The other day, I wrote a post on heat-related illnesses, from muscle cramping to the very serious heat stroke (Heat Waves – What’s the Big Deal? ). Today I found an article from a blog in Iowa that does a great job of describing how heat temperatures (including humidity) are calculated and why it feels hotter sometimes than others, even if the temperature is the same: Heat Index – Why It Feels So Hot.

Knowing how and why something works often makes it easier for us to help ourselves, because then we understand why certain things work better than others.
