The ammonia smell comes from your sweat. Sweat, in basic terms is slightly diluted urine and contains NH3 (ammonia). In my experience, the smell from sweat is stronger when I'm dehydrated which is logical as the concentration of ammonia in my urine and sweat will be higher. I use it as a sign that I need to drink more.
