Chronic sinus congestion affects 31 million people in the United States, making it a highly prevalent condition. Acute sinusitis, occurring for less than 4 weeks, is even more common, affecting 50 million adults every year.
In Ayurveda, both vata and kapha dosha cause colds and flu when they are out of balance and immunity is weak. Excess kapha dosha has the qualities of cool, heavy, and moist which causes runny nose, sneezing and a cough with a lot of phlegm. Excess vata dosha has the qualities of dryness, lightness and moving fast which causes coldness with chills and a dry cough.
