I have this, and it can be made worse by a low body weight. Anyone who is underweight, or low weight, will feel colder than the average bear, as you don't have enough fuel to burn to keep you warm. Other factors include Stress, as this causes an adrenaline rush, which causes the blood vessels in your extremities to constrict, caffeine, and cold environments. Keep your wrists, neck and groin warm. Exercise helps relieve the symptoms, although not too much, and be sure to wrap up afterwards.

I have this too, it runs in my family so could have something to do with that but i never noticed it until i was 'underweight'. I find that air con makes it the worst!!

Yup, I've got it as well.

Funny this topic should come up as I sit here trying to warm up my nose with my freezing cold hands, while my feet are freezing right off.

I wonder if it has anything to do with low blood pressure. I have naturally low bp and even when I was at a normal weight, I still got the symptoms of Reynaud's.

Very annoying, isn't it.

it has nothing to do with low blood pressure or low body weight. Renaud's is an autoimmune disorder that causes the digits, toes ears, nose to become cold , white and stiff for periods of time. My dr. has assured me even when my toes look as though they belong on a corpse that they are getting circulation just fine and will return to normal. it can be very painful yet incurable. do you have any other autoimmune disorders?

i forgot. If you are underweight and have an eating disorder, your body sends all necessary nutrients and blood supply to your internal organs to help you survive. that is not Renaud's syndrom.

Thanks everyone good to know!
