Dan Buettner has studied five places around the world where residents are famed for their longevity: Okinawa in Japan, Nicoya in Costa Rica, Icaria in Greece, and Loma Linda in California and Sardinia in Italy.
People living in these so-called “blue zones” have certain factors in common – social support networks, daily exercise habits and a plant-based diet, for starters. But they share another unexpected commonality. In each community, people are gardening well into old age – their 80s, 90s and beyond.
It is well documented that spending time outdoors along with moderate physical activity is linked to longer life, and gardening is an easy way to accomplish both. “If you garden, you’re getting some low-intensity physical activity most days, and you tend to work routinely,” says Buettner. He adds there is evidence that gardeners live longer and are less stressed.
