Even more uniquely, we have unmatched opportunities to behaviourally shield ourselves from heat stress, e.g., by reducing clothing, using shelter, and accessing fans and water. Most of our heat stress even on the hottest days comes from inside us — our metabolism — rather than the environment (especially if shaded). Yet, warm and wet skin make us believe it is hot air, sun or high humidity. These realities of heat stress raise several issues. We are the single species that is increasingly and knowingly responsible for rising levels of heat and humidity.
