Built-in heat and air
It seems that since my cardiovascular system has become more efficient from exercise that I not only can withstand cooler temperatures more easily than the average (sedentary) person, but also warmer temps.

Could this be because the blood supply more effectively regulates heat levels, distributing warmth when needed and removing excess heat when it's hot out? That might be an explanation.

Does anyone else notice how the sedentary folk around you complain more bitterly about extreme cold or heat (and dress accordingly) than you?

You are correct sir. As is my wont (what the heck does wont mean anyway) when I was a regular runner years ago I read a great deal on the subject. Regular exercise forces your body to adapt. How you adapt depends on the type of exercise you do. Weight lifters lift heavy weights so their muscles get microscopically torn and rebuilt and add fibers in order to cope with the stress. Sprinter develop additional fast twitch muscle fibers to fulfill the need for speed. Aerobic cardiovascular exercise causes your body to add slow twitch muscle fibers for endurance as well as additonal tiny blood vessels and improved sweat mechanism for heat dissipation. If you cover up you keep the heat in and stay warm. When you uncover the heat escapes more efficiently and you are cooler.

I notice the same thing. People are here complain about how cold it is even with their under-the-desk heaters. I turn on my fan because it's 74 F in here!

I think a big part of it is getting used to temperature fluxuation. Earlier in the winter, I remember freezing on the first sub 20 degree morning. Now, I routinely ride in the same temps, wearing the same clothes, and I don't get cold at all.

I have noticed the same thing as well. I lived in New Orleans, where my more sedentary friends would sweat heavily while I sat comfortably. I now live in Montana, where I am comfortable with my home air set at 64 and rarely feel extremely cold.

I also wonder how much mental playes into it. I push myself everyday, and have convinced myself that I can handle just about any condition (wind, rain, snow, heat). Sometimes if I start feeling chilly, I just stretch my neck and convince myself it feels good, and you know what?... It does!


I ride. I fall down. I get up.
Meanwhile, I keep dancing.

Well, I seem to handle our "so-called" winters better than most folks, but I still hate summer. I always thought it was just the time I spent in the cooler temperatures of the Hinterland.

I make fun of the sedentary folk where I work when they bi#@h about the heat or cold weather.

BTW, I went to lunch today with a few guys I work with who tend to eat too much. There were 5 of us from my office who went to eat buffet at Pizza Hut. Two of the guys were having a contest to see who could eat the most. One guy at 17 pieces of pizza and 10 breadsticks. I couldn't beleive it when this guy didn't spend all afternoon in the crapper.

I think it's a manliness contest for those whose jungle is one of chain stores and television and fast food franchises. I remember a friend of mine expressing the all-you-can-eat ethic as "eat through the pain!" -- X-treme sports for the Nintendo nation. I can almost see the advertising campaign now...beefy guys at an all-you-can-eat buffet, sweating and grimacing as they try to force down just one more slice of pizza, while the crowd goes wild...

We all have to find our challenges somewhere. And yes, I believe the body adapts. Somewhat.

But back to the thread...

Myself, I haven't noticed a change, although maybe it's too soon, or maybe I'm coming from a very different baseline than the rest of you -- I've always tended to get cold easily, and even though I'm active I'm still prone to cold hands and feet. In the summers if it gets too hot, I have a tendency to accumulate fluids -- i.e., I swell up -- so I'm quite happy to live in a relatively mild climate. I don't know if it's gotten better as I've become more active...maybe.

I'm told that I seem to radiate an unusual amount of heat when I'm sleeping, although I'm generally the one who complains of being cold.

It might be a surface area to volume thing. I'm little.

or maybe it's a girl thing -- do women notice being too cold or too hot more than men, on average? perhaps the physiology of thermoregulation in human females has some quirks that make a difference. I don't know -- I don't know if there's even a difference. It might just be me.

At equivalent levels of fitness, men have a higher muscle mass than women, and a higher BMR (if the women isn't pregnant). Muscles generate heat, even just sitting. Low body fat women that haven't done strength training to build their muscle mass are hit with a double whammy: they produce less heat, and lack the insulation to retain it well. Then the final chill, women are more prone to Reynaud's syndrome in which chilling causes the capillaries in the extremities to super constrict. If your fingers turn white when cold, then bright red and quite painful as they warm you probably have it.
