[Comparative evaluation of different methods for normalizing heat state of persons exposed to cold water].

Decrease of deep body temperature in humans due to exposure to cold water continues after the exposure ends and carries major danger for human health and life. The article covers data characterizing human heat state parameters after rejection of cold (10 +/- 1 degree C) water environment. This rejection was proved to take place in more severely decreased "core" and "capsule" temperature vs that in air environment. Studies of heat state in 38 volunteers practicing winter swimming demonstrated comparative evaluation of various heating methods among which the most effective are immersion into warm (38 degrees C) water with simultaneous hydromassage and being in sauna at air temperature of 65 +/- 5 degrees C.
