What is “wet bulb temperature” and why does it matter?
In: 3256
Ah… the good ol’ WBGT…. Think of most temperatures as a piece of data without context…. Having a car with a lot of horsepower doesn’t do much good if the engine will destroy the rest of the car, right? Ok, we’ll, a wet bulb temperature is supposed to help simulate “perceived” temperature to the body.. your body does an amazing job cooling itself and you don’t notice but shade, humidity, etc make a lot of cooling harder for your body… the wet bulb simulates a “sweating” person cooling off (so a dry 113 in West Texas may still suck, but it’s a lot easier for your body (with breaks and hydration) than 95 with 100% humidity in Ohio… the primary purpose is to regulate work rest cycles for people doing harder work outside. I could go on for hours about the details but I think that basically covers it.
