Led by Prof. Albert Chan of PolyU’s Department of Building and Real Estate and joined by experts from the Hong Kong Institute of Education and the Technological and Higher Education Institute of Hong Kong, an interdisciplinary study has shed light on the prevention of heat stroke for outdoor workers in a scientific manner.

Based on 411 sets of meteorological and physiological data collected over 19 hot and humid days in last summer, the research team has developed a sophisticated model to compute the optimal recovery time for steelworkers who work in a hot and humid environment at construction sites. In the next stage, the researchers will further develop anti-heat stress clothing for workers.
