Extreme Heat

Heat kills by dehydration and by overwhelming the body's ability to shed heat, and both show up as Exhaustion before anything worse happens. Armor makes it worse, and the better the armor seals, the worse it gets. Deserts, forge halls, vent fields and reactor spaces can all produce it.
