Swedana, one of the Shadvidhopakrama, constitutes an essential Poorvakarma in Panchakarma procedures. It effectively alleviates Shoola (pain), Stambha (stiffness), Gaurava (heaviness), and Shaitya (coldness) while promoting sweating and inducing softness in the body. Swedana is classified into two types: Sagni (fire-based) and Niragni (non-fire-based). Niragni Swedana stimulates perspiration without external heat through methods such as Vyayama (exercise), Ushnasadana (warm chambers), Gurupravarana (heavy coverings), Kshudha (fasting), Bhaya (fear), and Krodha (anger). These techniques promote sweating by metabolic, emotional, or thermal triggers, helping to remove Ama, relieve Stambha (stiffness), and Gaurava (heaviness), and restore Srotas (microchannels).s Niragni Swedana is ideal for treating conditions like Prameha, Sthaulya, and Urustambha, which involve excess Meda and Kapha and where Sagni Sweda is contraindicated. It aligns with Ayurvedic detoxification therapies such as Langhana and Apatarpana, enhancing Agni Deepana. From a modern perspective, its effects resemble controlled thermogenesis, sympathetic nervous system activation, and enhanced circulation seen in aerobic exercise and fasting. This therapy is safe, cost-effective, and adaptable for use across all ages for both preventive and therapeutic Ayurvedic care.
