Those living in cold and humid climate may have experienced chilblain sometime or the other in their life. Chilblain or perino as it is called in medical terminology is said to be vasospastic reaction to cold and dampness in susceptible individuals. Chilblains are small red and itchy swelling on skin which can become painful and dry out leaving cracks and fissures on skin.
Anyone can suffer from chilblains, but young adults working outdoors in cold and damp places and people who do not wear socks and hand gloves during winter are mainly affected. It can also develop in elderly living in cold climate with compromised blood circulation.
Mostly it heals in two to three weeks on its own as the weather become warm. It does not cause permanent skin damage. The best treatment for a susceptible person is to avoid exposure to cold by wearing warm clothes and covering the exposed skin area.
What Are The Causes Of Chilblains?
The exact reason for chilblains is unclear but it is certainly related to abnormal reaction of the body to cold atmosphere. Chilblain occurs in areas of body that undergo sudden change in temperature from cold to heat. For example a person may develop chilblain if he places his hands on fire after exposure to cold and humid atmosphere.
Sudden and quick heating after exposure to cold causes capillary dilatation under the skin. However, the larger blood vessels take time to dilate. Hence blood in smaller vessels (capillaries) leak out in the tissues beneath the skin causing redness and swelling. Following factors increase the susceptibility of developing chilblain:
- Exposure to cold and then sudden warming of the exposed part.
- Being women, the reason for this is not known.
- Underweight individuals are greater risk of developing chilblain in cold and humid climate.
- Chilblain occur more in cold and humid climate but may not develop in areas that are freezing cold probably because in this areas people are well covered and take adequate precautions against cold.
- Wearing tight footwear and socks can increase the risk of chilblain in cold and humid climate.
- People suffering from Reynaud’s disease are more susceptible to develop chilblain. Reynaud’s disease affects blood vessels of extremities.
Signs And Symptoms Of Chilblains
