“…For better protection against virus transmission, PPE was designed for fluid resistance and impermeability, limiting evaporation and heat exchange with the environment. Therefore, the body has to dissipate heat mainly via sweat evaporation, leading to the risk of overheating and thermal strain [ [26] , [27] , [28] , [29] , [30] ]. PPE-related adverse events (i.e., thermal discomfort, contact dermatitis, and reduced visibility) have been documented previously and are associated with increased levels of heat stress and relative humidity [ 6 , 11 , [31] , [32] , [33] ].…”
