Description

<p>  In the present study, to clarify the risk of heat disorder and thermal comfort during moderate exercise while wearing a mask in a hot environment, masks to prevent infection of three different types were compared in a subjective experiment in a climatic chamber. We evaluated the materials' physical properties and the comfort-related performance of each mask. The external ear temperature of each mask was lower than the standard for a serious condition of heat disorder, indicating that each mask does not pose a significant risk of heat disorder. The particle collection efficiency of the pleated nanofiber-nonwoven mask (NF) was above 90%. The mask microclimate temperature and uncomfortable feeling of NF were lower than other masks. For moderate exercise in a hot environment, the NF was found to be the most suitable mask in terms of infection prevention and thermal comfort.</p>
