SmartWatch for Predicting Human Condition Under Extreme Environmental Conditions

Introduction. Global warming, population growth, and urbanization—with increasing building density — create high risk conditions for humans. Even those adapted to climate change may be unprepared for sudden heat waves, which have adverse health effects. Currently, there are several smartwatch applications available that assess human thermal comfort in various environmental conditions. However, there is a lack of technology that can provide early warnings about the dangers of hot environments. The purpose of the paper is to develop a smartwatch application designed to assess the condition of individuals in hot environmental conditions. Results. A smartwatch application has been developed to predict human thermal status in hot environmental conditions. The application takes into account environmental conditions, clothing, and physical activity levels. Conclusions. The smartwatch integrates mathematical models of human thermoregulation with modern mobile technologies. This allows for predicting a person's thermophysiological state in extreme environmental conditions. The developed approach enables the prevention of health damage under various environmental conditions and levels of physical activity.
