30 Second Summary

  • Rash is a skin condition that occurs when the skin is exposed to hot and humid environments.
  • A rash can cause redness, swelling and blisters on the skin.
  • Rash is usually more common in infants and children.
  • The rash usually goes away on its own, but severe cases may require medical intervention.

What isrash (Miliaria)?

Although it is usually associated with babies, rash is a skin disease that can be seen in people of all ages. Rash, which is usually seen in the summer months when the temperature and humidity are high, is one of the common skin diseases in the society.

Miliaria also called rash, causes pink or red bumps on the skin. Although similar to the symptoms of a rash, rash is not a disease to worry about. In addition to being generally seen on the shoulders, back, arms, chest, legs and abdomen, it is especially concentrated in the curved parts of the body.

Rash is caused by the body's reaction by sweating when the external environment is too hot and humid. Since both sweat and external factors cause clogging of the pores on the skin, there is also a closure of the sweat ducts. This cycle causes the rash to develop.

The reason why babies and children have rashes more often than adults is that their sweat glands are underdeveloped and their skin pores are smaller. In addition, the fact that parents do not dress babies and children in accordance with the temperature is among the main reasons why diarrhea is more common in babies and children.

The main cause of diaper rash in adults is excessive sweating but not enough showering. In addition, women not changing their pads frequently enough during menstrual periods and not using cotton underwear are among the main causes of diaper rash in adults.

Diagnostic methods for rash (Miliaria)

No special tests are needed to diagnose rash. Rash, which is usually characterized by its appearance, can be diagnosed by physical examination by physicians. In addition, doctors may order tests to rule out other diseases.

Causes ofRash (Miliaria)

Rash is more common especially in people with fair skin color. In addition, the following are among the causes of diaper rash.

  • Sweating due to heat
  • Febrile illnesses
  • Babies have sensitive skin
  • Dressing babies and children too thickly
  • Tight and synthetic clothing
  • Not changing diapers frequently enough

How to prevent a rash?

Although diaper rash is a condition that usually does not require treatment and resolves spontaneously within 3 to 4 days, it can be especially disturbing in infants and children. For this reason, its prevention, especially during the hot summer months, makes children more comfortable.

Among the measures to be taken for rash are the following:

  • It is especially important to keep the skin cold to prevent rashes. For this, it is necessary to shower regularly and use warm water during the shower.
  • It is important that the products or cosmetics used in skin care are free from ingredients that cause clogging of the pores on the skin. If there are products with this feature, it is recommended not to use them in summer.
  • As underwear, options made from natural fibers such as cotton should be evaluated. On hot days, tight and dark-colored clothes should be avoided. Otherwise, it becomes difficult for the skin to breathe and an environment is created for the rash to develop.
  • Do not stay in hot and humid environments for long periods of time.
  • Bedrooms need to be constantly ventilated.
  • It should be ensured that the duvet covers are made of natural yarn. Sweating while sleeping should be prevented.
  • Babies should not be overdressed.

Types of rash

There are 4 different types of rash caused by the closure of sweat ducts.

Milaria crystallina

In milaria crystallina, a mild type of rash, there is a blockage of the pores in the epidermis, the upper surface of the skin. As a result of the superficial closure of the pores, the skin shows the presence of scaling with a diameter of 1 to 2 mm and the appearance of a water sac. Water bladders look like water balls or dewdrops and can burst easily. In addition, the water sacs are filled with clear liquid. This type of rash does not cause pain or itching and usually occurs in babies.

Miliaria rubra

In the miliaria rubra type, which is caused by blockage of the sweat glands at the bottom of the epidermis layer, small vesicles in pink tones close to red are seen on the skin. It is also possible to see vesicles as needle-tipped or conical papules. Usually seen on the arms and legs, miliaria rubra causes burning and itching.

Miliaria profunda

The most characteristic symptom of the miliaria profunda type, which is caused by blockage of the sweat glands located in the middle layer of the skin, is the stinging sensation. It causes the formation of swellings that are close to red in color, which cause discomfort to people and appear on the skin surface. A rare form of rash, miliaria profunda is more common in adults because it is usually caused by sweating during physical activity.

Miliaria pustulosa

This type of rash, accompanied by an inflammatory bacterial infection, causes the formation of pustules on the skin surface. It can manifest itself with pus-filled blisters or as pus filling under the skin.
