Vocal Health in extreme weather

Here in Southern California, we are in fire season, with exceptionally hot and dry weather. No wait, today it’s cold and damp. And tomorrow it will be dry and extremely windy and cold. It’s like being transplanted from climate to climate, without a scenary change. Everywhere I go during fire season, I hear sniffles, sneezes, wheezes, coughs, and rough, irritated, hoarse, voices, and in some cases extreme laryngitis.
