Nice. Don’t know!
We’re made differently. Our fat reserves are different, so we will have different levels of “insulation”. Someone will also feel the cold if their blood vessels are, on average, closer to the surface of the skin. Some people will respond to cold differently, also. So if two people are at the same temperature, and their nerves are sending the same signals to their brain about temperature, that one person’s brain will interpret those signals as “Hmm, I’m a little cold” and the other person will say “Ouch, I’m FREEZING”. Other things can include basic differences in metabolism – some people burn energy faster than others and that can generate heat.
So a lot of this is genetics. I know it also varies over time. I’m from the north of England, and don’t feel cold, really. My wife is from South Africa and wants heat. It’s usual that I’m warm and she’s cold, but there are times when she’s weirdly fine and I’m freezing. So that’s mostly genetics, but can be influenced by body chemistry, which can be influenced by what you eat and other things.
It depends a lot on how good your circulation is. Warm blood from the core of the body gets moved out to the limbs. Poor circulation means that the extremities (nose, toes, fingers) don’t get as much of this nice warm blood supply.
