Different types of personalities or constitutions ("prakrutis") were identified according to the predominant dosha; each prakruti predisposed a person to certain illnesses. For example, vata characteristics included a variable appetite, creative mind, poor to average memory, indecisiveness, rapid speech, erratic spending, nervousness, shyness, and a tendency to experience anxiety and depression. Mental health problems associated with a vata constitution were anxiety, tension, and psychosomatic illness, all of which could be prevented by eating foods rich in pitta and kapha and low in vata, eating moderately sweet and warm foods, avoiding cold foods, and receiving massages with vata oils.
