Abstract
This study aims to understand the potential impact of partial sleep deprivation on the relationship between the overall thermal sensation, the local body skin temperatures, and the indoor thermal environment. A series of human experiments with 46 participants were conducted in an experimental chamber. Eight local body skin temperatures (stomach, back, chest, neck, forehead, arm, wrist-in, and wrist-back) and overall thermal sensation were measured under six temperature conditions. The result revealed a significant difference in the overall thermal sensation between the two sleep groups under three indoor temperature conditions (20°C, 26°C, and 28°C). Among the local body skin temperatures, the wrist-in and wrist-back showed a relatively strong correlation with the overall thermal sensation in both sleep groups. The correlation between the wrist-in skin temperature and the overall thermal sensation was stronger in the partial sleep-deprived (PSD) group while the correlation between the wrist-back and the overall thermal sensation was stronger in the normal sleep (NS) group. In conclusion, this study showed that people with partial sleep deprivation are less sensitive to the thermal environment compared to people with normal sleep. The findings of this study demonstrated which local body skin temperature can be used to estimate the overall thermal sensation effectively for partially sleep-deprived occupants. These findings provide various occupant conditions for indoor thermal environment control, expanding the understanding of the occupant’s optimum thermal comfort.
