What is the most common cause of chilblains?

Chilblains are lesions on the skin which occur on the feet that are more prevalent in the cooler climates. Understanding the explanation for any condition will go a long way to help being aware of what is happening with them, how to prevent chilblains and the way to take care of them. This is definitely the case with chilblains. While they just happen in cold climates, they may not be actually caused by the actual cold. Lots of people who do not have them get cold as well and they do not have chilblains. Similarly, some people get chilblains with even little changes in temperatures and it not too chilly. This means that there is a lot more going on than only the cold that usually gets blamed for producing them.

In the skin there are a lot of tiny blood vessels (the microcirculation) which help control temperature within the body. When we become chilly, these blood vessels shrink in order to save heat deeper in your body. If we are warm, these arteries open up and convey the blood closer to the surface in order that we will disperse heat for cooling your body. This is an important normal functionality. With a chilblain the blood vessels close up like they normally should, however when the foot is warmed up, the capillaries continue to be closed when they shouldn't be. This means that waste products begin to accumulate within the skin and there is no blood flow to get rid of them. This causes an inflamation related response along with the release of chemical substances making the chilblain painful and itchy. Ultimately the capillaries do open up and the rapid rush of blood to the chilblains triggers further itchiness and also pain. The primary look is usually a dark bluish lesion, but this might be a reddish appearance following that rush of blood. If this process is recurring every day, then chilblains may become a chronic sore.

Just the reason why in certain individuals the blood vessels remain closed for longer in wintry environments in unknown. Chilblains tend to be more common in women, suggesting that there could be some kind of hormone affect on the pathology. On the other hand, males do will also get them, thus if it is hormonal linked, then that is not really the only issue. Astonishingly for something that is so prevalent, there is fairly little research been done to try and research this further.

Applying this knowledge of the cause might help people prevent and treat chilblains. Needless to say an important thing to do will not be allow the feet to become cool and maintain them warm. If they do become cool, then it is vital that they are warmed up very gradually so that the microcirculation to get a chance to respond to the higher demand in the skin and the blood vessels can easily open up to meet that requirement. Because of this the waste products will not accumulate and the inflammatory reaction process is not commenced. Once that process does start, then your course of treatment needs to go on to reduce that inflammatory reaction process and help remove those waste elements which have accumulated in the skin.
