Chilblains Causes

Chilblains are considered as an adverse reaction of the body after being exposed to cold. The condition generally tends to develop in those areas of the skin that have been exposed to cold and then warmed a little too rapidly. For example, chilblains may develop when cold hands are suddenly warmed by placing them in front of a fire or directly directed at the heater.

Sudden warming of the skin leads to sudden enlargement of the tiny blood vessels in the skin. This expansion is too sudden for the adjacent larger blood vessels, and it cannot alter efficient to handle such a change. This results in a bottleneck type of situation wherein all blood vessels are vying for space, therefore resulting in the leakage of blood to the surrounding tissues. The exact cause of such a reaction of the skin is not yet known.
