“Blue zones” are specific geographic areas in the world where people have a higher life expectancy and tend to live beyond 100 years in greater proportion than in other parts of the planet. These zones were identified from studies conducted by researcher Dan Buettner and his team, who examined the common factors among long-lived communities.

The five most recognized “blue zones” are:

1. Okinawa, Japan: The inhabitants of Okinawa are known for their diet rich in vegetables and tofu, as well as their strong sense of purpose known as “ikigai.”
2. Sardinia, Italy: Specifically, the region of Barbagia in Sardinia has a high concentration of centenarian men, attributed to their Mediterranean diet and active lifestyles.
3. Nicoya, Costa Rica: The Nicoyans have a diet based on corn, beans, and squash, and maintain strong family and community ties.
4. Ikaria, Greece: The inhabitants of Ikaria have a diet rich in vegetables, legumes, and olive oil, and practice regular fasting.
5. Loma Linda, California, USA: The Seventh-day Adventist community in Loma Linda has healthy lifestyle habits, including a vegetarian diet and the observance of the Sabbath as a day of rest and spiritual renewal.

The common characteristics among the “blue zones” include:

• Healthy diet: High in plants, with low consumption of meat and processed foods.
• Regular physical activity: Naturally incorporated into daily life, such as walking, gardening, and manual work.
• Strong social connections: Solid family and community ties.
• Sense of purpose: Having a clear purpose in life.
• Stress management: Techniques and rituals that help reduce stress.

These practices contribute to longevity and a healthier life in the “blue zones.”
