Skin rash

Spring is the season when flowers bloom. Although this season is very beautiful, many people with allergies are very afraid of the arrival of spring, because all kinds of pollen will float in the air in spring. If you don’t pay attention, it will cause allergies, which will cause symptoms of skin rashes. However, it is relatively difficult to solve the problem of skin rashes.

Many friends who have skin rashes will also experience itchy skin. If you want to completely solve the problem of skin rashes, you first need to know what factors cause skin rashes. You must know that it is not just allergies that can cause this condition.

In daily life, the following factors are common causes of itchy skin rashes:

1. Mental and emotional instability can also increase sensitivity to itching. Eating too much spicy food, drinking alcohol or coffee can cause skin itching.

2. In addition to many skin diseases causing itching, some systemic diseases can also cause itching. For example, the itching in uremia is related to a certain circulating factor in the body, and obstructive jaundice can cause persistent itching.

3. Peptides are a type of hydrolyzed protein. In allergic skin diseases, bradykinin is believed to be a medium that causes itching and wheals.

4. Environmental and local factors can directly affect the skin's sensitivity to itchy stimulation. If the skin temperature increases slightly, the itchy feeling will increase accordingly. Hot water bathing, high room temperature, warming up by a fire or exercising can all stimulate nerve endings and cause itching. Excessive humidity in the air can lead to dry skin and can also cause itching. This situation is more obvious in the elderly.

5. Prostaglandins and their related substances, human skin inflammatory cells and arachidonic acid metabolites. These substances include prostaglandins, polymorphonuclear leukocyte chemotactic factor, and leukadiene. Studies have found that prostaglandins themselves cannot cause itching, but they can lower the skin's threshold for itching caused by histamine. This makes the itching worse. It remains unclear whether leukocyte chemokines and leukotrienes can enhance itch induced by other inflammatory mediators.

The above-mentioned factors are all the factors that cause skin rashes. If you want to solve your own problem, please first determine the cause of your skin rashes. Only by treating the cause of your disease can you completely solve the skin rashes and restore your original skin appearance.
