摘要:Hot and cold thermal environments interfere with the body's thermoregulatory system, which reacts to ensure thermal balance.The response to changes at room temperature occurs through a process of physiological adjustment to the new environmental conditions.This process plays a key role in human health risks prevention.This article aims to present some of the MeFinSA (Mental Fatigue in Sedentary Activity) project results related to changes in skin temperature, in a process of acclimation to different temperatures at the same relative humidity, in a sedentary activity.For this purpose, tests were performed in a climatic chamber with eight male volunteers.The tests lasted one hour a day and were repeated by each volunteer during eight days, for each of two temperature conditions (20ºC and 32ºC) with a relative humidity of 60%.It has been found that there is a greater homogeneity in the temperature of the skin in warmer environments (32°C) when compared with colder environments (20°C).These results are consistent with those obtained by other researchers.
