Protective Facemask Impact on Human Thermoregulation: An Overview

Description:

Protective facemasks (PFMs) negatively impacts respiratory and dermal thermoregulation mechanisms of human thermoregulation. This research found relatively minor  increases in core temperature directly attributable to wearing PFMs. which suggests that 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.

Guide on respiratory protection against bioaerosols: Recommendations on its selection and use

Description:

The recommendations stated in this document apply to all people in charge of workers’ respiratory protection against bioaerosols, whether infectious or not. All the recommendations specifically relate to respiratory protection against bioaerosols. For other types of exposure (direct or indirect contact with the body), other means of protection must be considered : wearing sealed  goggles or visor, gloves and coveralls, hand washing, vaccination, etc.
