... 5.1.1 Circulation Most of the current studies of hypothermia, stimulated by interest in its applicability to specialized surgical procedures, are directed toward elaboration of the effects of considerably reduced body temperatures. Work in the area of prolonged exposure to low-water temperatures with moderate depression of body temperature, such as may be encountered in underwater swimming, is receiving very little attention.

From page 24...
... In the actively swimming individual the metabolic heat production is high and, if dissipation of this heat is impeded, considerable discomfort and physiologic derangement can result. Heat dissipation is considerably abetted by the high conductivity of water but if the water temperature is near or above skin temperature, this physical factor is no longer an aid to the swimmer and body temperature must rise.
