The adverse health effects of home low-humidity conditions

Part5 Analysis of relationship between perception of dryness and exposure environment under thermally neutral conditions and non-thermally conditions

Abstract

In recent years, as houses have become more highly insulated and airtight, low humidity environment is more likely to occur in living spaces during the winter, which has led to a number of dryness problems, such as dryness of body parts and static electricity. On the other hand, the psychological response “perception of dryness” has also been identified as one of the problems of dryness in winter, but little is known and it is not clear whether “perception of dryness” has an impact on health. It has also been shown that when evaluating the “perception of dryness” in housing, it is necessary to pay attention to the thermal environment to which one is exposed. Therefore, in this study, houses where physical data were obtained in a measured survey were used for analysis to examine the relationship between subjective evaluations such as “perception of dryness” and “acceptance of perception of dryness” under thermally neutral conditions and non-thermally neutral conditions indoor and the exposure environment such as indoor temperature and humidity and formaldehyde and acetaldehyde concentrations.
