Definition - What does Humming Breath mean?
Humming breath is the action of making a light humming sound while practicing pranayama, or yogic breathing.
To practice humming breath, begin in a comfortable seated position such as lotus pose. In a four or six count breathing pattern, make a humming sound similar to the buzz of a bee during the exhale of the breath. Once the sound on the exhale is mastered, a sound can also be attempted during the inhale.
Humming breath may also be referred to its Sanskrit name, bhramari pranayama.
Yogapedia explains Humming Breath
Humming breath is considered to be beneficial for thyroid and sinus problems due to the affect of the sound vibrations. Many yogis also consider this breathing technique to alleviate stress, anger, tension in the mind, insomnia and anxiety. The believed benefits of humming breath stem from the concept that the soothing buzzing sound is beneficial for both body and mind.
Yogis may choose to practice this breathing technique with a mudra, or with a finger in each ear and remaining fingers over the eyes in order to reduce other auditory or visual stimulation and fully take in the relaxing effects of the sound.
