Scientists Identified 'Blue Zones' Where People Live Beyond 100. Then They Found Why.

Did you know that our planet Earth has certain regions where people tend to live longer? Known as “Blue Zones,” the unusual phenomenon was first spotted by Michel Poulain (University of Louvain) and Gianni Pes (University of Sassari) in 2004.

In these life-supporting Blue Zones, an average human being lives for over 100 years. This is well beyond the average life expectancy for humans observed by the World Health Organization (WHO) at 73.4 years in 2019.

Where are the Blue Zones?

Outlined in an article published in Experimental Gerontology, the name for such regions was coined by Poulain and Pes based on the colour used by both scientists to identify such areas, including the Nuoro province on the island of Sardinia in Italy.

Dan Buettner, an American author was also working on Blue Zones in 2005. According to Interesting Engineering, Buettner had identified five Blue Zones around the world by April 2015: Sardinia in Italy, the islands of Okinawa in Japan, Nicoya Peninsula in Costa Rica, Ikaria in Greece, and Loma Linda in California.

Why do people in Blue Zones live longer?

Think it is due to genes? Climate? Think again! Scientists found nothing peculiar in the DNA of people in these regions to assert their long-life. Instead, they shared one characteristic – geographical isolation.

Most regions that are geographically isolated also have less fast food, processed food, and diet-rich foods to reach these regions. Essentially, diet and exercise are responsible for the long-life of people in Blue Zones.

Scientists have made a list of factors that help in living a longer life. First off – having goals and purpose. To add to it, scientists suggest having a support network of family and friends. Reducing stress and stopping consumption of food when you’re 80 per cent full are also contributing factors.

Drink alcohol too often? Consume it in moderation and throw some exercise in the mix, and you’re almost living in one of these Blue Zones.
