Preliminary investigation on the effectiveness of fan-attached jackets in improving dynamic thermal comfort

It is necessary to consider various adaptation methods in the context of global climate change and urbanization, which are causing health and social risks. This study investigated the effectiveness of using fan-attached jackets as a thermal comfort adaptation measure for daily situations with consideration of the dynamic physical and psychological responses of the human body to the thermal environment in Japan. By doing an outdoor experiment with wearable observation devices, we identiBied the potential effectiveness of fan-attached jackets such as the reduction of discomforts while walking during summer and acceleration of recovery to a comfortable state afterward. The Bindings suggest that fan-attached jackets can alleviate both physiological and psychological thermal stress in warm conditions, making them suitable as a heat adaptation measure for daily use.
