Are you looking to improve your lifestyle and extend your life expectancy? Look no further than the world’s five blue zones. These are regions around the world that have been identified as having a higher-than-average concentration of centenarians, people who live to be over 100 years old. It is interesting to note that not only do large numbers of people in these communities live incredibly long lives, but they also enjoy excellent health for most or all of their lives. What are the 5 Blue Zones?

1. The Nicoya Peninsula in Costa Rica

The Nicoya Peninsula in Costa Rica is one of the five world-renowned blue zones with old age people. The term ‘blue zone’ refers to regions around the world where people live longer, healthier lives than anywhere else on earth. Located in the country’s northwest corner, the Nicoya Peninsula is home to some of the oldest human inhabitants on record and has long been recognised for its exceptional longevity.

The area is particularly notable for its high rate of centenarians — individuals over 100 years old — which far surpasses global averages. Researchers attribute this to a combination of factors, including generally good health practices, healthy diets that are rich in protective nutrients like antioxidants and omega-3 fatty acids, an active lifestyle with plenty of physical activity outdoors, and a life concept called Pure Vida.

Pura Vida ethos, deeply rooted in Costa Rican culture, embodies a philosophical approach to a life characterised by simplicity, contentment, and a relentless pursuit of happiness. Translating to “Pure Life,” this concept encourages individuals to slow down, embrace the present moment, and focus on cultivating meaningful relationships and cherishing the small things in life.

2. Okinawa Island in Japan

Located in the East China Sea, Okinawa has approximately 1.3 million inhabitants, many of whom live an exceptionally healthy lifestyle and enjoy an abundance of fresh produce grown on their own land.

The Okinawans are renowned for their longevity, with some living to be well over 100 years old, and this is largely attributed to their traditional diet which consists mainly of plant-based foods such as sweet potatoes and other root vegetables. It’s also thought that the islanders’ spiritual beliefs help them maintain a positive outlook on life and reasons for living longer than average. Moai principle, or life force, is an important part of the people s belief system and is also thought to help them live longer than others. The Okinawans believe that the life force must be kept strong in order to stay happy and healthy.

3. Sardinia Island in Italy

In addition, Sardinia’s beautiful Mediterranean climate, rich cultural traditions, and low levels of stress all contribute to the longevity of its residents.

Loma Linda is a small community of Seventh-day Adventists in southern California where life expectancy for men and women is almost 10 years higher than in the rest of America. The vegetarian population is also less likely to suffer from high blood pressure and heart disease, which contributes to their long lifespan. 

The community’s focus on holistic wellness, combined with its close-knit social structure, creates a supportive environment for its residents to live a healthy and long life.

5. Ikaria Island in Greece.

With a population of 10,000, Ikaria is the Greek island with the highest number of 90-year-olds. The island’s inhabitants live longer than anyone else in Europe and have one of the lowest rates of cancer, heart disease, cardiovascular disease, and dementia in the world. 

This longevity is often attributed to the island’s relaxed pace of life, healthy diet, and strong social support networks. The Ikarians consume a diet rich in olive oil, fresh fruits, and vegetables, and have a low consumption of meat and dairy products. Additionally, stress levels are low and there is a strong sense of community on the island, with residents regularly coming together for communal meals and social events.

What are the characteristics that allow these communities to have a long life span? 

  • Plant-based diets in a big proportion
  • Low levels of stress (e.g. meditation, yoga)
  • Little alcohol consumption
  • Active lifestyles (e.g. walking, gardening)
  • Community support (e.g. church, social clubs)
  • Good sleep habits (e.g. no TV in bedrooms)
  • Being present each day
  • Slowing down

Overall, these communities share a commonality of embracing life and positive outlook on life.

Although there are not enough studies to confirm what Dan Buettner observed and wrote about in his best-selling book The Blue Zones, there are studies showing that only 25% of human longevity is determined by genetics, and the other 75% is determined by lifestyle, including here not only diet but the way we spend our time, what we do and don’t do, how do we see life and what choices are we making on a daily basis. Like choosing every day to enjoy life.

If you haven’t yet, now is the time to read the bestselling book titled The Blue Zones of Happiness by Dan Buettner, about these 5 areas. The book shows how we can all learn from these communities and make lifestyle changes that will help us live longer and healthier lives.
