Blue Zones are regions where people live the longest, healthiest lives, thanks to plant-rich diets, daily natural movement, strong social ties, and a sense of purpose. Found in Okinawa (Japan), Sardinia (Italy), Ikaria (Greece), Nicoya (Costa Rica), and Loma Linda (USA), these communities share common lifestyle patterns that reduce chronic disease and boost longevity. Their approach emphasizes simple, whole foods, regular activity, rest, and deep connections—habits that anyone can adopt to improve health and extend lifespan.
