Protective facemask impact on human thermoregulation: an overview

Ann Occup Hyg. 2012 Jan;56(1):102-12. doi: 10.1093/annhyg/mer069. Epub 2011 Sep 13.


The use of protective facemasks (PFMs) negatively impacts respiratory and dermal mechanisms of human thermoregulation through impairment of convection, evaporation, and radiation processes. The relatively minor reported increases in core temperature directly attributable to the wearing of PFMs suggest that associated perceptions of increased body temperature may have a significant psychological component or that regional or global brain temperature changes are involved. Modifications in PFM structure, components, and materials might allow for improved heat dissipation and enhanced compliance with use.
