1. Stand or sit straight. Most Photographs show a bent back with towel on head to take steam. That steam is for facial , not your lungs. Stand straight , lungs not bent , airways not squeezed. Adjust the steamers height so.
2. Adjust your nostril and mouth perpendicular to plane of steam. Keep a comfortable distance. Warm enough not to burn.
3. For 1st 10 breaths , just breath in and out at normal pace...no hufpuf. Let airway temperature get adjusted.
4. Next 5 breaths, inhale through mouth , deep but smoothly , to maximum capacity. Feel it going to last of your air passage , down to lower lung lobes. Hold breath for count of 3. Exhale through nostrils smoothly.(no jerks).
5. Next 10 cycles through nostrils. Either _aalom vilom_ i.e. close one nostril and inhale through other...smoothly,slowly. Hold till count of 3 and exhale through the other nostril while now closing the one with which u inhaled. OR , simply inhale exhale through one nostril 5 times each while keeping other closed.
6. Now repeat the mouth inhalation cycle.
7. Take steam this way for atleast 10 min.
8. Keep fan /AC closed during ,and 15 min post procedure.
9. Lie down prone if possible after steam.
10. Last but not the least. Keep a hanky. Whatever secretions liquify in airway due to steam, don't swallow. Try to spit out or take in hanky. Take care
