Many people are surprised to hear that frost can cause an allergic reaction similar to eating citrus fruits, or inhaling ragweed, for example.
Not so long ago, little was known about this problem even on the Web, but as it turned out, every third person suffers from an atypical reaction of the body to low temperatures. The most difficult cases can include asthma, fainting, and even anaphylactic shock in a person. In order not to succumb to the effects of unpleasant symptoms, we propose to understand the causes of this phenomenon.
What is cold allergy and why does it occur?
Cold allergy is an atypical reaction of the human body to low air temperatures from external sources. Experts have not yet been able to find out what is the reason for this anomaly. Some of them believe that the whole thing is in cryoglobulins, which, when exposed to frost, start histamine to work, and he, in turn, an allergic reaction.
Diseases of the genitourinary and respiratory systems, as well as various infections and problems with the gastrointestinal tract (gastritis, dysbacteriosis, etc.) can also become important catalysts for the development of cold allergies. In general, almost any health problem can cause such a reaction in the body.
How to understand that it is an allergy to the cold?
Of course, as with other diseases, cold allergies have their own symptoms:
- Redness and itching in areas of the skin that were open;
- Swelling of the lips and tongue;
- Tearing and redness of the eyes;
- Headache and signs of SARS.
Depending on this, there are also types of cold allergies:
- Allergic reaction of the whole organism.
As for cold urticaria, it is the most common variant of events. Usually, redness appears on places that were not covered with clothes. But it can also spill over into areas that were fairly well protected. These places are unpleasantly itchy, and may become blistered. If compared, then most of all this phenomenon resembles a lesion from nettles. In some people, due to the characteristics of the body, the skin can also become dry and flake.
Conjunctivitis is known to affect the eyes. A person suffers from pain and severe pain, everything is accompanied by tearing. Often, right in the cold, a runny nose and sneezing can begin — this is how rhinitis manifests itself. When you get into a warm room, all of the above symptoms disappear.
Cold asthma can be distinguished by the appearance of shortness of breath or a feeling of lack of air. The thing is that the lumen in the bronchi narrows when exposed to cold, and the body falls into a state of shock.
Some people who suffer from certain ailments experience allergic manifestations to the cold in a more complex form. This may include chills, loss of consciousness, swelling of the extremities, rapid heart rate, and pressure problems. Only a few cases in world medical practice ended in death.
How is it treated?
Just like ordinary allergies, cold allergies are treated, first of all, with preventive measures: all options for damaging skin areas with cold are excluded (mittens, scarves, hats and fashionable balaclavas — to help). Medicines do not completely eliminate the problem, but only affect the symptoms.
In order not to overcool, it is worth choosing clothing items mainly from natural fabrics. Before going outside, moisturize your lips, and if a runny nose or tearing occurs, massage your cheeks, ensuring blood flow to the affected areas.
Cold allergies don’t just happen. It may indicate a decrease in immunity, stress, or pathology in the human body. The best solution for cold allergy symptoms is to visit an allergist.
