Abstract

Preventative measures against heat shock during winter are an urgent problem for the elderly. Heat shock may result in accidental death due to extreme temperature differences within indoor thermal environments. The most common cause of death was from cardiovascular disease or cerebral hemorrhage in the bathroom or restroom. The purpose of this study was to consider prevention against heat shock from the viewpoint of residents. Methods: 1. We surveyed temperature cognition in the restroom and the dressing room. 2. We measured temperature and relative humidity values associated with the restroom during the early mornings, and the dressing room during the nighttime. 3. We surveyed the validity of the effect of the simple thermal insulation on room temperatures. The results were as follows: 1. The temperature cognition survey indicated that residents over 65 years of age were not as sensitive to temperature levels, compared with younger subjects. This was due to the relatively low thermal response of the elderly subjects, compared with the younger subjects, and they stayed in the dressing room for a shorter time period. 2. The measured temperatures were lower than 17°C and temperatures of less than 10°C were experienced more often by the subjects older than 65 years. 3. The simple thermal insulation brought about slight improvements in indoor thermal environments and the thermal comfort of the residents. The installation of the simple thermal insulation induced the residents to spontaneously improve and reform their windows. Our results indicated that recognition of the correct room temperature using thermometers and the simple thermal insulation are valid measures against heat shock from the viewpoint of the residents. It is important to inform residents with concrete information, related to the validity and the cost-effectiveness of preventative measures against heat shock.
