Jwara is a Sanskrit word for fever and according to Ayurveda it is considered the "king of all illnesses". This is because Jwara affects not just the body but also the mind and senses. Ayurveda understands jwara as not only an increase in body temperature but is also a feeling of malaise, unease, and discomfort, and involves the deha (body), indriya (senses), and mana (mind).
