Yoga-based asthma cure.

the yoga routine called alternate nostril breathing (anb) is a good starting point for a sprayless asthma cure as used in Russia.

In anb the nostrils a pushed from side to side to close them in turn. Such finger pressure acts by reflex to dilate the lung airways like a spray.

A sharp loud sniff has the same nose-pressing reflex effect. See demo "Strelnikova to reduce asthma" Tweet
