Exactly so, but it did not sound to me like that is what he was talking about. He was going on about staying moist. If the surface of the body dries out, it is because all the moisture on the surface has evaporated, for cooling purposes the best possible case, i.e. most evaporation means most cooling. He suggested that staying wet on the surface helped to keep one from dehyrdrating. The actual effect would be just the opposite. I wonder if he meant that enough evaporative cooling wasn't the problem, but rather too much evaporation was the problem.
