The tiny blood vessels on the skin surface get narrow at cold temperatures. Once a warm temperature is reached, some vessels widen much faster than the surrounding ones and cause the blood to leak out of the vessel.Risk factors for the development of this condition include:Clothing that is tight or exposes skin to coldGender - more common in womenWeight- people weighing 20% less than what is expected for their heightSeason- more common in cold, humid areas than in freezing temperaturesPoor circulation/ vascular diseasesRaynaud’s diseaseFamily historyAutoimmune disease called lupus The exact cause of this condition is unknown but it is a result of an abnormal reaction of the body to cold exposure followed by rewarming.
