Langhana — literally 'to make light' — is the Ayurvedic practice of lightening or reducing therapy. Its purpose is to rest the digestive fire (agni) and clear accumulated toxins (ama). When agni is overburdened by too much food, the wrong food, or irregular eating, undigested residue (ama) builds up. Fasting is the most direct form of langhana: it gives agni the space to process what remains, and to return to its natural, balanced strength.
Take the to get dosha-specific fasting guidance.
Vata is light, dry, cold and mobile by nature. Fasting aggravates these qualities, so Vata types should fast gently and briefly — never long or strict.
Duration: Maximum 12–16 hours. Skip dinner rather than skipping breakfast.
Style: Warm liquids only — ginger tea, warm water with a squeeze of lemon, or light vegetable broth. Avoid dry or cold fasts entirely.
Pitta is hot, sharp and intense. Fasting cools and pacifies Pitta, but skipping meals entirely can provoke irritability and a burning, reactive quality in the digestion.
Duration: Up to 24 hours. A 24-hour reset once a week is well tolerated.
Style: Lukewarm water, herbal teas (coriander, fennel, mint), or coconut water. Avoid hot, spicy or sour liquids during the fast.
Kapha is heavy, slow, dense and stable. Fasting is the single most effective therapy for Kapha — it lightens, dries and stimulates what is naturally slow.
Duration: Up to 36–48 hours. Kapha tolerates fasting best of all doshas.
Style: Warm water, ginger tea, or light broths. A total water fast or even a dry fast for short periods is appropriate for robust Kapha constitutions.

Breaking the fast matters as much as the fast itself. Agni has been resting and is delicate — the first foods must be warm, light and easy to digest, or the benefits of the fast are lost.
The first thing you consume should be warm, light and easily digested. Never break a fast with a heavy, cold, or raw meal — agni is delicate after resting.
Begin with a cup of warm water, ginger tea, or thin broth. This wakes agni gently before any solid food arrives.
After 15–30 minutes, take a small portion of warm, cooked, easily digested food. Kitchari (rice and mung dal), cooked soft fruit, or a light soup are ideal.
A teaspoon of warm ghee and digestive spices (ginger, cumin, fennel) helps rekindle agni and prevents the sluggishness that can follow a fast.
Do not return to a full, normal meal immediately. Let the first small meal settle for 2–3 hours before eating again.
For the rest of the day, avoid heavy, fried, cold, raw, or processed foods, dairy, and red meat. Your digestion is still rebuilding capacity.
Important: This guidance is educational and rooted in traditional Ayurvedic practice. If you are pregnant, nursing, managing a medical condition, or on medication, consult a qualified healthcare practitioner before fasting. Fasting is not recommended for children, the elderly, or those who are underweight.
