As pointed out by the specialists of the Spanish Society of Allergology and Clinical Immunology (SEAIC) [1] cold urticaria is a type of physical urticaria, which manifests itself mainly as a skin reaction that arises in direct contact with the cold.

Low temperatures, a gust of icy wind, a full bath or immersing a part of the body in cold water, contact with a ‘frozen' object or even the intake of very cold drinks or food could trigger it.

If you ask yourself “Why do I have an allergy to cold?”, pay attention to the causes of hives, which can be very diverse:

  • Excessive skin sensitivity or other disorders that affect the skin.
  • Intolerance to cold.
  • Allergic reactions.
  • Hereditary factors.
  • The alteration in the immunoglobulins present in the blood, which could be behind the episodes of cold urticaria, which usually occur mainly in young adults.

Symptoms of cold urticaria

The cold is what triggers the symptoms of hives, the most common being the appearance of reddish welts or hives accompanied by an intense r peak, characteristic of any type of urticaria. In addition, it is common for swollen areas to appear to a lesser or greater degree.

How do you know if you have an allergy to cold? Pay attention to the following symptoms, which may be located in the area of skin most exposed to cold. For example, swelling in the lips if you have taken an ice cream, in your hands, if you have held a cold object or in specific areas of the face if you have been exposed to an icy wind.

In the most severe cases, the symptoms can spread to the whole organism causing serious manifestations, such as swelling of the tongue and throat or even tachycardia or lowering of blood pressure, in which case it will be necessary to receive medical assistance immediately.

Except for these exceptions, in general the symptoms of cold urticaria are mild, itching coupled with a slight redness and possible swelling of areas of the skin.

How to tell if you have a cold allergy

If you have doubts about whether you suffer from it or not, the ‘ice cube test‘ can give you the answer. It is a simple test but should always be performed by an allergist to correctly interpret its results avoiding, in addition, any risk.

It consists of applying an ice on the forearm for about five minutes and, after ten, observing any possible adverse reaction in the area.

How long the symptoms of hives last

They appear immediately after contact with the cold and usually disappear, spontaneously, after between 30 minutes and two hours after that contact. This is an important detail when it comes to recognizing a cold urticaria, which has nothing to do with other skin alterations, which can cause low temperatures such as excessive dryness in the skin or the presence of chilblains.

Given its main symptoms, it is important to consult with a specialist doctor to correctly identify the ailment and, if necessary, establish the corresponding treatment.

How to cure cold urticaria

Now, how is hives cured by cold? Preventive measures are the best tool to combat this type of reaction avoiding risk situations. Therefore, pay attention to the following tips to cure hives:
