In the ancient Indian medical system of Ayurveda, when someone is wiped out from too much travel, they call it vata deranged. Vata is the element of air and movement, and when you travel a lot you can become ‘airy,’ unstable, imbalanced. In Energy Medicine Yoga, we learn how the body can become ungrounded and out of synch with the polarity of the earth and the energetic time zones that we entrain to when we live someplace. That is the basis for jet lag. You live in one time zone and when you fly, you’re very quickly shot into another.
