Description
<p>In order to clarify the heat stress effects, under ambient air temperature and humidity, on thermoregulation, psychological responses, autonomic nervous and salivary amylase activity of the human body, 6 young female subjects wearing only shorts and a brassiere were exposed to 9 conditions consisting of air temperature of 28℃, 31℃ and 34℃ and 30%, 60% and 90% relative humidity for 60 minutes. The results of the analysis of variance are summarized as follows: ①Mean skin temperature, sweat rate, skin moisture were significantly increased with an increase in air temperature and humidity, but rectal temperature showed no significant differences. ②Thermal, humid and uncomfortable sensations changed to the uncomfortable side with increasing temperature and humidity. ③Heart rate, LF (Low Frequency)/HF (High Frequency) and salivary amylase activity were significantly increased with an increase in air temperature and humidity, while HF showed only tendency to be decreased. ④High correlation coefficients between skin moisture and uncomfortable sensations (r=0.888), humid sensations (r=0.982), salivary amylase activity (r=0958) and LF/HF (r=0.910), suggested a dominant indicators of the heat stress. Salivary amylase activity and LF/HF were also suggested as an effective indicator of heat stress.</p>
