Longevity Habits: What People Who Live to 100 Have in Common
Research from Blue Zones — the world's longest-lived populations — reveals consistent lifestyle patterns that predict exceptional longevity. Here's what they share and how to apply it.
Medically reviewed by Dr. Sarah Chen · Editorial Policy
Centenarians — people who live to 100 or beyond — are the fastest-growing demographic in the developed world. In the United States, the number of centenarians has grown from approximately 32,000 in 1980 to over 100,000 today. Researchers studying these populations have identified consistent behavioral and environmental patterns that appear to drive exceptional longevity.
The most comprehensive research comes from the Blue Zones — five geographic regions where people live measurably longer, healthier lives: Sardinia (Italy), Okinawa (Japan), Nicoya (Costa Rica), Icaria (Greece), and Loma Linda (California). Researcher Dan Buettner, in collaboration with the National Geographic Society and longevity researchers, identified nine common lifestyle factors across all five zones.
The 9 Common Factors of Longevity (Power 9)
1. Natural movement. Blue Zone centenarians don't run marathons or go to gyms — they live in environments that require constant low-level physical activity. They garden, walk to destinations, and do manual tasks. The lesson: build movement into your daily environment rather than relying solely on scheduled exercise.
