My car thermometer says 91 F / 33 C and I’m running the A/C full blast. For those not wintering in Hawaii, however, things are a little different. From The Green Beret Survival Guide, here are some cold weather tips (also useful if you are planning to spend time on the summit of Mauna Kea.)
“There are four basic principles to follow to keep warm. An easy way to remember these basic principles is to use the word COLD—
- C keep clothing Clean.
- O avoid Overheating. (once more: sweating is very dangerous in the cold)
- L wear clothes Loose and in Layers.
- D keep clothing Dry.”
