Tea Traditions Across the Blue Zones
The Blue Zones are five distinct areas across the globe where people consistently live longer than average. These regions—Okinawa, Japan; Sardinia, Italy; Nicoya, Costa Rica; Ikaria, Greece; and Loma Linda, California—are defined by nine common lifestyle characteristics, including a largely plant-based diet. While the specific ingredients vary, a commonality is the consumption of tea or herbal infusions, suggesting this daily ritual plays a subtle but significant role in their longevity. The practice goes far beyond simple hydration, often integrating local, nutrient-rich herbs into a social or mindful routine.
Okinawa, Japan: Green Tea and Turmeric
In Okinawa, green tea is a staple of the daily diet and is consumed throughout the day. This practice contributes to their reputation for exceptional longevity. Okinawans drink a local variety of jasmine green tea called sanpin-cha, and also regularly consume tea made from turmeric, a powerful anti-inflammatory and antioxidant. Research associates green tea consumption with a lower risk of cardiovascular disease, stroke, and certain cancers. The tea-drinking ritual is often a social occasion, providing a moment of calm and connection with friends or family, which is another cornerstone of Blue Zone living.
Ikaria, Greece: Wild Herbal Infusions
The Greek island of Ikaria is known for its high number of nonagenarians and centenarians, as well as exceptionally low rates of dementia. A key part of the Ikarian diet is the daily consumption of herbal teas made from wild-picked local plants. Instead of conventional tea leaves, Ikarians brew infusions from herbs like rosemary, wild sage, oregano, and dandelion. Pharmacological analysis has revealed these herbs contain anti-inflammatory and diuretic properties, which can help lower blood pressure, a known risk factor for dementia. The act of foraging for these herbs adds a physical activity component to their daily ritual.
Nicoya, Costa Rica: Local Herbal Blends
Residents of the Nicoya Peninsula in Costa Rica, another Blue Zone, also regularly consume herbal infusions made from native plants. Local herbs, sometimes considered weeds, are harvested and brewed into teas brimming with micronutrients. Brands like Blue Zones Nicoya offer varieties featuring maya nut and cinnamon, or hibiscus, reflecting the region's rich flora. Maya nut, for example, is recognized as a superfood rich in antioxidants. These caffeine-free infusions support overall wellness and are part of the daily life that contributes to the Nicoyans' long lifespan.
Sardinia, Italy: Milk Thistle and Other Herbs
On the Italian island of Sardinia, another Blue Zone with a high concentration of male centenarians, milk thistle tea is a traditional beverage. Milk thistle is known for its liver-supporting properties. Beyond this, local herbal tea blends incorporating myrtle, lemon thyme, and lavender are common. These infusions are part of a larger, family-oriented Mediterranean lifestyle that emphasizes whole foods, moderation, and close social ties.
Loma Linda, California: A Different Approach
The Blue Zone in Loma Linda consists largely of Seventh-day Adventists, a community whose longevity is linked to a different set of dietary rules. Their diet is predominantly vegetarian or vegan and emphasizes water consumption. While tea shops exist in the area, traditional tea rituals are not a prominent longevity habit in the same way they are in other Blue Zones. Many Adventists abstain from caffeinated beverages, including traditional teas and coffee, though some may consume decaffeinated options.
Health Benefits of Blue Zone Tea Consumption
The diverse tea traditions of the Blue Zones offer a range of health benefits, reinforcing the idea that simple, consistent habits can have a profound impact on long-term health. These benefits can be categorized as follows:
- Antioxidant Power: Green tea (Okinawa) and Ikarian herbal infusions are rich in antioxidants, which combat free radicals and reduce cellular aging.
- Anti-inflammatory Effects: Turmeric (Okinawa) and Ikarian herbs like sage and rosemary possess potent anti-inflammatory properties, which help protect the body against chronic diseases.
- Cardiovascular Health: Green tea has been linked to a reduced risk of heart disease, while diuretic Ikarian teas help manage blood pressure.
- Cognitive Function: Studies suggest that herbal tea consumption, particularly in Greece, can be linked to improved cognitive performance in older adults.
- Digestive Health: Herbs used in Ikarian teas, such as sage and mint, are known to aid digestion. Milk thistle in Sardinia is also known to support liver health.

The Ritual of Tea: More Than Just the Drink
While the specific compounds within each tea offer distinct health benefits, the ritual surrounding its consumption is equally important. In Blue Zones, the act of drinking tea often involves pausing for a moment of quiet reflection or socializing with others. This practice naturally reduces stress and provides a sense of purpose and connection, which are two powerful contributors to longevity. In Okinawa, the afternoon tea ritual provides daily downtime, while in Ikaria, the foraging and brewing process connects people to nature and tradition. This holistic approach—combining healthy ingredients with mindful, social routines—highlights that longevity is a product of lifestyle, not just diet alone. The tea is merely a focal point for these larger, life-affirming habits.
Conclusion: The Wisdom in a Warm Cup
Do people in Blue Zones drink tea? The answer is a resounding yes, though the specific type of tea varies dramatically by region. From the green tea of Okinawa to the wild herbs of Ikaria, these longevity hotspots incorporate specific, beneficial teas and infusions into their daily routines. These beverages are not just passive thirst-quenchers; they are integral to a lifestyle that promotes long-term health. The benefits—from powerful antioxidants to anti-inflammatory effects—are significant, but the mindful and social rituals surrounding tea consumption are just as vital to the well-being of Blue Zone residents. Embracing these simple, purposeful traditions offers a taste of the Blue Zone secret to a longer, healthier life.
