People who have mostly vata in their constitutions are generally active, creative, and spontaneous. They might talk quickly and walk at a rapid pace. They have imaginative minds and enjoy experiencing new things, meeting new people, and visiting places they haven't been before. But they also tend to dramatic fluctuations of mood, appetite and energy. They may experience high energy in short bursts, and become easily overstimulated. The vata body is often tall and lanky, or willowy. Often, vata skin is cold and dry. Their hair may be frizzy and/or brittle. When imbalanced and provoked, a person with excess vata will feel anxious and have trouble sleeping.
