Do any of you fellow anxiety warriors deal with chronic cold hands? If so, how have you had success?

I’m not talking about something extreme like Raynaud’s with numbness and discoloration. My issue is that my hands just get cold (especially in the winter) and have a hard time staying warm. It seems anxiety and stress related because they’re worst when I’m working (my job can be stressful) but never cold when I’m sleeping, and seem to warm up best in the evening when I’m not at work and am doing something I just enjoy (e.g. reading, video games, movies, etc.) 

I’ve been reading up on some biofeedback exercises (e.g. belly breathing) to fend off the cold hands when they recur but would love some ideas if you’ve had similar issues!
