I do not have Raynaud's syndrome as far as I know but I used to get cold hands and feet when other people around me did not. Almost 2 years ago, I purchased a magnetic sleep pad and my hands and feet are much better. I no longer get into bed with ice cold feet and my hands no longer go numb in air conditioned rooms. Check out www.magneticosleep.com for more information. If you are interested in buying one of these and don't know a local dealer, please reply to this post with your email address and I can help you.
