It is a condition that affects millions of people. (Page 2 ) | April 5, 2025

Dr. Melisa Lai Becker, a physician specializing in emergency medicine, explains: “The average person can go out in cold weather without gloves—their fingers may just get a little cold. But with Raynaud’s, the extremities can turn white and feel icy, even in moderately cold environments.”

What happens during a Raynaud’s episode?

A Raynaud’s episode generally occurs in three distinct phases:

1. Pallor (Ischemia):  Blood flow is drastically reduced, causing the affected areas to turn white.
2. Blue Tint (Cyanosis):  Lack of oxygen in the tissues can cause a bluish discoloration.
3. Redness (Reperfusion):  When blood flow returns, the area may become bright red and warm, or even painful.
