I do wonder how much of this is genetic. My ancestry is Celtic (Scottish on one side, Irish the other) and I have a high resistance to cold, until I lived with my partner I’d have the the windows ajar even in winter and rarely put the heating on, I’m rarely cold even when cycling long distances on days with the temperature around zero and I wear t-shirts year around, I find jumpers and shirts stifling in any normal t…

How does your body react when in tropical or 80F?

When I was in college I met a fella from Michigan. The first “winter” here in Florida he was wearing shorts and laughing at us wearing sweaters and coats. That summer every time I saw him he was soaking wet. The next winter he was wearing sweaters also.

Something about tropical heat will do that.

You’re one of them ! “They're almost like normal humans, except they have no knowledge of what it means to be cold. ” — http://absurdnotions.org/F1992.html Of course, there are those other people as well… http://absurdnotions.org/an20020702.gif

I am the latter.

I wonder what genes regulate adaptability or comfort to different climates? How much is simply environmental (perhaps epigenetic)?

Anyone know the rationale of people that make a room freezing with air-conditioning and then wear a jumper in that room to warm up? I know a few people like this and I’ve always been curious if it’s almost like some kind of glitch in their body temperature regulation, like it might be easier for them to regulate their body warmer or colder but not the other way around or something.

I'm Vietnamese and I was born and still live in Canada. My body has adapted to the cold quite well and I prefer it over the summer heat. This makes me feel that ancestry is not a part of cold resistance.

Regardless of your anecdotal experience, adaption to cold is certainly genetic to a large extent and the literature seems to support that hypothesis.

Earlier quoted context omitted.

The article mentions that plastic bags work better than emergency "space" blankets since they block moisture and thus evaporative cooling. A large industrial trash bag is part of my emergency supplies on cold backpacking trips. It's cheap, weighs almost nothing, and provides protection from both radiative and convective cooling.

I'm surprised. I've lined up before races in the cold and I've found an emergency blanket keeps me warmer than a trash bag. I've tried both. Neither beats used sweats from Good Will, but that's too much to run with.

You're supposed to pretend your the garbage and climb into the bag - creating a closed system where you keep the lost water warm.
