A dosha is one of three bodily humors that make up one's constitution according to Ayurveda. These teachings are also known as the Tridosha theory. The doshas come from the five states of matter: ether (space), earth, water, air and fire.
Vata dosha ether and air: The most powerful of the doshas, controls basic bodily functions as well as the mind.
Pitta dosha fire and water: Controls metabolism, digestion and hormones linked to appetite.
Kapha dosha earth and water: Controls strength and stability, muscle growth, weight and the immune system.
