This breathing exercise acts like a natural tranquilizer for your body and mind. It's beneficial for anxiety, feeling triggered, needing to calm down, or even to get to sleep.This practice gains in power with repetition and practice. You can do it once or twice a day. Start with four breaths at one time for the first few weeks. After a few weeks you can extend it to six or eight breaths. Feeling a little lightheaded the first few times you do this practice is normal and should pass.
