What are some home remedies for raynaud's disease?

No special remedies. There are no special home remedies one can use to prevent or treat raynaud's symptoms, but things that keep one warm are helpful. Examples include: a well insulated home with the heater set at a warm temperature, a circulating hot-water system in which the water is hot right away from any faucet, not touching cold things that come out of the fridge, drinking warm soup, using down comforters, etc..
Wear Gloves. Wear gloves when ever there is the possibility of touching something cold or being in a cold environment.
Warm enviornment. Keep your hands warm, keep temperature at optimal level. Avoid emotional stress.
