What is the reason why small red spots appear on children’s faces when they get hot?

Because living conditions are better now, almost every family lives in a spacious and bright house. However, because of the heating in the north, many newly built houses are very hot in spring, summer, autumn and winter, which brings trouble to the babies at home. Many parents have found that small red spots appear on their children's faces in a relatively hot environment. What kind of disease is this? It may be a problem of eczema or prickly heat.

Infant eczema, also known as "milk rash", is an allergic skin inflammation caused by a variety of internal and external factors. It is one of the most common skin diseases in infancy. The skin lesions are polymorphic lesions mainly composed of papules and herpes, with a tendency to exudate, recurrent attacks, overlapping acute and chronic phases, accompanied by severe itching, and the cause is often difficult to determine. The disease has no obvious seasonality, but it often relapses in winter and can be generalized or localized, so eczema affects the patient's daily life and skin.

Difference between prickly heat and eczema

As summer arrives and the weather gradually gets hotter, babies are more likely to get prickly heat. For many new parents, it is still difficult to correctly distinguish between prickly heat and eczema. What are the differences between prickly heat and eczema? There are still big differences between prickly heat and eczema, which can be distinguished by the causes, seasons, locations and symptoms of prickly heat and eczema.

Prickly heat is caused by blocked sweat pores, while there are many causes of eczema, which are often unstable. Common causes of eczema include: eating certain meats such as fish, shrimp, eggs, beef, mutton, etc.; inhaling certain pollen such as dust mites, wool, etc.; focal infections such as tonsillitis; sunlight, heat, dryness, etc. in the living environment; chemical substances such as cosmetics, soap, etc.; indigestion, gastric dysfunction, and abnormal metabolism of new products, etc. It can be seen that prickly heat is a temporary disease, while eczema is a chronic disease.

2. Different seasons of occurrence

Prickly heat occurs in summer and is more common in children. Eczema is not seasonal and can occur all year round, regardless of gender, age or age. However, it often relapses or worsens in winter, has a tendency to exudate, a chronic course, and is prone to repeated attacks.

3. Different locations of occurrence

Prickly heat often appears on the neck, chest, back, elbows, popliteal fossa and other parts of the body. In children, it may occur on the head, forehead and other sweaty areas. Eczema can occur anywhere, but often occurs on the cheeks and forehead.
