Hello planb and thanks for posting.
It is important to keep the core body warm. Dress in layers. Mittens are much better for fingers than gloves. Have you looked through our forum archives under Hot Products? The archives can be found by placing your cursor over discuss at the top, right hand side of this page.
When warming techniques don’t work it may be time to talk to your doctor about medication. I hope you will continue to post about your experience with Raynaud’s.
