This shows the development of patient hand under cold water, taking something from the freezer, or exposure to the cold atmosphere.
In the case of Raynaud's disease occur suddenly and temporary constriction of small blood vessels of the fingers and therefore less than the amount of blood that reaches it. Leads to the fact that this part of the pale skin due to lack of blood that reaches it. After the end of this contraction and begin expanding capillaries and blood flow back again to this region and the color of the skin due to the natural color.
