      This Might Be Why Your Hands Are Always Cold



      To say my body doesn’t do well in the cold is an understatement. When the temperature drops, my fingers freeze, and often turn deep red, followed by white. On especially exciting days, they’ll look a little blue. “Cold hands, warm heart,” my mom used to tell me.


      Growing up in sunny Southern California, this rarely happened—mostly just on ski trips or when I’d spend too long in the ocean. But when I moved to New York for college five years ago, my blue hands became a winter mainstay. I’d never lived in a cold climate, so I assumed this happened to everyone in frigid weather.


      Turns out I assumed wrong. On a trip to Chicago to visit extended family this past Thanksgiving, I went for a walk and returned to my aunt’s house with my signature blue fingers. “Oh, you must have Raynaud’s,” my aunt said. I must have what?


      The average person can go into chilly weather and get by without gloves, their fingers would just get a bit cold. But someone who has Raynaud’s has a much more extreme reaction. If you touch their hands, you can tell the difference. Even in a moderately cold environment, they have white, ice-cold hands. In addition to getting cold, if you have Raynaud’s, your hands might turn white, then blue, and red when you start warming up again. But not everyone with Raynaud’s exhibits all three colors, or in that exact order. You might also experience these symptoms in other extremities including your ears, nose, lips, and even nipples.
