    Blue Zones

    The Blue Zones Power 9

    Nine habits shared by the world's longest-lived communities — Okinawa, Sardinia, Nicoya, Ikaria and Loma Linda. Each one explained plainly, with how to apply it and honest sources.

    1. Move naturally
    Sardinia, Ikaria, Okinawa
    The longest-lived people don't "work out" — they live in environments that nudge them into constant, low-intensity movement: gardens to tend, hills to walk, bread to knead, few labour-saving machines.
    2. Know your purpose
    Okinawa (ikigai), Nicoya (plan de vida)
    A clear reason to get up in the morning — the Okinawans call it ikigai, the Nicoyans plan de vida. It is a felt sense that you are needed and that your days matter.
    3. Downshift stress
    All five Blue Zones
    Centenarians feel stress like anyone else, but their days have built-in rituals that release it: a nap, a prayer, a happy hour, ancestor remembrance.
    4. The 80% rule (Hara hachi bu)
    Okinawa
    Okinawans say "Hara hachi bu" before meals — a reminder to stop eating when about 80% full, leaving a margin rather than eating to fullness.
    5. Plant slant
    All five; strongest in Loma Linda & Okinawa
    Diets are overwhelmingly plant-based — beans, greens, whole grains and nuts at the centre; meat eaten rarely, in small portions.
    6. Wine at 5
    Sardinia, Ikaria (not Loma Linda)
    In several (not all) Blue Zones, people drink alcohol moderately and regularly — typically 1–2 glasses of wine with food and friends.
    7. Belong (faith community)
    All five Blue Zones
    Nearly all centenarians interviewed belonged to a faith-based community and attended regularly — the denomination mattered less than the belonging.
    8. Loved ones first
    All five Blue Zones
    Successful centenarians put family first: ageing parents and grandparents kept close, a committed life partner, and time invested in children.
    9. Right tribe
    Okinawa (moai), all five
    The world's longest-lived people chose — or were born into — social circles that support healthy behaviours. Okinawans form "moais": groups of friends committed to each other for life.
