What are the reasons for the appearance of a negative reaction?
The nature of a sharp reaction of the body to the impactcold is still not known to the end, and medicine does not have generally accepted criteria for setting such a diagnosis. There is an opinion that tissues are locally cooled by exposure to cold air, with damage to the cell walls. As a result, the accumulation of specific proteins - cryoglobulins, which give rise to an allergic reaction, manifested by reddening of the skin, its dryness, pricking and itching. If you stay in the frost for a long time, you may have swelling and blisters, and in the worst case, swelling of the nasopharynx (Quincke's edema). But in a warm place a person's condition improves dramatically, although with a rapid change of temperature (from low to high), active evaporation from the surface of the skin of moisture occurs. As a result, the skin of the face (and brushes, if you did not protect them with gloves or mittens) becomes more sensitive and dry, begins to peel off, cracks appear on it. As a result, it turns out to be a desperate situation: in the cold, the skin suffers, and in the warmth it is not very good. It is believed that cold allergies can be caused by chronic foci of diseases (tonsillitis, caries), the use of certain medications (for example, antibiotics), but the genetic predisposition of such a reaction to the cold is not ruled out. Note that cold allergies can suffer not only the face, but also other areas of the body that are not covered by clothing (wrists, wrists, neck, etc.). 
Who is most susceptible to cold allergy?
Like absolutely all diseases, a cold allergyhas its own "risk group", which most often suffers from this ailment. The most susceptible to a bad reaction to cold: Women. Yes, the weak sex here is really weaker compared to men. The fact is that ladies' skin is thinner than men's, and accordingly, it is more prone to unpleasant influence of physical factors. People who have a dry type of skin. This applies to both men and women. People with this type of skin have a lower production of sebaceous glands of sebum, which is a natural barrier against frost.
What symptoms will help to recognize the ailment?
Conditionally cold allergy can be divided, depending on the degree of manifestation, into two forms:
- Cold dermatitis - involves peeling, redness and itching of the skin.
- Cold urticaria is a more severe form of an allergic reaction, causing the appearance of itchy blisters similar to those that remain after a nettle burn.
Even with a slight drop in temperature,skin may show symptoms of allergies. They disappear after a few hours. Paradox, but for a completely healthy person who has never suffered from allergies, hives can develop. This disease in some cases can occur and at positive temperatures, but in the presence of strong wind and high humidity. The most sad is the fact that if the causative factor (unfavorable climate conditions) is maintained, the disease can develop.
We carry out the cold test
To check if you are prone to cold allergiesor not, you can conduct a simple test. Attach an ice cube to your hand for 5-8 minutes. If at this point the skin starts to itch, blush or it will be burned, therefore, you have a predisposition to this disease.
How to treat cold allergies
So, if walking in the winteryou on the skin appear red spots or other symptoms of the disease, which tend to aggravate, then the best solution to the problem will be a referral to an allergist.

Use of cosmetics Every evening before going to bed apply moisturizing nourishing cream on your face, and not later than half an hour before going outside, apply a thin layer of protective (but by no means moisturizing) cream to your face and hands (preferably on the basis of natural oils) - so you will partially protect your skin from the effects of cold. Blot excess cream with a napkin. Daily diet adjustments Your diet should contain products rich in omega-3 unsaturated fatty acids (these are seafood, various vegetable oils). Or, alternatively, take fish oil for three weeks, one capsule 1-2 times a day. Use of medicines.
