Vatas are people with a constitutional predisposition toward dryness, coldness or lightheadedness due to an excessive movement in their system which causes them to feel ungrounded or spacey when they experience these qualities. They tend towards being airy and spontaneous but not necessarily flighty; it is difficult for vatas to focus on one thing at a time because of the constant motion within themselves, so they may have trouble staying still in their bodies even if they are physically active or moving around.
