As a neurobiologist I'll admit that I had one conceived of neuronal mechanisms to generate this, but the increased cooling via the skin is a interesting one. If true, I'd guess that there's a neuronal mechanism anyway, as the sympathetic (or parasympathetic? who cares) nervous system can control sweat production, which would cool the skin by evaporation.<BR/><BR/>@DrJ - Great, n=2. Significance testing here we come. Interesting that there's another case similar to my own. My strong suggestion is to stay in California for apparently it takes 10 years to recover cold tolerance. But blood vessel dilation is another great hypothesis for the adaptation mechanism! <BR/><BR/>Maybe I'll actually have to try and do some searching on this. Somebody has to have studied it, right?Nat Blairhttps://www.blogger.com/profile/12684196915592792806noreply@blogger.comtag:blogger.com,1999:blog-2899165782864226363.post-30500165007608093002009-02-01T02:16:00.000-05:002009-02-01T02:16:00.000-05:00Ohhhhh yeah.

Ate every single one of my words, in an effort to keep warm.<BR/><BR/>I'd go with skin circulation changing--something in the blood vessel dilation maybe. Homeostasis is amazing like that. Could be trp channel expression--but I can't see much advantage of upregulating them in a warm climate, for example.Dr. Jekyll and Mrs. Hydehttps://www.blogger.com/profile/07005652406299754952noreply@blogger.comtag:blogger.com,1999:blog-2899165782864226363.post-89016033000804009352009-01-31T12:36:00.000-05:002009-01-31T12:36:00.000-05:00I couldn't find anything by googling but I remembe...I couldn't find anything by googling but I remember reading that when you live in a hot climate (i.e. Arizona) your skin changes to increase the amount of cooling. I don't remember the exact mechanism.<BR/><BR/>All I know is that when I go home to Buffalo in the summer and sit on my parent's deck at night when it is 70 F out, I need to put on a jacket. However, the difference in humidity has something to do with that as well.<BR/><BR/>But yes, your body does adapt.VMHhttps://www.blogger.com/profile/14805533944552740282noreply@blogger.comtag:blogger.com,1999:blog-2899165782864226363.post-57946236614967049582009-01-30T12:43:00.000-05:002009-01-30T12:43:00.000-05:00I can't take cold at all; but, then again, I grew ...I can't take cold at all; but, then again, I grew up in Florida and now live in San Jose, CA.Anonymoushttps://www.blogger.com/profile/12508594597349248576noreply@blogger.com
