If you find yourself staring at a white finger, the goal is to encourage blood flow back to the area gently.
-
Wiggle and Massage: Move your fingers in “windmills” to use centrifugal force to push blood to the tips.
-
Warm (Not Hot) Water: Soak your hands in lukewarm water. Avoid hot water, as the lack of sensation during an attack could lead to accidental burns.
-
De-stress: If the trigger is emotional, deep breathing exercises can help the nervous system relax the constricted vessels.
-
When to see a doctor: If the attacks become more frequent, if you notice skin sores/ulcers, or if the color change is accompanied by joint pain or rashes, it is important to consult a physician to rule out secondary conditions.
