We came across this very informative article on Knowing How Heat and Humidity Affect Your Body Can Help You Stay Safe During Heat Waves. It does a good job of explaining the unusually high deaths from heat illness recently in Oregon, Washington, and British Columbia, Canada.

While here in the Eastern Sierra, especially in the Owens Valley and Death Valley, humidity is typically low and allows for our bodies to sweat, cooling our bodies through evaporation, and that’s well and good. But we do not always stay here and often travel to places which now have issues with excessive heat and humidity. And then there is the simple fact that heat can kill whether the humidity is high or low.

What we like about this particular article is that it explains the physiology of excessive heat on the body and gives concrete information on how to avoid it.
