Raynauds syndrome

My youngest daughter has reynauds and her hands can go completely white even on what I consider a not particularly cold day

Not scared when my hands turn blue but I try to be prepared for all cold events as I have had Reynauds for many years.
I keep a pair of clean leather gloves in my shopping bag and pop them on for 'freezer retrievals' ...... it really helps.
In winter I use the pure silk glove liners which keep my circulation going.
I never, ever drive my car without gloves on. Its the only way to keep the feeling in my hands.
Hope this helps.
