You might get more info from a doctor but as far as I remember correctly if your hands and your feet are always cold your blood is lacking a basic component. I am not a 100 % sure but I believe it's iron. It's Been a while since I have seen someone ask this so can't remember correctly but I would recommend a simple blood test to see what your blood lacks.
It means you have poor blood circulation. There's a name for it, but I don't remember what it is. I have it as well. It will also make your toes feel numb. It does it to mine all the time & I'm a very hot natured person. I stay hot all the time, but my toes are often cold & numb, even when I'm sweating. You need to see a doc there are meds you can take to help. They are usually blood thinners. I'm on one cause I also have mitrovalve prolapse.
