As we began warming up through variations of Sun Salutations, she proceeded to sneeze, cough, and blow her nose throughout the 90 minutes. I realized she wasn't sad; she was sick. I'm sure in her mind she thought that "sweating it out" would help her illness pass through faster, but I kept catching glares from the other students in the class every time she reached for a tissue. I tried to think positive thoughts, since cursing her in my mind wouldn't be very yogic of me, but I too was really upset with her. The room was small, the doors and windows were closed, and all I could think about was, "I'm gonna end up with her cold."
If you only have a sniffle and runny nose and no fever, it's safe to exercise, but you need to be considerate of other people. A good sweat session on the mat may be just the thing to cure your ills, just stick to practicing at home instead of heading to the studio.
