At Yoga Synergy (Bondi), I learned a basic prāṇāyāma technique called Śitali (Tongue Hissing), a cooling and detoxifying breath to curb fever, anxiety, and control appetite. This is in contrast to the Ujjayi Prāṇāyām (Victorious or Cobra Breath), an ocean breath that builds internal heat.
In Śitali Prāṇāyām, air is inhaled through the protruding tongue that is curled into a tube. As air passes over the moist tongue during inhalation, it cools and refreshes the throat.
Other yogic breathing techniques include Bhramari Prāṇāyām (Humming Black Bee Breath) and Śitkari Prāṇāyām (Teeth Hissing Breath).
