Human heat stress refers to the physiological and psychological stress caused by heat accumulation when the human body is exposed to high temperature. This stress state may cause a series of health problems, such as heat stroke, dehydration, heat exhaustion, etc. The degree of heat stress in the human body depends on many factors, including ambient temperature, humidity, wind speed, solar radiation intensity, as well as the individual's physiological state and adaptability. Urban areas are usually warmer than suburban and rural areas due to the "heat island effect", which increases the risk of heat stress. In the field of urban planning, the response strategies mainly include optimization of building spatial morphology, construction of green infrastructure, smart city technology, etc.
