Vata dosha governs all movement in the physiology, from the subtle, fleeting movement of a thought flitting across your mind to the coursing of blood through your arteries and veins. Air and space in combination forms vata dosha.
The five subtype of Vata:
Prana Vata is the central co-coordinator of all the vata and functions in the head-neck-chest region. Thinking, creativity, learning new information and inhalation are examples of Prana Vata governed activities.
Udana Vata functions in the throat and chest region. Sneezing, singing and exhalation are examples of Udana Vata regulated activities.
Vyana Vata radiates from the heart to all over the body through the circulatory system and the skin. The beating of the heart, sweating and the sense of touch are examples of Vyana Vata activity.
Samana Vata works in the stomach area, governing the flow of food through the digestive tract.
Apana Vata works in the colon and pelvic area and governs such functions as menstruation and the expulsion of urine, semen and stool.
