[Thermoregulation changes in secondary vocational and technical school students during the summer job experience]

Ninety pupils from a secondary polytechnical school for non-ferrous metallurgy, studying locksmith-mounter specialty, were examined during their summer industrial practice. The changes in body temperature, skin temperature and skin-electric resistance (SER) were studied. It was found that the diurnal and weekly variations in body and skin temperature and SER follow the diurnal and weekly biorhythm of these parameters and directly reflect the environment temperature changes and the duration and intensity of the work performed.
