Reynauds is a circulation prob, the blood struggles to get to the tips of fingers and toes, so they are cold a lot of the time (its fun at work when you accidentally touch someone, asI dont realise how cold they are at times!!), Heatbands are a product that Charlotte posted a link to, they are supposed to trap the heat so you dont have cold hands, we shall see when they arrive!! Its another good reason why i like the summer, as I Can tolerate the heat better as my body temp is colder to start off with, so I Can sit out longer than some people.
