Bee Breath - Bharamari

Bee Breath or Bharamari is a fun breath that has a calming effect and elongates the exhale.  Bee breath can be used to relieve anxiety, help ADHD, OCD and depression. I also read one website that suggested using Bee Breath for migraines.  In India Bee Breath is often used for woman in labor.  I have noticed when we are practicing Bee Breath in class, and I sit and listen, I feel a sense of calmness come over me and can not refrain from smiling. 
How to:
Sit comfortably in a quiet area, sitting tall, relaxed shoulders, eyes closed of lazily focused on the floor.
Begin to focus on your breath, noticing the inhale and exhale. 
After a few breaths, focus on your exhale.  Begin to "hum" your exhale. 
Tuck your chin slightly.
As you continue to breath, notice where you feel the vibrations created by the humming exhale.
Continue to practice Bee Breath following your comfort.

Enjoy!
