Chilblains result from exposure to cold vessels to constrict. Therefore, the deoxygenated blood in the tissues become bluish and fresh blood is not able to get adequate access to the affected parts. In cities universally centrally heated such as in the United States, chilblains are a rarity. But in cold places where this is not the case, they are very prevalent such as in the United Kingdom.

During winter weather, it is more common and in the cooler southern areas. In moderate climates, chilblains are almost entirely preventable by wearing sensible clothing, and avoiding prolonged periods of time in very cold situations. In severe instances, the burning itch chilblains may lead to blistering and ulceration. Sometimes urgent attention is needed, but this is unusual.
