Kapha

Kapha is one of the three doshas, the fundamental humours of Ayurveda. In its classical composition Kapha is formed chiefly of the elements earth and water, and it is the principle of structure and cohesion, governing the body's substance, lubrication, immunity, and stability, the moist and solid framework that holds things together. When balanced it gives strength, endurance, calm, and steady vitality; when disturbed it is associated in the tradition with heaviness, congestion, sluggishness, and excess weight. Each person's constitution (prakriti) combines the three doshas in a characteristic proportion, and Ayurvedic practice aims to keep them in balance through diet, exercise, and seasonal regimen.

Classical Ayurvedic literature divides Kapha into five subtypes: kledaka kapha, in the stomach, moistening food as digestion begins; avalambaka kapha, in the chest, supporting the heart and lungs; bodhaka kapha, on the tongue, carrying the perception of taste; tarpaka kapha, in the head, nourishing the sense organs and the brain; and shleshaka kapha, in the joints, providing their lubrication. Susruta, whose classical compendium is oriented toward surgery, gives particular attention to shleshaka kapha's role at the joints, while Caraka's internal-medicine text treats the fivefold division more evenly across all five seats, a difference of emphasis between the two texts rather than of underlying doctrine. These are the concepts of the Ayurvedic tradition, presented here as that tradition frames them.

Ayurveda distinguishes a person's prakriti, the constitutional balance of the three doshas fixed at conception, from their vikriti, the current state of imbalance shaped by diet, season and habit. A person whose prakriti is Kapha dominant is described in the classical texts as solidly built, calm and steady, prone to sluggish digestion, weight gain and lethargy when out of balance, traits treated as that person's baseline constitution rather than a disorder in themselves; the condition to treat is a Kapha vikriti that has grown past that baseline.

Seasonal regimen, or ritucharya, treats late winter and spring as the seasons when Kapha naturally increases in everyone, the season's cool, heavy, damp qualities mirroring the dosha's own, and classical practice recommends light, warm, stimulating food and vigorous activity at that time of year to keep Kapha from accumulating to excess regardless of constitution.

Kapha's association with steadiness and calm has made it a popular shorthand in commercial wellness marketing, where an online quiz assigns a single fixed dosha type in minutes; practitioners trained in the classical texts have criticised this as flattening the prakriti and vikriti distinction into one static label, treating a system meant to track ongoing seasonal change as a permanent personality profile instead.
