From a box of tea:
Sit cross-legged or in a chair with spine straight and feet flat. Curl your tongue down its length and extend slightly past lips, inhale deeply through tongue and exhale through nose. Continue for 1 to 3 minutes. Finally, inhale, pull tongue in and hold breath briefly, exhale and relax. Feel the cool burst of refreshment.
Before doing this exercise or participating in any exercise program, consult your physician.
Hello, doctor? Is it OK if I breathe?
