The Raynaud's Phenomenon

Raynaud’s happens when cold or stress causes the small blood vessels in your fingers to tighten too much, briefly reducing blood flow. This can make the skin turn white or blue and feel numb or tingly. Warm water helps those vessels relax and reopen, allowing circulation to return. As the blood flow comes back, the finger’s natural color and warmth gradually restore.
