Blue zones: the secrets of longevity

Blue Zones are regions of the world where people live significantly longer than the global average. These zones have been identified through demographic studies and longevity research. Here's an overview of the Blue Zones and the factors that contribute to the longevity of their inhabitants.

1. What is a blue zone?

The term "blue zone " was popularized by Dan Buettner, who studied the areas where people live the longest and wrote several books on the subject. According to an article by Observatoire de la Prévention, the five blue zones identified are :

• Sardinia (Italy): Known for its high concentration of centenarians, particularly in the province of Nuoro.
• Okinawa (Japan): The inhabitants of this island have one of the highest life expectancies in the world.
• Ikaria (Greece): This island in the Aegean Sea is famous for its low rate of chronic disease and the longevity of its inhabitants.
• Nicoya (Costa Rica): The inhabitants of this peninsula have a high life expectancy and a low rate of chronic disease.
• Loma Linda (California, USA): This community of 9,000 members of the Seventh-day Adventist Church lives on average 10 years longer than other Americans.

2. Longevity factors

Inhabitants of blue zones don't live longer thanks to disease-protecting genes, but thanks to healthy lifestyle habits. Through an in-depth study of these five Blue Zones, researchers have identified common factors favoring longevity:

- Regular physical activity:

Inhabitants of blue zones naturally incorporate physical activities such as walking and gardening into their daily lives. Their occupations (shepherds, farmers, etc.) expose them less to a sedentary lifestyle. They are therefore less likely to develop diseases such as obesity or cancers(breast cancer, colorectal cancer).

- A healthy diet: Blue Zone residents consume large quantities of vegetables and fruit that they grow themselves. Their consumption of meat, alcohol and processed foods is moderate. They also favor legumes and whole grains. In addition, their food portions are moderate, limiting their calorie intake.

- A strong social bond :

Residents spend a lot of time with family and friends, and maintain strong intergenerational relationships. The elderly are often cared for by their families, which limits their isolation. The family plays a central role in their daily well-being.

- Controlled stress: Another common factor among Blue Zone residents is their low stress levels. Regular practice of relaxation techniques such as meditation, prayer or simply regular moments of relaxation enable them to effectively reduce stress.

- Meaning in life: Blue Zone residents find purpose in their lives, often through their commitment to spirituality or religion, which gives them a direction to follow.

The Blue Zones offer valuable lessons on how to live longer and age healthier. By adopting certain aspects of their lifestyle, we can all hope to improve our quality of life and longevity.
