Miliaria (Prickly Heat) is a small red and prominent rash that itches, and can cause a stinging or sore sensation on the skin.
This disorder, also known as a hot rash, does not only occur in infants, but adults can also experience it when the weather is hot or in a humid temperature environment.
Prickly heat usually appears a few days after a person is exposed to hot temperatures.
This condition can appear in all parts of the body, but often appears on the face, neck, back, chest and thighs.
Types of prickly heat and symptoms
The location of the appearance of a rash in adults and infants is generally different. In infants, prickly heat usually appears on the neck, and sometimes on the armpits, elbow folds and groin.
In adults, prickly heat will appear on the folds of the skin rubbing against the clothes. There are several types of prickly heat according to their severity.
The signs and symptoms that appear also vary in each type. The following are known types, namely:
- Miliaria crystalina.
This is the lightest type of prickly heat and only affects the sweat ducts of the top skin layer.
This condition can be marked by the appearance of pimples filled with clear liquid that is easily broken.
Miliaria crystalina is more likely to occur in infants than adults. This type of sweat is usually not itchy and doesn't hurt.
- Miliaria rubra.
This type of sweat arises in the deeper layers of the skin and usually occurs in areas with hot or humid temperatures.
The symptoms of this condition are an itching and stinging sensation accompanied by the appearance of a red nodule.
The skin will experience inflammation and pain due to sweat that cannot come out from the surface of the skin.
- Miliaria pustulosa.
This is the development of miliaria rubra where the nodule is inflamed and filled with pus.
- Miliaria profunda.
This is the type of prickly heat that occurs most rarely, and affects the dermis or the deeper layers of the skin.
This type of prickly heat can be chronic and often recur. This condition is more likely to occur in adults after physical activity that produces a lot of sweat.
The signs seen from the miliaria profunda are red nodules that are bigger and harder.
Prickly heat is generally not a condition that requires special handling.
This condition can usually heal itself by cooling the skin and avoiding heat exposure.
However, see a doctor immediately if the rash appears to be getting worse, the symptoms that appear last long enough, or you see signs of infection, such as:
- Fever and chills.
- The pain increases.
- Pus comes out of a pimple and a rash lump.
- Swelling of lymph nodes in the armpits and groin.
Risk of prickly heat and its causes
Prickly heat is caused by sweat trapped behind the skin and cannot evaporate due to the body's sweat glands being blocked.
As a result, the skin becomes inflamed and a rash develops. The following are some factors that can inhibit sweat glands in the body, namely:
- Tropical climate.
The appearance of prickly heat can be caused by weather or the temperature of a hot and humid environment.
For example because of using clothes that are too thick or sleeping with excessive blankets.
- Certain physical activities.
Sports or work that requires heavy physical activity to cause a lot of sweat can also cause prickly heat.
- Sweat glands have not developed.
Cases of prickly heat are easier for babies, especially in infants who are warmed up with an incubator, wear hot clothes, or have a fever.
The baby does not yet have sweat glands that have fully developed and can sometimes make sweat hold behind the skin.
- Bed rest too long.
- The risk of experiencing prickly heat is also high in patients who are required to rest in bed for quite a long time.
Prevention of prickly heat
There are several steps that can be taken to prevent prickly heat, namely:
1. Try to keep the body from overheating, especially in the summer.
2. Use soap that does not make the skin dry and does not contain perfume.
3. Do not use lotions or creams that can clog the skin pores.
3. Avoid wearing tight clothing that can cause skin to breathe hard. Okay, thank you...
