From SA: Your nerve endings and brain perceive the rapid drop in skin temperature as extreme, however. Scientists are not sure why this occurs, but they think it is a signal to close down blood vessels in the skin and extremities so more blood can flow to the body’s core, to keep your organs warm and keep you alive—even if you lose a finger or toe to frostbite in the process. Wind chill is all about perception, and the wind chill index is an attempt to gauge that perception.


What is the perception of losing a finger or toe? OK a toe would probably not be lost to wind chil or even a finger. But I did meet Captain Spongefoot who was missing the end of his nose, earlobes, ends of fingers, and his lower legs, his feet were made of wood so they wouldn’t feel cold.
Ok! So it was FKN cold and he was on a high mountain in a winter storm and got in trouble. What about evaporative cooling?

so if windchill is no big deal, why do astronauts wear those big suits? when they go outside the space ship they are traveling at 50,000 miles per hour...and thats a lot of windchill! even more that Mt Washington last week.

I think it's just a fashion statement.

Wind chill makes cable bindings more “active” which puts more pressure on the tip of the ski because the wind chill shrinks all the binding components, making the binding tighter, so this changes the physics of the whole thing.

Wind chill, cable bindings, physics, tip pressure.
Can we beat the 51 page record with any of this?


No alcohol or other drugs were involved…

its my understanding that Asnes products are impervious to temperatures of any type, and therefore Asnes is the only brand of anything that anyone should be using.

Do they make fully breatheable, ultralight, yet water- and windproof shirts?

you are either a believer or you're not.

Regarding this whole discussion... some examples to consider:

A "drafty" house makes you feel a lot colder.

Creation of steam in a sauna makes you feel a lot hottwr (granted this is steam, but the idea of increased humidity still applies--add minimal amounts of water to the rocks to just increase humidity but not allow enough steam to gather and condense on your skin, same principle).

The ambient temp may be the same but the increase of, on the one hand, wind in cold temps, and, on the other, humidity in warm temps, has a marked affect.

yeah, but does Asnes make steam saunas ?
