What Are the Blue Zones—and Why Do They Matter?
Blue Zones are regions of the world known for high longevity, where people live significantly longer and healthier lives. The term "Blue Zones" was coined by Dan Buettner, a National Geographic Fellow, who identified the following five regions as Blue Zones (see Blue Zones map below):
Ikaria, Greece
Okinawa, Japan
Ogliastra Region, Sardinia, Italy
Nicoya Peninsula, Costa Rica
Loma Linda, California, United States (specifically, the Seventh-day Adventists community)
These are the five Blue Zone areas featured in the Netflix series, where researchers have documented extraordinary longevity.

Blue Zones have attracted attention from researchers and health experts due to the unusually high number of centenarians (people who live past 100 years) living there and due to the relatively low rates of age-related diseases such as cancer, heart disease, diabetes, or dementia. People in Blue Zones live longer and healthier lives, often surpassing 100 years, with lower rates of chronic diseases.
Given the choice, many of us would wish for eternal life, but in its absence, we can at least strive to live as healthy and long as possible. It’s nice that the show not only focuses on the lifespan (how long we live), but also focuses very strongly on the healthspan—highlighting how unusually healthy and active these centenarians are.
The 4-episode Netflix series Live to 100: Secrets of the Blue Zones—available to stream on Netflix—follows longevity expert Dan Buettner as he visits the Blue Zone regions to unveil some of the “secret” lifestyle and cultural factors that may be behind the longevity of their residents. The Netflix show showcases remarkable Blue Zones centenarians who are still active and vibrant in their 100s. Some of them are still working (some are riding horses!); but above all, most of them look very happy.
The Blue Zones research draws on decades of demographic data, field studies, and epidemiological work conducted in collaboration with institutions such as National Geographic and academic public-health researchers.
In this post, we distill the core longevity patterns highlighted in Netflix’s Live to 100 and place them in a broader evidence-based context—focusing on habits that consistently show up across regions, cultures, and decades of research.
Rather than chasing longevity hacks, the series highlights how simple, repeatable lifestyle patterns—when embedded into daily life—can quietly compound into longer, healthier lives.
The Blue Zones Netflix series not only entertains but offers practical longevity tips we can all adopt.
8 Longevity Lessons from Netflix’s Blue Zones: How to Live Past 100
In Blue Zones, people don’t just live longer—they often stay active, social, and mentally sharp well into their 90s and beyond.
Rather than promising a single “secret” to reaching 100, the Netflix series highlights a small set of everyday habits that consistently support both lifespan and healthspan.
Below are eight of the most practical lessons from the show, followed by a deeper look at the specific factors observed in each Blue Zone region.
1. Sense of Purpose and Outlook on Life.
Centenarians living in Blue Zones tend to have a positive outlook on life. They have a sense of purpose and belonging that is crucial for their mental well-being. They are typically focused on family, friendships, faith, and work that is meaningful to them.
The show presented proud centenarians showing off their craft in Okinawa (their “ikigai”) or still riding their horses while herding cattle in Nicoya (Costa Rica). Faith was important to many of them—the show presents elders in different locations regularly attending their faith congregations. But most importantly, their positive outlook on life and sense of purpose is grounded in the heart-felt respect and love provided by their family and community.

2. Move Naturally.
The physical activity of Blue Zones inhabitants doesn’t necessarily have to be a formal exercise routine. With the exception of Loma Linda Adventists, who do practice sports, physical activity is generally incorporated organically into their daily routines.
They constantly engage in activities like walking, gardening, dancing, or manual labor, which keep them very active without the need of formal workouts. Incorporating movement into daily routines helps maintain mobility and overall health. Residents in Blue Zones often live in steep, hilly areas or use low furniture, both of which promote natural physical activity and strengthen lower body muscles, contributing to their longevity.
3. The Power of Community.
Close social bonds are essential in Blue Zones for reducing stress and promoting longer lifespans. Strong social connections in Blue Zones communities play a vital role in their longevity and overall well-being that stood out in relation to how our modern society is typically structured.
People in these communities maintain strong ties within their community, and often go a step further to form formal, tight-knit support networks (e.g., Japanese Moai—small lifelong social groups in Japan that provide emotional and practical support).
Regular social interactions contribute to emotional stability, stress reduction, and a sense of belonging, which are vital for longevity. A study published in the American Journal of Public Health in 2018 found that loneliness was associated with a 50% increased risk of early death. This is very worrisome, given that nearly half (46%) of American adults report sometimes or always feeling lonely, according to a survey conducted by Cigna in 2018.

4. Family First.
In Blue Zones communities, the concept of “family first” is very ingrained in their lives, emphasizing the important role of family ties in promoting well-being and longevity. In Blue Zones, multi-generational households are common and contribute to the emotional health and longevity of their residents, with children, parents, and grandparents often living together, helping each other, and producing strong intergenerational relationships.
By prioritizing family relationships and investing in the well-being of loved ones, older individuals in Blue Zone communities cultivate a source of emotional resilience and social support that contribute to their overall health and longevity.
5. Actively Focus on Others.
As we’ve written in a previous post, one of the ultimate sources of a meaningful and happy life lies within ourselves and having a greater sense of responsibility and concern for others. Focusing on others, a common practice in Blue Zones, is a proven strategy to reduce negative emotions and boost happiness and to increase your well-being.
This is illustrated prominently throughout the show—whether it is the Loma Linda adventists regularly volunteering in communities nearby or the responsibility that elderly citizens are granted for taking care of the younger generations in Okinawan and Singaporean households.
6. Stress Reduction.
Unsurprisingly, effective stress management is a critical factor in the longevity of Blue Zones residents, helping them live calmer, longer lives. Individuals in Blue Zones develop coping mechanisms and lifestyle practices around physical activity and social interaction that mitigate stress.
For Loma Linda Adventists, there is a formal emphasis on rest and relaxation that includes a weekly day of rest (the Sabbath—a dedicated day free from work and routine obligations). But more generally, elderly folk presented in the show do not appear stressed.
Experts interviewed emphasized the role that technology has in keeping us aware in real time of troubling events that are going on around the world, over which we have no agency. In contrast, consider the mental stability and calmness that arises from local sheepherders in Sardinia when they manage to focus and resolve the problems that arise for them each day. The takeaway is to focus on things within your control.

7. Eat Wisely.
The Netflix show presents the Blue Zone diet for longevity as being primarily plant-based, focusing on nutrient-rich whole foods like fruits, vegetables, grains, and legumes for longevity as important contributors to overall health and longevity. Do Blue Zones eat meat? Yes—but only in small portions, typically a few times per month, and often as part of celebrations. Do Blue Zones drink coffee? Also yes—moderate coffee and herbal tea consumption is common, often as part of social rituals.
Although they consume meat very sparingly, the focus is on smaller portions of lean proteins. In addition, they incorporate dietary staples like nuts, seeds, and healthy fats such as olive oil. Surprisingly, Sardinian residents ate a substantial amount of carbohydrates; it likely helps to focus on consuming “good carbs” in moderation, i.e., those that present lower glycemic indexes (think of sourdough, rye, buckwheat, or pumpernickel bread).
Importantly, it’s not only about what you eat, but how much: calorie control, such as the Okinawan practice of “hara hachi bu”, is a vital principle for longevity. It involves stopping eating when you are approximately 80% full, and followers of this practice consider it a key factor contributing to their longevity.
Modern approaches like algorithmic living echo this principle by creating personal rules that automate healthy decisions—helping you bypass willpower battles and align daily dietary habits with long-term health goals.
8. The Environment Matters.
In Blue Zones, the surrounding environment plays a quiet but powerful role in longevity. These regions typically offer clean air, access to nature, and walkable daily living—conditions that naturally encourage movement, reduce stress, and support long-term health.
Rather than relying on willpower alone, residents benefit from physical environments that make healthy behavior the default, from routine outdoor activity to calmer, lower-stress lifestyles.
