Blue Zones and longevity: a balanced review of the Power 9 lifestyle factors

This review examined the evidence behind nine lifestyle habits linked with long lives in several regions called Blue Zones. The researchers compared population studies and other research rather than running a new experiment. They found reasonable support for regular movement, strong social ties, a sense of purpose, mostly plant-based foods, and not overeating. Evidence was less certain for some specific claims, and the Blue Zones research can be affected by incomplete records and other differences between populations.

What this means for you: These habits are generally sensible, low-cost choices, but no single plan guarantees a longer life. Focus on regular activity, nutritious food, relationships, sleep, and avoiding smoking rather than buying products marketed as a Blue Zones shortcut.
