In plain English

Three forces govern every function in your body. Vata moves things — nerve signals, breathing, digestion's movement, thought. Pitta transforms things — food into energy, sunlight into vitamin D, information into understanding. Kapha gives things structure — bones, muscles, the fluid in your joints. When all three are balanced, you are healthy. When one is too strong or too weak, disease forms.

Each Dosha explained

Vata is Air and Space. It governs all movement in the body — nerve impulses, breathing, the movement of food through the gut, and thought itself. In balance: creative, energetic, quick. Out of balance: anxious, scattered, dry, constipated, cold, insomniac.

Air (Vayu) + Space (Akasha)

Colon, pelvis, bones, skin, ears

Movement, breathing, nerve signals, speech, elimination

Anxiety, insomnia, constipation, dry skin, joint cracking, irregular digestion

Cold, irregular meals, travel, stress, dry food, overexertion

Warm oily food, regular schedule, warmth, sesame oil massage

Pitta is Fire and Water. It governs all transformation — food into tissue, sunlight into warmth, experience into understanding. In balance: sharp, decisive, warm, well-digested. Out of balance: irritable, inflamed, burning, angry, overheated, hyperacidic.

Fire (Agni) + Water (Jala)

Small intestine, liver, spleen, eyes, blood, skin

Digestion, metabolism, vision, skin colour, intelligence, temperature

Inflammation, acidity, rashes, anger, burning, loose stools, irritability

Hot spicy food, alcohol, sour-fermented food, sun exposure, competitive pressure

Cool sweet food, bitter tastes, avoiding heat, moderate exercise

Kapha is Earth and Water. It governs all structure — bones, muscles, the fluid that lubricates joints, the mucus that protects the respiratory tract. In balance: strong, stable, calm, patient. Out of balance: heavy, congested, slow, lethargic, tendency to weight gain.

Earth (Prithvi) + Water (Jala)

Stomach, lungs, throat, head, joints, plasma

Lubrication, structure, immunity, stability, memory

Weight gain, congestion, lethargy, oversleeping, attachment, slow digestion

Heavy oily food, daytime sleeping, cold damp weather, lack of movement

Light warm food, exercise, dry heat, stimulating herbs like Trikatu

Why the same symptom needs different treatments

This is the core of Ayurvedic personalisation — and the reason it cannot be simplified to herb lists.

💩
Same symptom, different Dosha
Two people both have constipation. Vataja: dry, hard, infrequent — needs warm oil and warmth. Kaphaja: heavy, sluggish, mucus — needs light food and movement. Treating both identically helps one and harms the other.
🔥
Like increases like
Every substance has qualities. Hot food increases Pitta (heat). Cold increases Vata and Kapha. Heavy food increases Kapha. Treatment works by applying the opposite quality — this is why knowing your Dosha makes dietary advice meaningful.

Prakriti vs Vikriti
You were born with a specific Dosha mix (Prakriti — your constitution). Your current Dosha may be different (Vikriti — the current imbalance). The Prakriti quiz establishes your baseline. Treatment targets the Vikriti.
Charaka Samhita, Sutrasthana 9.4

Vata pitta kaphascha — Vata, Pitta, and Kapha in their natural balanced state are the supports of the body. In their disturbed state, they are the causes of disease.
