Heart rate responses to industrial heat stress.
J Physiol 1971 Jul-Aug; 63(3):342-345
The effect of heat stress on heart rate was recorded by continuous ECG in helpers in the open hearth department of a steel mill. The results show that physiological strains in men performing hot industrial jobs vary, depending both on the individual's work capacity and on the varying demands of the job, and that a decrement in cardiocirculatory performance capacity after the work shift is a good criterion for the evaluation of excessive work strains. Prevention of health hazards to workers in hot industries from excessive physiological strain requires selection of workers with high heat exercise tolerance, or better engineering control of environmental heat stress.
