How do you stop raynauds disease?

You can't. Raynauds is an incurable disease, however you could try something called biofeedback. It teaches the brain to control the bodys temperature. google it for more information. There are certain drugs available to help you cope with raynauds, however im not sure how effective they actually are but im sure they are worth a try. Other than that keep yourself warm and avoid the cold if you can. The best remedy is really just to wear warm stuff and stay inside as much as poss. in severe cases there is a drug that can open the arteries wider but it has many bad side effects so id avoid it if poss.
