Across the world, a handful of communities have stood out for their extraordinary longevity. From the mountains of Sardinia to the islands of Okinawa,…
Sardinia, Italy | One of the world’s strongest concentrations of male centenarians was found in Sardinia’s mountainous villages. Natural movement, a plant-heavy traditional diet, beans and whole grains, strong family ties and close-knit communities are among the characteristics associated with longevity. (Image: Canva)
Okinawa, Japan | Okinawa was historically known for exceptionally high longevity, particularly among women. A traditional diet rich in vegetables, sweet potatoes and soy, along with daily movement, strong social networks, family ties and a sense of purpose, are key features of the Okinawan way of life.

What do Blue Zones have in common? Natural movement, plant-rich diets, strong social connections, family, purpose and lower stress are common threads across the five regions, although modernization has weakened longevity advantages in some areas, particularly Okinawa.
The five places featured are the traditional Blue Zones identified through Dan Buettner’s research. Their lifestyle patterns are associated with longevity, but do not by themselves prove cause and effect.
