[Human thermoregulatory reaction to exposure to convective and radiant heat].
Weight loss, cardiac rate, axillary temperature, mean heat temperature and heat sensation was examined in four male subjected to the effect of convection and convection-radiation thermal loads in three temperature levels of the black sphere and three levels of infrared radiation of the anterior and posterior surface of the body. The temperature of air in convection loads was equalled that of the vapour thermometer while in convection-radiation loads it was 4-5 degrees C lower. The amount oF moisture losses by vaporization during convection effects was higher than in convection-radiation effects. But the influence of these differences did not exceed the effect of biological variability. Thermoregulation values were in direct proportion to the sphere temperature that may be considered an integral index of convection and radiation loads.
