Langhana
The lightening strategy of Ayurveda: everything that makes you lighter — smaller meals, mono-diets, gentle fasting, movement — to digest and clear the system.
Langhana comes from laghu, "light": it is the whole set of measures that lighten body and mind. With its opposite, brimhana (what nourishes and builds), it forms the fundamental alternative at the heart of all Ayurvedic therapeutics: faced with an imbalance, you either lighten or nourish. Excess, heaviness, congestion and ama call for langhana; exhaustion, thinness and dryness call for brimhana.
Langhana is not just fasting. The tradition includes a graduated palette: reducing portions, eating dinner early and light, skipping a meal when appetite is absent, spending a few days on a mono-diet, drinking warm liquids, moving more, all the way up to the supervised purifications of panchakarma. Ayurveda almost always prefers the gentle version: a two- or three-day kitchari mono-diet rather than a strict fast, which is considered too aggravating for Vata.
A concrete example: after an over-rich holiday season — coated tongue, heaviness on waking, no appetite — a few days of simple, warm, smaller meals with hot water through the day amount to a complete langhana. Kapha, the naturally dense and stable dosha, is the one that benefits from it most regularly, especially in spring. For the practical side, see our article on fasting and Ayurveda: sobriety rather than deprivation and our approach to Ayurvedic detox without extremes. If you have a history of disordered eating, are pregnant or live with a chronic condition, discuss any lightening protocol with a doctor first.
