What effect does PPE have on evaporative cooling?

Explanation:
Evaporative cooling depends on sweat evaporating from the skin to carry heat away. When PPE is worn, the protective layers trap sweat and humidity against the skin and limit the evaporation process. This barrier reduces the amount of heat loss through evaporation, so the body can’t cool as effectively. Even as activity level changes and more sweat is produced, the gear still hinders evaporation, so the overall effect is a prevention of evaporative cooling.
