I think it is a personal thing. I suffered from Febrile convulsions as a child & I still have a heat problem. Never noticed hot flushes at menopause as I'd always had them. I never sleep with even a stitch of clothing on & usually under a very light cover. My younger son is the same. 3 of my GC never feel cold & the other 3 do.
I have a friend who does not even HAVE a coat & another who wears long sleeves all summer.
It's not an age thing I don't think- it is just hw you are made.
Mind you I hate drafts!
Shops and Cafes no longer here.


She always wraps up warm as we used to live in the tropics and she is never too hot here!
