How Long?

[notyoueither]

I was just listening to radio, waiting for a hockey game, and the radio guy said that an athlete uses a cooling chamber for some nonsense like strengthening his bones.

The claim was that the athlete stands in a chamber cooled to minus 275 degrees F for a couple minutes at a time. Aside from the costs associated with such a training regimen, it struck me that the man would not survive that for even 60 seconds. I imagine your skin would be insta-freeze-dried, or something like that, and you would die in very short order after that.

I'm sure the radio guy was misreporting something he read somewhere else, but it made me wonder how long a hairless mammal could survive if exposed to a temperature like that. I thought it would be a suitable question to bring before the wise men and women of Poly, so here it is.

-107 celcius...about 5 seconds max before they suffered permenant damage? Probably less IMO.

9 inches.

note: above post was a poor attempt at humor by the poster known commonly as Dis. It was used to illustrate the silliness of responding to a thread based on thread title alone, and to illustrate to those posters who shall remain nameless who like to post in a thread without reading the op or comments. not that I ever have done that.

[Asher]

So it's not 9 inches?

[Dis]

in my dreams maybe

[snoopy369]

Dis is more like 10.5". You haven't seen his ad for Natural Male Enhancement?

[Dis]

no it's closer to 9 now. I had to get penis reduction surgery.

[snoopy369]

Ahh, I'm just not keeping up with the times anymore

[ZEE]

can we get back on topic please, i want to hear moar about the cooling chambers.

[notyoueither]

I see we've made good progress here. Good work!

In 45 subjects, 154 frostnips of the finger were induced by cooling in air at -15 degrees C with various wind speeds. The mean supercooled skin temperature at which frostnip appeared was -9.4 degrees C. The mean skin temperature rise due to heat of fusion at ice crystallization was 5.3 degrees C. The skin temperature rose to what was termed the apparent freezing point. The relation of this point to the supercooled skin temperature was analyzed for the three wind speeds used. An apparent freezing point for a condition of no supercooling was calculated, estimating the highest temperature at which skin freezes at a given wind speed. The validity of the obtained differences in apparent freezing point was tested by an analysis of covariance. Although not statistically significant, the data suggest that the apparent freezing point with no supercooling decreases with increasing wind velocity. The highest calculated apparent freezing point at -15 degrees C and 6.8 m/s was 1.2 degrees C lower than the true freezing point for skin previously determined in brine, which is a statistically significant difference.

I found this at 2 sites, this was PubMed, so it must mean something to someone. It didn't show time of exposure, tho.

"Previously determined in brine" by the Nazis in WW II. Bones would be positively affected and preserved at the temperature suggested. However, any attached LIVING flesh would be severely damaged. So only do that to detached bones. Those don't usually make for good hockey jocks.

I imagine that cold THAT intense would make it a good deal shorter, if it didn't shrivel up and fall off entirely.

I need one of those chambers. Cold showers aren't cold enough for me.
