Cold hands can be normal in winter, but if they stay cold despite layers, it could indicate a problem like Raynaud’s, poor circulation, thyroid issues, anemia, stress, or dehydration.
Raynaud’s causes fingers to turn white or blue, while poor circulation from PAD, diabetes, or heart disease can also contribute. Hypothyroidism, anemia, stress, and dehydration can worsen the sensation.
If your hands turn white/blue, feel numb, or are accompanied by other symptoms, see a doctor. Staying hydrated, exercising, and wearing gloves may help, but persistent issues should be addressed by a professional.
