Investigation of key thermoregulation parameters in relation to the thermal state of auto repair workshop workers during the warm season

Abstract

This study investigates the main indicators of thermoregulation in relation to the thermal state of auto repair shop workers during the warm season. The research was conducted to assess the effect of elevated air temperatures and unfavorable microclimatic conditions on the body’s thermoregulatory mechanisms. Skin temperature was measured at five body surface points (forehead, chest, hand, shin, and foot) using a TPEM-1 medical electric thermometer, while body temperature was recorded in the axillary region. The results revealed a significant increase in both body and skin temperatures during the working day, particularly in the distal areas of the limbs. A reduction in the proximal–distal temperature gradients indicated overheating and strain on the body’s thermoregulation systems. Despite the relative stability of core temperature, the observed physiological changes demonstrate a state of thermal stress caused by heat exposure. These findings highlight the importance of optimizing microclimatic conditions in industrial environments to maintain workers’ health and efficiency.
