Ayurveda refers to any type of coughing as Kasa and is a respiratory system disorder that occurs due to the obstruction of vata dosha. Prana vata is located in the respiratory system, and when it becomes obstructed the natural downward flow reverses forcefully upward causing the urge to cough. This is what Ayurveda refers to as Kasa.
Prana is the vital life force that energizes what is essential for all life. Prana vata is the inward movement of life force energy coming into our bodies. It’s the inhalation of oxygen, the digestion and assimilation of nutrients, and the perception of sensory input that connects our senses, mind, and body. Prana is directly responsible for life itself as it nourishes the vitality of all our cells.
