Abstract

The effect of moderate altitude on human thermal regulation and heat loss may influence human thermal sensation and comfort. This paper aims to clarify this effect and its impact on thermal sensation. Experiments were conducted in a decompression chamber where the air parameters were controllable. Barometric conditions of 1atm and 0.75atm were compared. Sixteen subjects participated in two kinds of activities: sitting and treading in situ. Their metabolic rate, skin temperature and clothing surface temperature were tested. The subjects' thermal sensation votes were collected at each condition. The results showed that physiological parameters of metabolic rate, respiratory quotient and local skin temperatures in both activities were affected by moderate altitude exposure. The total heat loss of human body was calculated and it increased in hypobaric hypoxia environment. The combined effect of enhanced heat loss and decreased local skin temperature caused the change of thermal sensation.
