The purpose of this study was to investigate the safety of applying a hot compress (Maruyama-method) to the lumbar region of elderly based on changes in skin temperature and skin barrier function, and explore factors affecting safety. This study applied a quasi-experiment study design, wherein a hot compress was applied on the lumbar region of 20 elderly people for 20 minutes. No adverse events such as moderate temperature burns were observed, and the deep skin temperature fluctuated below 38℃. The deep skin temperature during and after the application of the hot compresses was significantly higher in the group aged 75 years and over, than in the group aged less than 75 years, suggesting that those aged over 75 years old are more prone to an increase in deep skin temperature and heat accumulation. In terms of skin barrier function, the stratum corneum hydration was significantly decreased before and after the application of the hot compress. These results suggest a low risk of moderate temperature burns among the elderly on application of a hot compress using the Maruyama method. For those over 75 years of age, hot compresses tend to increase the deep skin temperature and heat accumulation; hence, care should be taken when applying hot compresses using other methods. As a whole, the dry heat stimulation induced by the hot compress appeared to reduce the stratum corneum hydration; thus, it is suggested that moisturizing care be provided after implementation of the hot compress.
