Raynaud's Syndrome: Cold weather's hidden danger for millions

Raynaud's syndrome affects 10-20% of adults, especially women, causing fingers or toes to turn white, blue, or purple in response to cold or stress due to blood vessel spasms, leading to pain and numbness. Dr. Alireza Meysami from Henry Ford Health emphasizes warming the body, managing stress, and avoiding smoking, caffeine, and alcohol as preventive measures, while also noting medications can help severe cases but must be used cautiously due to blood pressure effects.
