https://en.m.wikipedia.org/wiki/Wet-bulb_temperature


Wet bulb, dry bulb comfort measurement.

Wrap the wet bulb thermometer with cheesecloth.

Blow a fan across the bulb.

This is the lowest temperature that evaporative cooling can achieve at that point in time. A very useful tool.

Only way I survived summers at Ft. Irwin was to keep my uniform wet. Didn’t know the science...did know the relief.

One way. in fact the most accurate way. to measure humidity requires a dual bulb (one wet one dry) thermometer a piece of string and a book.

You start by slinging the thing around for a bit.
Read both thermometers and note the temps
Look the dry temp up in the book then the wet and where the two cross

HUMIDITY.


Home was where I park it. but alas the.

Just get a sling psychrometer, (Amazon} I used them at work to determine the wet bulb temp. That's what the 'Feels Like' temp comes from. It's done electronically now, my indoor-outdoor thermometer does it with no slinging. This old tech....heh.

No batteries no transistors no drift no plus minus percentage errors. And twelve dollars.

If you are properly hydrated, in low humidity, you can think of yourself as as cool, wet bulb guy. In high humidity, . . . your're just another sweaty (maybe stinky) guy.

I found through the school of hard knocks that in dangerously high temperatures that a pure ice slurpee made in a blender can ward off really awful effects. I Make sure I have enough salt in my system then grind ice and stick it in a thermos. I have lowered my body temperature 2+ degrees by eating the ice. I start off slowly but consume a pint or so of shlilusy ice. Too much, too soon may be hard on the body. Alcohol, caffeine or sugar seems to kick my butt. I don't drink but watching other people, beer and booze are both bad for health in broiling temperatures.
