Is it normal to always have very cold hands

My hands are always cold even if its hot outside. In the winter my nails are always blue everyday because my hands are cold. I think ive always been that way because as a kid I would cry if I had to do outdoors activities in the winter because my hands would go numb from cold even if I wore double pair of mittens and same with my feet. I still get anxiety if I have to be outside to do something in the winter because there is no way I can keep my hands or feet warm. Everytime I have seen a nurse for something I always get comment if they touch my hand/s "oh my god what, you are so cold!!" like they are very shocked and surprised how it is possible.
Is this normal or what is wrong with me?
