Why am I reacting to cold weather so badly?

I am a 23 year old man and I suppose that how cold you feel on cold weather depends a lot on your weight and this is where things get unusual. For the last few years I used to be somewhat bellow the normal BMI and was slipping into anorexia region and I felt ok in winter, however at least a year ago I got back into normal BMI weight range, I started eating a lot (meat, soup, vegetables, everything) and now I am almost at the middle of the ideal BMI range, which is great, except…that instead of that helping me feel warmer during these cold days (usually slightly above 0 c - 32F), I think that I never in my life reacted so bad to cold.

Today for example I went for a 3 minute walk to the market, I was wearing warm clothes, jacket,etc. and I still shivered a little (not a lot, but still…), even without any wind blowing and with me putting two hoods on my head, while people around me mostly didn’t even wear any hats or hoods. I don’t have any medical conditions and the only thing that may be of some importance is the fact that I don’t exercise at all, but I never really exercised for the most part of my life and I didn’t feel cold as much as I do now.

So is it non-exercising (and if so, why exactly) or something else?

I really couldn’t tell you Jake. But FYI, I reported this for a forum change. Probably get more replies in IMHO.

Are you anemic, maybe? Have your blood tested.

Moved from Cafe Society to IMHO.

Doesn’t matter what you or other people were wearing. What was the temperature/windchill?
