title: Reduced tolerance for heat stress environments caused by protective lotions.
abstract: There have been complaints of excessive heat after applying skin protective lotions. The purpose of this study was to determine if oil-base or alcohol-base protective lotions interfere with the body's cooling mechanisms during moderate work in heat stress conditions, and if so, then to identify the mechanisms. This was accomplished by evaluating the effect of lotions on thermoregulation as measured by rectal temperatures, local sweat rates, and total water losses during exercise at elevated temperatures. In comparison to the control, after about thirty minutes, the skin lotion tests resulted in a more hyperthermic condition, as measured by rectal temperatures.
