[The physiological mechanisms of the adaptation of metal workers to exposure to elevated convection and combined radiant and convection heat].

Metallurgists exposed to exceeding amounts of radiant heat and convection heat combined with the radiant one demonstrate such general physiologic adaptational mechanisms as: reflectory tachycardia, intensive sweating, heat conducting to the skin surface of the body, abruptly increased minute respiratory volume and possible filtrative sweating. Furthermore heavy physical work induced the extremely abrupt tachycardia, the increased systolic and pulse pressure, systolic and cardiac output, total ventilation per minute. The recommendations were suggested to prevent overheating in workers.
