Coronavirus: Doctor demonstrates breathing technique

A British NHS doctor has developed a breathing technique that he says can help coronavirus patients.
Renowned author JK Rowling also claimed Dr Sarfaraz Munshi’s technique, which he devised while helping his mother, helped her when she was suffering from coronavirus symptoms.
Dr Munshi has warned, “The point here ... was that it’s not formal advice, but it’s a simple breathing technique that you can use that can help to oxygenate the lungs and open up the small airways."
