Lately I have noticed that my sweat smells like ammonia while I am practicing. Do you know why?

This is nothing to be alarmed about. The ammonia smell could be a sign of kidney failure if it occurred in your sweat and breath all the time but if it's only associated with vigorous exercise it's almost certainly diet related. It's common among marathon runners and usually comes from having a low carb/high protein diet. You may want to include more complex carbohydrates in your diet.

If you have serious concerns about this or any other health issue you should always seek advice from a doctor or other health care professional. Our preparation as Yoga instructors does not include medical training.
