Jeune Koq, you mention jogging and feeling cold at -5 celsius and being fine above freezing, even when it's raining. What climate do you live in? I am having trouble finding this information on the internet, but in my personal experience the weather that plays between freezing and not freezing is actually much more uncomfortable than the weather that just stays way bellow freezing all the time. This is largely because in the former case there is much more humidity in the air.
One winter I lived in a heated cabin in Southern Ohio. It was a very rainy winter, it felt very cold, i shivered a lot and even developed a slight case of walking pneumonia which is one of two times I ever suffered from pneumonia symptoms. Two winters later, the winter before last, I lived in Northern Michigan. I lived in a insulated loft in a closed barn without heat for 2/3 - 3/4 of that winter after I became disgusted with the smoke that would sometimes waft out of the wood stove. The temperature went above freezing on two occasions that winter for a few hours. I shit you not 17 degrees felt warm, almost like spring time. I would walk 6 miles at 4 in the morning when it was -20 to -30 fahrenheit (that's -29 to -34 celsius) with the wind howling at 20-30 miles per hour. I wore jeans with cotton long underwear, a shirt and a couple wool sweaters with a coat, a hat and gloves. I had a -30 degree rated sleeping bag I used as a blanket and slept with two long hair cats. Never did I feel acutely cold. Never did I shiver. Not until the spring rains came lol. Never did I get sick that winter.
Tyler Durden I think you still keep saying that smaller people are more adapted to the cold and have less surface area to body mass. Albeit I can't find where you said it but I think you said it. Smaller people have more surface area to body mass.
