Chilblains are a well-known problem of the foot within the colder climates. Chilblains are due to a undesirable reaction of the tiny blood vessels to variations in temperature. Usually when the feet get cool the tiny arteries in the skin constrict to maintain the body’s central temperature at a steady amount. Normally, when the foot warms up, these blood vessels dilate to provide extra circulation to the skin to disperse the warmth. With a chilblain, those tiny blood vessels keep on being constricted and do not open quickly. This leads to waste products accumulation in the skin which in turn result in the release of inflammatory mediators. Subsequently the arteries do open, producing an inflammatory reaction.

The main cause of this disorder with the way the blood vessels respond to the change in temperatures are not known. Chilblains simply appear to happen in some individuals and never in other people. Chilblains are more common in women which indicates that there could be a hormone aspect to them. Chilblains can, however, occur in males, but just more infrequently. They are not associated with poor blood flow because both those with great and inadequate blood flow get them. They also will occur for several years and then just halt occurring for simply no reason. The one thing which is obvious is the relationship to the cold areas. Chilblains are unheard of in the warmer environments.

A recent unique finding which has showed up lately is the fact that there's a very high occurrence of chilblains in people who have COVID-19. The coronavirus infection increases the reactivity of the vascular system, therefore it might be noticed how it might predispose to chilblains since they are a concern of the sensitivity of the small arteries. However, some have disputed this by proposing that the chilblains might not be immediately associated to COVID-19 but are more a concern with the changes in lifestyle, for example staying without shoes more in centrally heated houses because of the lockdown belonging to the outbreak. The appearance and handling of the chilblains associated with COVID-19 will be similar to the regular types of chilblains.

Although they primarily affect the toes, they do from time to time affect the nose. Chilblains to begin with appear as reddish colored and itchy patch about the toes that happen to be uncomfortable. Whenever they turn out to be persistent and continue occurring they turn into a dark blue shade.

The proper approach to chilblains should be to not necessarily get them to start with. Chilblains can be avoidable by keeping your toes comfortable with good footwear along with . If the toes get colder, after that allow them to warm-up slowly and gradually in order that the blood vessels are provided an opportunity to open up while they get used to the heat. In case a chilblain does happen, your feet still must be protected to avoid it from getting chronic. In case the skin is broken, then good wound bandages need to be used to avoid or treat any infection. There are many creams you can use to promote the blood circulation to remove the waste products which may have accumulated in the skin.
