Popis:	The purpose of this study was to develop a new environmental stress index (ESI) based on different parameters relating to heat stress. Meteorological measurements were taken in three climatic zones (hot/wet, hot/dry, and extremely hot/dry) for 60 days, and a new stress index based on these databases was developed as follows: ESI=0.63 T a − 0.03RH+0.002SR+0.0054( T a · RH) − 0.073(0.1+SR) −1 , where Ta is the ambient temperature (°C), RH the relative humidity (%), and SR the solar radiation (W·m−1). The correlation coefficients between ESI and wet bulb globe temperature (WBGT) were very high (R2>0.981). Therefore, we conclude that ESI, based on fast response and the more commonly used accurate climatic microsensors (Ta, RH, SR) which can be combined in a small portable device, has the potential to be a practical alternative to the WBGT.
