Vata is the "king of doshas" and controls all the movement, communication, and transportation in the body. This mean that vata is found in the nervous system, circulatory system, bladder, kidneys, breath, movement of arms and legs, and elimination portion of the digestive system.
Signs of a balanced vata are showing enthusiasm, alertness, sleeping well, being flexible (both mentally and physically,) and overall good physical movement throughout the body.
