Abstract
In order to examine the thermal environment of elderly people during daily life in summer, we measured the air temperature and humidity indoors and outdoors where elderly and young people stayed, their individual microclimates inside clothing and daily activities for three days in August. The elderly people lived in rooms with higher air temperatures and humidity in comparison to young people due to the shorter utilization time of air conditioning and higher temperature settings during use. Therefore, in an effort to prevent heat disorders among elderly people indoors, we recommend that thermometers be placed prominently indoors, the elderly instructed to rely on thermometer readings more than on their thermal sensations, and that air conditioning be used sufficiently to maintain the appropriate room temperature.
