Causes of heat prickly heat

The weather is getting hotter and the complaints about prickly heat among parents are increasing. So, do you know what causes heat rash?

Why do you have prickly heat

In the environment, the temperature is high and the humidity is high. Excessive sweating is not easy to evaporate. Sweat causes the child's cuticle to soaking, causing the sweat glands to be blocked up, and sweat can not be drained away in the lumen, thus breaking through the sweat gland catheter and stimulating the skin tissue. * so all kinds of symptoms come out.

Prickly heat in daily care

When the ambient temperature drops, prickly heat often subsides by itself. Therefore, when children have prickly heat, parents can appropriately lower the air conditioning temperature; Some parents think that since the temperature is so high, it's better not to wear clothes. In fact, loose, sweat absorbing cotton clothes are more conducive to sweat discharge; You can gently wipe the skin with a soft towel when taking a bath to help the skin properly peel off the stratum corneum and help the sweat duct recover smoothly; Powdered prickly heat powder composed of talc powder may cause adverse reactions in the baby's lungs after inhalation, but parents can use liquid prickly heat powder and calamine lotion to keep the local skin dry and lubricated; For children with recurrent red prickly heat, doctors will appropriately give weak hormone ointment to help control inflammation.

Symptoms of prickly heat

According to the different parts of sweat gland duct injury and sweat overflow, prickly heat can be divided into the following types, and the symptoms are different:

1. Red prickly heat

Symptom overview: red spots and papules with scattered distribution, extreme itching and tingling, burning or tingling sensation. Large blisters or pustules with needle cap can be seen at the top, and the skin lesions will fuse. Exposure to a hot environment for several days to several weeks, usually occurs in the parts of indirect friction, such as the anterior cubital fossa, popliteal fossa, trunk, abdomen and groin.

Symptom interpretation: generally, the onset is relatively urgent, and it is the most common prickly heat of the baby.

2. Prickly heat

Symptom overview: small, clear, very superficial and non-inflammatory blisters. White prickles may occur when sweating increases due to fever or clothing hinders the release of heat and moisture, such as a baby who is often wrapped.

Symptom interpretation: the rash is asymptomatic, and it is easy to break with slight friction. Therefore, it exists for a short time, which is a relatively mild prickly heat.

3. Purulent prickly heat

Prickly heat: it is usually caused by the development of purulent sweat and other symptoms. Pustules are obvious, superficial and separated from hair follicles. Pruritus pustules are most common in the rubbing area, the curved sides of the limbs, the scrotum and the back of bedridden children.

Symptom interpretation: purulent prickly heat is the highest symptom level among prickly heat, which is difficult to recover. Mothers should pay attention to protecting the dryness of baby's skin and indoor ventilation.
