What causes the wind to move?
The Vata life-force, made up of ether and air.
Vata causes all movement within the body too, such as peristalsis, defecation, urination, respiration, ejaculation, sneezing, coughing etc.
If you are a Vata type, you'll tend to be mobile, perhaps waving your hands when talking, or perhaps raising just one eyebrow. You'll be hugely creative, cerebral, probably spiritual.
And when you go out of balance, you'll feel cold, dry, resulting in constipation, creaking joints, insomnia, lack of concentration, memory loss, fear and anxiety. And feel a constant need for change.
That's when you compensate by adding more heat to your diet in the form of spices, warm food, as well as more unctuousness.
