I have had Raynauds since I was 16..am 68 now. I keep my torso warm by wearing tank tops as a base layer almost year round. I apply a small amount of Nitro-bid ointment (prescription) to my wrists and top of hands which helps dilate the blood vessels without a systemic approach. I also have a heated vest, rechargeable hand warmers. At home a heating pad helps when stationary and I use a hairdryer if my fingers start to get numb. Warm water works, but you must dry your hands quickly and thoroughly or they will chill again. The heated seats and steering wheel on my car are worth every extra penny they cost.
