For better result, Is there any sequence to do the pranayam? I normally do these Om pranayam, Anulom Vilom, Bhamari, Kapalbhati.

Yes, the sequece and timing of Pranayam sequence is very important. 1) Bhastrika 5 minutes. 2) kapal bhati 15 min. 3) Bahaya pranayam 3-5 times, Agni saar 4) Anulom Vilom. 15 min. 5) bhramari 3-5 times. 6) Udgeet 3-5 times 7) Pranav meditation. The timing is doubled if a problem grave. Start practicing in sequence and BE HAPPY !! 15 min. 5)
