What are thermal hives?
Thermal hives, which are also known as cholinergic urticaria, are hives that occur as a reaction to an increase in body temperature. The hives usually appear as small red bumps, usually the size of a mosquito bites. The rash can be in patch or all over the body. Sometimes, if the rash persists, the bumps can connect to the formation of large irritated areas of the skin. The exact cause of the condition is not fully understood, but some research has led to the conclusion that people suffering from this condition can have an allergic reaction to their own sweat. In some cases, the hives may cause itching or sting. In serious cases, some people may also have difficulty breathing and experience a reduction in blood pressure. In some individuals, the appearance of this type of rash is considered to be a trigger of asthma attacks. Topplota dy in normal range. For example, they should probably exercise in an air -conditioned room and keep a lot of cold liquids at hand to prevent their body temperature from preventing the climb. In the showerThe water temperature should be cold or warm. If the heat exposure is inevitable, people who suffer from thermal hives should be sure that they are appropriately dressed. Ideally, under these circumstances, the clothes should be free and designed for hot weather.
In some cases, thermal hives may also be caused by stress, anger and depression. Because emotions generally do not cause sweat, the connection between emotional reaction and thermal hives is unclear. One of the reasons why research has not led to the definitive cause of heat -related hives may be that triggers may vary significantly for the condition.
To diagnose thermal hives, doctors usually perform a skin allergy test. This is done by applying a chemical called methacholin to a small area of the skin. It is believed that methacholin duplicates an allergic reaction that people usually have to heat. Although this type of TES isTypical, the results are accurate about 33% of the time.
treatment for people suffering from thermal hives usually consists of antihistamines or steroids. Antihistamine is a type of allergic drug that inhibits the production of chemicals called histamine, which is assumed to be responsible for allergic reactions. Treatment of steroids is usually reserved for chronic conditions or for those who experience some of the more serious symptoms associated with thermal hives.
