I'm inclined to actually agree with as simple a solution as Nige (maybe with some scientific jargon peppered in).<br /><br />cheers,<br />meAnonymoushttps://www.blogger.com/profile/09784507668616981650noreply@blogger.comtag:blogger.com,1999:blog-7890604293949783916.post-3499892027270667682010-10-17T20:15:54.577-05:002010-10-17T20:15:54.577-05:00Sorry it has taken me so long to get back to you N...Sorry it has taken me so long to get back to you Nige. What you say does make sense, but I couldn't see that it was addressed in any of the articles I've referenced.<br /><br />They talk about internal temperature (which does not change with cooling), trunk temperature (which does change, but about the same in both groups) and peripheral temperature (which also changes but about the same in both groups).<br /><br />In the context of these papers, "insulation" is a technical term that addresses a change in temperature distribution from one part of the body to another. Fat people seem to do more of this than thin people.<br /><br />However, it is surprising to me that the investigators do not talk about insulation in terms of an R-value as you would in physics to measure the ratio of the temperature difference across an insulator to the heat flow per unit area. Even though there is blood circulating through the fat, it seems that there should be some way to measure how much insulation the fat provides under standard conditions.Stargazeyhttps://www.blogger.com/profile/09566854038842118222noreply@blogger.comtag:blogger.com,1999:blog-7890604293949783916.post-11611533456722853992010-10-13T05:21:20.554-05:002010-10-13T05:21:20.554-05:00Hi.

Fatter p...Hi. How's this for an explanation...<br /><br />Fatter people have a thicker layer of thermal insulation than thinner people. Therefore fatter people don't need to increase internal heat production as much as thinner people when the external temperature drops.<br /><br />Cheers, Nige (a fatter person who doesn't feel the cold but who overheats in hot weather).Nigel Kinbrumhttps://www.blogger.com/profile/03368973941328529619noreply@blogger.com
