Understanding Raynaud's Phenomenon: Key Facts and Information

Raynaud's phenomenon is a condition that causes reduced blood flow to certain body parts, usually the fingers and toes, in response to cold or stress. It is often triggered by cold temperatures or emotional stress, causing the affected areas to turn white or blue and feel cold and numb. The condition is thought to be related to the overreaction of blood vessels to cold or stress and may be linked to autoimmune diseases. Treatment involves keeping warm, managing stress, and, in severe cases, medication or surgery.
