• Resumen

  • In a previous article1 I analyzed in detail the physical factors resulting in greater cooling rates of objects in still water than in still air, emphasizing cooling of the human body. By cooling rate I mean the rate of decrease of core temperature uncompensated by metabolism. I concluded that the �correct ratio for humans is closer to 2 than to 10.� To support this assertion I subsequently did experiments, which I report following a digression on hypothermia.
