Effect of Environmental Heat Stress on Maternal, Fetal and Infant Health: A Cohort Study

"Heat stress (exposure) will be quantified using validated environmental heat stress indices, including the Universal Thermal Climate Index (UTCI), Wet Bulb Globe Temperature (WBGT) and heat index (HI). The former two indices integrate four key environmental parameters, ambient temperature, relative humidity, solar radiation, and wind speed, to provide a quantified measure of thermal stress. The heat index represents the apparent temperature or how hot it feels to the human body when air temperature is combined with relative humidity.~Indoor heat exposure will be assessed using wearable temperature and humidity loggers, while outdoor environmental data, including temperature, humidity, radiation, and wind speed, will be captured using Kestrel WBGT devices installed in the study area."
