Every tradition has its own vocabulary, and this journal leans on quite a bit of it: qi, yin and yang, wabi-sabi, hara hachi bu. Rather than re-explain each term inside every article that uses it, this page collects them in one place, defined plainly, with a link to wherever each one is explored in full.
Use it as a reference, not a reading assignment. Jump to a term below, or scan a whole section if a topic, food, practice, or a scientific idea, is new to you.
Chinese Medicine
Qi氣
The vital energy Chinese medicine treats as the basis of thought, movement and health, closer to "functional activity" than to spirit. Most traditional practice, from breathing exercises to acupuncture, is built around keeping it moving freely. See it applied in our guide to the Five Elements.
Yin and Yang
The two complementary forces Chinese medicine uses to describe foods, seasons and organs: yin is cooling, slow and inward, yang is warming, active and outward. Health is framed as keeping the two in a working balance, not eliminating one. See warming and cooling foods.
The Five Elements五行
Wood, fire, earth, metal and water: a framework used to group organs, emotions, seasons and temperaments into five interacting patterns. See the full explanation, or take the quiz to find your dominant element.
Shen神
The clarity and calm of the mind, traditionally tied to the heart. When shen is unsettled, the classic sign is racing thoughts and poor sleep rather than physical illness. See Sleeping Well: An Evening Ritual.
Jing精
The body's deep reserve, tied to the kidneys, closer to a savings account than daily income. Traditionally, overdrawing it through chronic exhaustion is considered one of the fastest routes to burnout. See Kidney Qi and Chronic Fatigue.
Wei Qi衛氣
The body's outer layer of defense, roughly analogous to immune resilience against cold, wind and seasonal illness. See Wei Qi and Cold and Flu Season.
Liver Qi Stagnation
The traditional description for qi that is not flowing smoothly through the liver system, associated with irritability, tension and a short fuse under stress. See Liver Qi Stagnation and Stress.
The Organ Clock
A traditional framework assigning each organ a two-hour window of peak activity across the day, used to time meals, rest and activity. See The Chinese Organ Clock.
Yang Sheng Practice
Yang Sheng養生
Literally "nourishing life": the broad tradition of daily practices, diet, movement, rest, meant to sustain long-term health rather than treat illness after it appears. See Nourishing Life: A Quiet Path to Wellbeing.
Wu Wei無為
"Effortless action": a Taoist principle of achieving more by forcing less, working with a situation's natural direction instead of against it. See Wu Wei: Effortless Action.
Qigong氣功
Slow, breath-coordinated movement practice aimed at cultivating and circulating qi, gentler and more meditative than most Western exercise. See a beginner's sequence, or how it differs from tai chi and yoga.
Gongfu Tea
A traditional brewing method using small vessels, short steeps and multiple infusions, treating tea preparation itself as a slow, attentive ritual rather than a means to an end. See The Gongfu Tea Method Explained.
Japanese Concepts
Ikigai
A Japanese term for one's reason to get up in the morning, sitting at the overlap of what you love, what you are good at, and what the world needs from you. See Ikigai Explained.
Wabi-Sabi
The aesthetic of finding beauty in imperfection, impermanence and age rather than polish, applied as much to a mindset as to an object. See Wabi-Sabi and the Beauty of Imperfection.
Hara Hachi Bu
The Okinawan practice of eating until about 80% full instead of completely satisfied, one of the most consistently cited habits behind the region's longevity. See the full guide, or try the interactive timer.
Moai
Lifelong Okinawan social support groups, often formed in childhood, that provide practical and emotional backup across an entire life, a structural buffer against loneliness and stress. See the Okinawan diet guide.
Shinrin-Yoku森林浴
Unhurried time spent in a forest, associated with measurable drops in stress hormones and increases in immune activity. See The Neuroscience of Forest Bathing.
Food & Fermentation
Umami
The fifth basic taste, a savory depth found in dashi, miso, aged cheese and mushrooms, driven largely by glutamate. See Dashi: The Umami Foundation of Japanese Cooking.
Koji
A mold culture used to ferment rice, soy and barley into miso, soy sauce and sake, the workhorse of Japanese fermentation. See our miso guide.
Dashi
The foundational Japanese broth, usually built from kombu and dried bonito flakes, that underlies most Japanese cooking the way stock underlies French cuisine. See the full guide.
Congee
A slow-cooked rice porridge eaten across East Asia, traditionally treated as gentle, easily digested food for mornings, illness or recovery. See Congee: The Quietest Breakfast in the World.
Lacto-Fermentation
The process behind kimchi, sauerkraut and traditional pickles, where naturally occurring bacteria convert sugars into lactic acid, preserving the food and producing its sour flavor. See how to start fermenting at home, or our kimchi guide.
Longevity Science
Geroscience
The scientific field studying the shared biological mechanisms of aging itself, rather than treating each age-related disease separately. See what geroscience says about traditional longevity practices.
Blue Zones
Five regions studied for unusually high numbers of centenarians: Sardinia, Okinawa, Ikaria, Nicoya and Loma Linda. The underlying data has real, ongoing scientific disputes worth knowing about. See what the five Blue Zones actually share.
Plan de Vida
The Costa Rican equivalent of ikigai, a stated reason for living used in Nicoyan Blue Zones research as a marker of long-term health outcomes. See the Blue Zones comparison.
Gut Microbiome
The trillions of bacteria living in the digestive tract, increasingly linked to immunity, mood and metabolism well beyond digestion itself. See Understanding the Gut Microbiome.
Circadian Rhythm
The roughly 24-hour internal clock governing sleep, hormones, digestion and alertness, kept on schedule primarily by light exposure. See the organ clock, or try the interactive light and rhythm tracker.
