In summer, there are blisters on my hands, which are particularly itchy. What happened?

At present, according to the information provided by the subjects, it is really difficult to judge what skin disease it is, but according to this unique feature, it can be considered as herpes simplex. Personally, I am not a dermatologist, but I have had this kind of herpes on my hands before. I went to see a dermatologist and said it was herpes simplex.

In reality, many people have this kind of herpes, which is easy to appear every summer. It itches so much that I can't help scratching. Although it is not fatal, it is uncomfortable. Today I want to share the knowledge about herpes simplex.

1. What is herpes simplex that easily appears in summer? In fact, herpes zoster is an allergic disease in essence, and most of these patients are allergic, which is also considered as a kind of eczema in clinic. The blister of herpes zoster is more characteristic, slightly higher than the skin surface, mainly characterized by severe itching, which is particularly easy to recur.

The main predilection site of herpes zoster is limbs, which are often symmetrically distributed. Blisters vary in size, as small as rice grains. If the liquid in the blister is not broken, it can be absorbed by itself, which usually takes about 7 days. After absorption, the skin outside the blister will fall off. After opening, you can see the red tissue inside, and there is obvious pain at this time.

From the name of herpes simplex, we can see several characteristics of this skin disease. First of all, such people are prone to sweating, and it is easier to sweat in summer than in other seasons. Therefore, herpes zoster tends to attack mainly in summer. When the weather is getting cold, it can be cured or relieved naturally because of reduced sweating.

Many friends are worried that this skin disease will be contagious, but it is totally unnecessary, because as mentioned above, herpes zoster is an allergic disease in essence, and there is no possibility of infection.

2. What are the factors related to herpes zoster? Although it is an allergic disease in essence, it is meaningless to explain it simply by allergies. At present, the specific pathogenesis of the disease is not clear, but it may be related to mental factors, increased sweating, infection, allergens and so on.

Take mental factors as an example. Many people are in a tense and depressed environment all the year round, which will make the human body secrete a lot of histamine substances. You should know that allergies have a lot to do with this substance. Although it doesn't mean that 100% has herpes simplex due to stress, mental factors increase the incidence of this disease. I believe that in reality, there must be some patients who are in a bad mood and are particularly prone to herpes simplex.
