Imagine stretching out your hand on a cold day and watching your fingers go out like a light. 🥶
That is exactly what happens to those living with Raynaud’s syndrome, a condition in which the small blood vessels in the fingers and sometimes the nose, ears, or lips react excessively to cold or even stress. The vessels constrict, blood stops circulating as it should, and the skin changes from its normal color to pale white, then blue, until circulation returns and everything suddenly turns red.
It is temporary, but visually striking: the body showing in real time how it responds to something as simple as the weather or nerves. 🩸
