In some areas of the world people live not only longer but longer in good health, with a surprising number of centenarians who are still active, alert and independent. These are the so-called Blue Zones, a concept that has entered everyday language thanks to the work of researcher and writer Dan Buettner, who deserves credit for turning a demographic observation into a model accessible to everyone.

In the book The Blue Zones, published by National Geographic in 2008, Buettner studied particularly long-lived communities in Sardinia, Okinawa, Icaria, Nicoya and Loma Linda. The value of that work lies in having isolated common and replicable habits, transferable beyond those specific places. Let us look at the seven most solid secrets, read in the light of the most recent scientific research, to understand what is really transferable into everyday life.

Natural movement and constant activity

In the Blue Zones no one attends a gym: people move because life requires it, by walking, farming, climbing slopes, performing manual and household work. This natural and continuous movement is the first secret, and it is very different from the intense but sporadic training that is often abandoned after a few weeks.

Research confirms this clearly: a 2023 study by Sun in the Journal of Sport and Health Science showed that replacing sedentary time with physical activity, even light, improves health outcomes. In turn, López-Bueno, in 2023 in The Lancet Healthy Longevity, associated leisure-time physical activity in older adults with lower mortality, including for causes linked to dementia. The body, after 65, asks for diffuse and daily movement rather than isolated efforts.

Purpose, slowness and the 80 per cent rule

The second secret is having a clear reason to get up in the morning, what in Okinawa is called ikigai. Cohen, Bavishi and Rozanski confirm it, in Psychosomatic Medicine in 2016, linking a clear reason to live to greater longevity: it is not poetry, it is a factor with measurable effects.

The third secret is stress management, with slower rhythms, real pauses and daily moments of decompression, not postponed to holidays. The fourth is the eighty per cent rule: stop eating when nearly full, not a complicated diet but a simple and sustainable measure at every meal. These are habits that mature easily where the day has a human rhythm and is not stuffed full of commitments by force.

Plant-based eating, community and belonging

The fifth secret is a mostly plant-based diet, with legumes at the centre of the plate and meat as the exception, not the daily rule. The sixth is the priority given to relationships, family and a circle of long-standing friends: the review by Vila published in Frontiers in Psychology in 2021 links social support to greater longevity, giving scientific basis to what the Blue Zones have practised for generations without calling it prevention.

The seventh secret is the sense of belonging to a community, which provides structure, recognition and continuity over time. Taken together, these secrets describe less a diet and more an entire living environment. It is no coincidence that Guild Living’s happy longevity proposal places community, rhythm and relationships at its centre, and not a single isolated trick to be applied with discipline.

The Blue Zones as a model of place

The most important point that emerges from Buettner’s work is that longevity is not the result of a single heroic gesture, but of an environment that makes the right choices easy. In the Blue Zones extraordinary discipline is not required: context does most of the work, because moving, eating well and being together are the most convenient and natural way, not the most strenuous to impose on oneself every day.

What is really transferable to Italy

The Blue Zones are found in very specific contexts, and a legitimate question is how much of those secrets is replicable in the life of an over-65 in Italy. The answer is encouraging: most of it. Natural movement does not require the Okinawa countryside, but days in which walking, climbing stairs and doing manual activities are the norm and not the exception. The mostly plant-based diet largely coincides with the Mediterranean tradition, which is Italian food heritage even before being a scientifically recognised model worldwide.

Purpose, community and stress management are also transferable, on one condition: that there exists a tissue of relationships and a life rhythm that make them possible every day. This is where many individual paths get stuck, because in an isolated home it is hard to recreate community and rhythm alone. The most important transferable point, then, is not a single Sardinian or Japanese habit, but the underlying principle of Buettner’s work: design the environment so that healthy choices are the easiest. On this principle, and not on exotic imitation of a diet, it makes sense to focus when thinking about where and how to live the years after 65.

This is exactly the philosophy with which Guild Living designs its communities for over-65s: make movement, relationships, purpose and good nutrition daily without them becoming a burden to bear alone. The mild climate and natural settings, such as those of Guild Versilia on the Tuscan coast, closely echo the living environment of the longest-lived areas of the Mediterranean.
