When exposed to cold, the blood vessels in your toes are naturally inclined to constrict. This abnormal response to cold, damp weather should not be confused with frostbite, an injury that occurs when the skin and surrounding tissues freeze, which is an entirely different ailment brought about by extremely cold temperatures.Ĭhilblains are caused by the blood vessels in the affected region (in this case – the toes) mishandling the sensation of cold and humidity even if those temperatures are significantly below freezing.
