I have a milder form of the same phenomenon and find that workman's style fingerless gloves (I use DeWalt Technician Fingerless Gloves[0] and can vouch for them.) are enough to reduce it to a tolerable level. They are thick enough to retain warmth and highly durable but leave the fingertips unimpeded for mousing / typing. In your circumstance, I'd look into USB-powered heated gloves as an option as well, e.g. [1]. If that alone isn't sufficient, some have removable heating elements that you could probably transfer over to the heavier fingerless gloves mentioned above.
