While in India, I have had amazing ayurvedic treatments based on my dosha. As mentioned in an earlier posting- there are 3 constitutions or doshas vata, pitta and kapha, although we rarely are a single dosha.
My prakruti is vata – pitta, that is air and fire, which lends to treatments that use oils that are warmed and bring heat to the body, and steam saunas to bring moisture.
The cool and dry temperatures in Japan at present easily aggravate the vata elements, especially having been in humid 37*degree weather. It is so fascinating how this ancient science for living well so accurately describes our preferences and nature.
While identifying your constitution is best done by an Ayurvedic doctor, there are online questionnaires that do are pretty accurate. To find out yours visit www.whatsyourdosha.com/quiz or http://store.chopra.com/dosha-survey.asp
