The Papworth method, developed 40 years ago, has recently been proven to relieve asthma symptoms, depression and anxiety according to an article published in the journal Thorax. The technique includes a sequence of breathing and relaxation exercises developed in the 1960s at the Papworth Hospital in the U.K. Despite its anecdotal success, no research had been conducted on the method until a recent study by Drs. Elizabeth A. Holloway and Robert J. West, from University College London. Have you used this method or another yogic breathing method to control asthma?
