[Changes of functional state of the human body and the dynamics of its recovery in hard physical work in protective devices in various air temperatures].

Effect of the hard manual work on humans using the individual protective means in temperature conditions from 17 to 30 degrees C was studied. The investigation revealed the altered thermoregulatory, circulatory, central nervous systems and the acid-base status. The changes were found depending on the environmental temperature. The recovery period (one-hour rest and shower) did not normalize the disordered functions, so further correction of the functional status is necessary.
