updated: 11/27/2019

Heat rash is a skin problem that is also as famous as sweat rash or prickly heat. Medically known as miliaria, heat rash is common at all age groups, from adults to babies, in summer because of the heat and humidity. Particularly, children and babies tend to suffer from this condition due to their soft skin. Heat rash may occur when the sweat glands are clogged or blocked due to the sweat. Before getting to know natural and effective remedies for heat rash, you should learn some basics about this condition.

What Is Heat Rash?

In fact, there are several types of skin rashes, and the most common type is heat rash. It makes the patient uncomfortable and painful. This condition usually happens in humid weather conditions. When the sweat cannot escape from your pores, heat rash occurs.

Adults often suffer from heat rash in the rubbing body parts together, such as under the arms or between inner thighs. Babies tend to develop heat rash on neck and skin folds such as elbows, armpits, and thighs.

What Are Causes Of Heat Rash?

This condition tends to happen in warm months and after intense, prolonged workouts. Heat rash happens when the sweat is trapped in the pores. Instead of evaporating, perspiration is trapped beneath your skin, which causes inflammation and rash. Certain types of clothing also trap your sweat, which may result in heat rash. Or, in some cases, using thick creams and lotions could also trigger heat rash. Babies are more likely to get heat rash due to their immature sweat ducts.

  • Prolonged bed rest: This condition may also occur in those who are confined to rest for long periods, particularly when they have a fever.
  • Overheating: Sleeping under your electric blanket or dressing too warmly may result in heat rash.

Food allergy: Babies might be allergic to some foods, powdered milk, milk, breast milk, or the mothers’ food reactions and allergies.  In that case, you should consult a physician immediately for other suitable alternatives.

What Are Heat Rash Symptoms?

Symptoms are small red bumps, also called papules, which cause itching and prickling sensation[1]. They may appear in various body parts at the same time.

The most common body parts for heat rash to develop are the neck, face, under the scrotum, and under the breasts. It may also occur in skin folds and in areas of the body parts rubbing against clothing, such as the chest, back, and stomach. These places tend to sweat more frequently.

Folliculitis, a related condition, may occur at the same time. This happens when hair follicles are clogged with foreign matter, like sebum and dead skin cells. Then, it may be infected, causing inflammation.

How Is Heat Rash Diagnosed And When To See A Doctor?

Doctors often use the physical examination to diagnose heat rash. Knowing that the heat rash appears during heat or sweating, appreciating the position on the body (where clothing fits tightly or in skin folds) and seeing what the heat rash looks like may be enough to diagnose. As with many types of rash, a healthcare professional may take a look at the affected skin and immediately make the diagnosis thanks to previous experience. However, if the rash does not disappear after 3-4 days, or if it gets worse, or if your baby has a fever, contact your doctor instantly.

When babies develop a rash, make sure that you watch for the signs and symptoms of infection, such as:

  • Increased swelling, pain, redness, or warmth around the infected areas
  • Red streaks that extend from the affected areas
  • Pus drainage from the affected areas
  • Swollen, red lymph nodes in the armpit, neck, and groins
  • Fever of 38°C or higher, or chills without apparent reasons.
