Anyone know why my hands (and sometimes feet) are always warm? ?

I'm 19 and female.

This is sort of a weird question, but recently I took notice to how my hands are always strangely warm, and at times it gets uncomfortable. My feet does this as well, usually when I am up and walking around in the cold. It's nice not having cold ligaments (like my peers) but I never knew why I'm such a furnace (as my mom puts it). When they're warm, they look blotchy and red. The only times they are cold and pale is when I'm nervous or if I'm doing a task where the blood supply to my hands are limited, such as typing this post. At night when I try to sleep, my whole body gets warm (my face especially) and I have to turn a fan on. There's no fever or night sweats. I'm obviously not dealing with menopause

Google says it's either palmar erythema or erythromelalgia, however my blood tests always come back normal as well as my liver tests but on occasion my enzymes will be elevated. I'm not an alcoholic. My thyroid is good. No diabetes. I can literally recall a time in middle school where I was on the bus and my hands were so warm, so this isn't something new. I even remember my mom telling others that I am "hot blooded" or "warm bodied" or I'm "like a furnace". I wouldn't think this is erythromelalgia because they don't necessarily burn.. they just feel so warm. Is this some kind of normal anatomical thing? Heat intolerance maybe?
