Allergy to cold is a manifestation of various allergic reactions that occur under the influence of low temperatures. This pathological condition is more often observed in women, and usually the first manifestations fall within the age interval from twenty to thirty years. Allergy to cold in a child is rare. Symptoms of cold allergy can develop on the street during the cold season, in case of contact with cold water (washing dishes, bathing in a pond), with cold food and drinks and in a strong cold wind.
As it is paradoxical, but many people susceptible to these allergic manifestations, even the morning coolness can cause such unpleasant manifestations as lacrimation, redness of the eyelids, itching, runny nose and skin rash.
Official medicine recently recognized the existence of such a disease as an allergy to cold. People who suffer from this disease have difficulty breathing at low temperatures, they have reddening of the skin, they start coughing. However, frost is not the only cause of suffering for people susceptible to this type of allergic reaction of the body. Such people react very sharply to cold water, drafts, transitions from warm to cold places and vice versa, dampness. Even on a hot summer day, if such a person sits on a bench with the shade of trees, he may develop symptoms of an allergy to cold. On the everyday lifestyle this condition imposes a lot of restrictions, such people need medicines almost constantly
Cold Allergy - Causes
Allergy to cold develops as a result of violation of human immune defense. This type of allergy can develop as a consequence of the occurrence in the body of various debilitating diseases that change the process of metabolism and affect the whole body as a whole. Such diseases include endocrine diseases ( Graves' disease , etc.), hemoblastosis ( blood cancer ), systemic lupus erythematosus, etc. In some cases, even such common chronic diseases as sinusitis , chronic cholecystitis, intestinal dysbacteriosis and caries can become a catalyst for the development of allergies to the cold. Provocative for the development of cold allergy may be some infectious diseases - mycoplasmal pneumonia, mumps , infectious mononucleosis, rubella, measles
Cold Allergy - Symptoms
The signs and symptoms of an allergic reaction to low temperatures can be different. The most common common form of allergy, which manifests itself within a few minutes from the moment of exposure to a low temperature and is expressed in the appearance of a rash in areas that are directly in contact with the cold. Most often there is an allergy to cold on the hands and on the face. Sometimes the rash is also manifested on the lips, when a person by forgetfulness has drunk a cold drink forbidden to him.
Allergic rashes whitish or pink for color and itch. Usually these manifestations take place within a few hours. In the event that the body reacts to the cold itself, but to the cold wind, the rashes are usually accompanied not by itching, but by burning. Sometimes the allergic reaction is so severe that after the disappearance of allergic manifestations in the form of a rash, bruises (hematomas) remain in their place. Sometimes, to external manifestations of cold allergy, hypotension (low blood pressure) and headache are attached. Also, due to malnutrition of skin areas that have been exposed to cold exposure, it is possible to develop cold dermatitis, which manifests as flaky and itchy burgundy-red spots.
Below we will consider the most common allergic reactions to cold:
• Labored breathing. This symptom arises from the development of bronchospastic reflex, as a result of which the airways sharply narrow. In the case of an acute reaction to the cold, one can speak of the hyperreactivity of the bronchi and a predisposition to such a serious disease as bronchial asthma
• Hives. This manifestation is characterized by reddened skin, which itches and becomes blistered. Urticaria can develop in the case of contact with cold water or air, but the worst thing for a person is when it's cold and damp at the same time. Most often, rashes occur on the inner side of the popliteal region and thighs, on the feet, hands and skin of the face. To get rid of these manifestations, it is best to go to a dry warm place as quickly as possible, to drink something hot, put on warm dry clothes and take an antihistamine. Totally to save from allergic displays warm clothes can not, however considerably will weaken their display. In this case, you should know that synthetic and woolen things can provoke an allergy, so you should choose the outer clothing of linen or cotton cloth
• Migraine. During the cold, many people have a headache and freezing jaws, this is a cold migraine . In case of ignoring this symptomatology, the development of such a serious disease as trigeminal neuralgia
• Runny nose or pseudoallergic rhinitis. This condition develops under the influence of cold air. It can be saved from it, burying special drops before going to the cold, but it should not be misused, since the mucous
• Radiculitis. This disease develops in the case of inflammation of the roots of the spinal cord, which can develop under the influence of the immune complexes formed in the cold. In order to prevent this, it is necessary to dress more warmly, and in case of an already occurring hypothermia it is necessary to warm up with the help of hot tea and taking a warm bath in the shortest possible time. It is recommended to grind the loin of warming ointment
• Pseudoallergic conjunctivitis. This condition is characterized by lachrymation, redness of the eyes and itching, which in the case of a person falling into a warm place almost immediately disappear. In case of periodic development of such symptoms, contact lenses and makeup for the eyes before going out to the cold, it is not recommended to use, as this can provoke the development of already present conjunctivitis
The most informative method of diagnosing a person's cold allergy is a test with a piece of ice, during which a small piece of ice is applied to the skin for fifteen minutes. In case if there is an itch, reddening and / or blisters after the skin, the test is considered positive. It should be noted that in the case of family cold urticaria, this test also gives a positive result, but the characteristic manifestations appear only after a few hours
Allergy to cold - treatment
Unfortunately, there is currently no specific effective treatment for cold allergy. All existing medicines remove exclusively manifested symptoms, and the disease itself can not be cured. In addition, the vast majority of antihistamines have many side effects (kidneys, liver, metabolic processes, nervous system) and that perhaps the most unpleasant thing is that they get very addictive. However, if you still can not do without them, then they should be taken in minimum doses. Before going out, taking antihistamines (Telfast, etc.) will prevent allergy symptoms in the cold.
Often, cold allergy is not an independent disease, but a symptom of some other serious pathology, therefore, in case of this allergic reaction, to identify depleting immune system diseases should be carefully examined. If you are allergic to cold, contact with any possible allergens should be avoided whenever possible.
Some people mistakenly think that a good preventive remedy for this type of allergy is the use before entering the street of strong spirits. This is a serious and dangerous delusion! In fact, alcoholic drinks not only do not have a beneficial effect with cold allergy, but also contribute to the aggravation of the process.
