Here are some things I've found useful (male with primary raynauds)
Offer to wash up -great way to warm hands
In the car, block up the rear warm air vents so all the warm air is directed to feet / hands
Buy a plug in demister for the car -saves the warm air for you and not the windows
Get used to doing ALL outdoor jobs in fingerless gloves or full gloves
Red alcohol (wine, port) really does give the boost you may need before going into cold bedroom (obviously adhere any individual health warnings!)
Avoid coffee like the plague - go for de-caf
Thin fingerless gloves inside other gloves ensure less heat lost
Vests 1 size too big cover the lower back and are less obvious with open neck shirts
If cold 1st thing in morning, go up / down stirs 5 times - good for the heart also
Dog walking-don't feel so daft all togged up in hats and wellies if dog at your side
Work out which meds work for you and see how quick / slow they kick in i.e. better before or after food(though follow any guidance from GP / Pharmacist) Discuss with GP re alternatives
As winter progresses if I think of any more I'll add.
Good Luck
