Sinus Infections

Before beginning Bikram yoga, I had chronic sinus problems. The year before I started, I was on antibiotics almost continually for six months trying to get rid of  sinus and ear infections. I have not been on antibiotics except twice in the last 6 years - once because of
a cat's bite. I still struggle with sinus discomfort because of the dryness, pollution of the denver area but I believe yoga has boosted my immune system sufficiently to deal with this chronic condition.
