We don`t adapt (called adapt-ation) to changes in temperature so well as we age, it is a natural process
Personally I don`t wear man-made clothes in the cold months, only wool, silk for vests and linen, these fibres are very well suited to cold months. I make my own clothing, I could not find a woollen dressing gown so made my own several years ago, zip down the front, pockets and a hood. No static and nice and warm. Layering is key, trapping warm air close to the body
I dont do any exercise outside in the cold, it is not good to breathe cold air into lungs and I need my mouth open up hills, so I don`t go. I just do a bit of re-bounding instead, indoors
Only a few years ago I could go on a cycle ride and see frost on the verges but now I am 77, my bikes are put away for october to april
Got to go with the flow and my hibernation mode is fully in action now. Indoors, lots of hobbies, lots of stored foods and just wait it out while feeling lucky to have central heating and a well insulated home
Regarding the OP, yes to feeling the cold more
