My other favorite "Bhati"
Kapalbhati (kapal meaning skull and bhati means shining) pranayama is the go-to for allergy and sneezing relief. It can help clear the respiratory passage and keep it free from impurities and excess mucus. It purifies the frontal air sinuses and stimulates the brain.
My other favorite "Bhati" is Jaspal whose TV shows used to be a laughter riot back home. Laughter strengthens your immune system, boosts mood, diminishes pain, and protects you from the damaging effects of stress.
