Asthma and Pranayama
A 2014 study by Cramer, Posadzki, Dobos, and Langhorst reviews and meta-analyses the available data on efficacy and safety of yoga in alleviating asthma. Based on their findings, they conclude that “yoga cannot be considered a routine intervention for asthmatic patients at this point. It can be considered an ancillary intervention or an alternative to breathing exercises for asthma patients interested in complementary interventions”.
