Heat rash - Home remedies for heat rash
Heat rash

Heat rash is a skin disorder that often happens when the weather is hot[1][2]. The disease develops when the sweat ducts are blocked, and sweat is stagnant under the skin. In other words, the trapping of your sweat is one of the main reasons that cause the inflammation and itching around your sweat pores.

Miliaria is another medical term of the heat rash aside from being called prickly heat as well. Such a condition tends to occur mainly after the repeated moments of sweating too much in a hot and moist setting. And the rash probably appears like the clear blisters. In case you don’t know, there are three various kinds of prickly heat, including:

  • Miliaria Crystalline: It’s the mildest type of heat rash, often showing up as the blisters that won’t ever feel itchy or painful at all.
  • Miliaria Rubra: It often occurs deeper into the outer layer of your skin, and feels itchy with many red bumps. This form of prickly heat is commonly found in both infants and adults.
  • Miliaria Profunda: It’s the least common form of heat rash, often in adults and right after continued events of prickly heat and colored lesions.

As usual, heat rash or prickly heat is usually identified by its external appearance, and won’t need the medical attention. In this case, you can freely choose any of the reliable home remedies for heat rash for temporary relief.

However, if you see it not going away after three or four days at all, or when it seems to be getting worse and worse than before, or when you grow a fever, then make sure to contact your doctor at once.

What causes heat rash?

Before learning how to use home remedies for heat rash, let’s get to know more about its real causes:

  • Excessive sweat clogs your skin pores.
  • When your sweat gets trapped under the skin
  • Wear synthetic-fibers clothes
  • Work out too much with high levels of sweat
  • Use oil-based products
  • Put on hot clothes
  • Use certain medicines, for blood pressure or ADHD

The time when you find yourself staying in a warm environment and wearing too many clothes leads you to prickly heat or heat rash. And a hot or warm atmosphere naturally takes on different forms out of your expectations. For instance, a hot summer day and a non-air-conditioned place is the cause of a heat rash.

Or when you try to overheat the entire house during the winter and keep yourself bundled up, it raises the high risk as well. And since you get overheated, he or she will naturally sweat, but not successfully before growing the heat rash. To dodge this, you must find back the balance between what you’re supposed to wear and where you’re going to put it on.

But in general, heat rash is trusted to occur due to the blockage of your sweat ducts and even the follicles of the skin. And it’s the plugged sweat glands with your trapped sweat contribute to the little bumps noticeable in this case.

You must know that our sweat has a high content of salt, which means being a quite potential irritant that might lead to the skin rashes. To stop it, it’s best to wash off the sweat with soap and lukewarm water.   

Risk factors for heat rash

There are said to be many risk factors of heat rash that will cause a particular person to grow the prickly or sore rash. It often starts with an unsatisfied sensation before the reddish and little blisters show up. The itchy feeling will be followed by a prickling condition that reaches the peak once the person gets sweating in the hot times of that day.

As people always thought, the heat might be the leading element why you have to suffer from the heat rash; in fact, we have more reasons than that, and these add more effects to it. They are your age, physical activities, and climate in tropical areas, which will cause a few of us more likely to suffer the condition.

  • Your age: prickly heat will influence people from every walk of life, but infants are the ones more prone to it due to their thin and sensitive complexion. For the older people, they’re also more likely to suffer this condition due to the shortage of their physical movements. It would cause some of their body regions not to gain the right ventilation.
  • Your physical activities: When lacking physical motion, it means that you, especially the older adults will be at risk of dealing with the irritating skin rash. And when having too many of it, you’re led to growing the final prickly rash for sure. It occurs since you sweat too much as a consequence of your intensive activities.
  • Climates: I’m pretty sure that once staying in the countries with tropical climates, then you quickly raise the heat rash risk. If that area owns hot and moist weather the entire year, not just you but also the citizens who live there are more prone to growing the rashes.  
  • Heavy clothes or elements: Stop wearing clothes with heavy materials because they won’t be able to absorb any sweat or can’t offer you sufficient air circulation. And such a thing will add to the whole development of the skin rash condition.
  • The use of medications, creams, and moisturizers: These types of cosmetics can quickly place you at risk since they’re likely to trigger the blockage of your sweat ducts.

Most common symptoms of heat rash

Your pediatrician is the one who will give the complete diagnosis before you decide to use any of our recommended home remedies for heat rash. It’s essential to seek any skin region with an outbreak that has tiny red bumps covered by the redness of your skin. Take a quick look at some noticeable signs of them:  

  • Red/pink rashes or swollen regions of skin
  • Little blisters on some body areas
  • Itchiness and irritation  
  • Shows up in neck, shoulders, neck, chest, armpits, elbow and groin.

As you see, symptoms of heat rashes are the blisters under the skin and tiny red itchy spots in some regions that strongly sweat like back, armpits, abdomen, groin, chest, forehead, elbow folds, under the breasts, buttocks, neck[3]… They may cause prickle and discomforts.

Meanwhile, if in infants, you might detect the heat rash on the neck, chest, and shoulder. Besides, such a condition gets often accompanied by the pins-and-needles feeling, so ensure to watch out for some scratching as well.

But note that the severe heat rash tends to feature a higher degree of discomfort and big welts as well as enhanced red bumps. In other words, you will see a few people with heat rash feel quite itchy while some others might have no irritating sign.

Typically, heat rash can heal itself, but some severe causes need the proper treatment. The best method to repel the symptoms is to cool the skin and anti-perspiring.

Heat rash affects mainly in children, but the disease can occur in 1/3 of adults living in the tropics and can affect everyone in the hot and moist climate.
