eating well, resting deeply, and staying connected to something meaningful.

The principles that keep the longest-living communities thriving are the same ones that we know are important.

At Mana Sanctuary, our retreats, including our longevity & lifespan pathway, are designed for guests who want to put these principles into practice. Where Okinawans decompress through daily ritual, Mana guests have the Satori Brain Gym and daily sleep rituals. Where Blue Zone communities eat with intention, our resident chef prepares protein-forward, nourishing meals designed for longevity. The tools look different. But the outcome is the same.
