If you are searching for the best treatments for heat rash, then this is certainly the best post you need to read. Heat rash is known with its different names, such as prickly heat and miliaria. This annoying skin problem doesn’t only affect babies but also disturbs adults in hot or humid weather. The skin issue develops when the blocked pores trap sweat under your skin. You may experience superficial blisters to deep and red lumps as a symptom of the disease. They are often intensely itchy and can feel prickly. 

Heat rash skin issues can be cured on its own. However, severe forms of heat rash may need medical assistance. In summers, you can keep this annoying skin condition at bay by staying in cool and dry places and preventing sweating. This post elaborates on the causes, symptoms, and best treatments for heat rash. 

Types of Heat Rash

There are several types of prickly heat conditions based on how deep the blocked sweat dusts are. Besides, they show different signs and symptoms. Check the below-given list: 

  • The mildest form of this skin condition is when the sweat dusts are trapped in the top layer of the skin. In this form, you will see clear, fluid-filled blisters and bumps that break easily. 
  • Prickly heat is another form of heat rash that occurs in the deeper layer of the skin. In this type, you will experience red bumps and itching or pricking in the affected area. 
  • Sometimes, the fluid contains miliaria rubra and turns puss-filled and inflammable. It is termed as miliaria pustulosa. Treatments of heat rash in this condition are not difficult. 
  • Finally, a rare form of heat rash can affect the deeper layer of the skin dermis. It is caused due to the retaining of the sweat leaks out of the sweat glands into the skin. It may cause firm, flesh-colored lesions that look similar to goosebumps. 


The symptoms of the heat rash may vary from children to adults. In infants, the rash usually occurs on the neck, shoulder, and chest. Besides, it may also grow in armpits, elbow creases, and groin areas. Contrarily, adults get heat rash in those areas where clothing causes more friction.

Partially developed sweat ducts can rupture more easily, trapping sweat beneath the skin. Heat rash can come into being in infants in the very first week. They become more prone to it when being warmed in an incubator, dressed too warmly, or in case of fever.  

Tropical Climates

Several climatic conditions, such as hot or humid weather, can give rise to heat rash.

Physical Activities

People involved in intense workouts or exercises that can cause heavy sweat may develop a heat rash. After such activities, the best treatment for heat rash is to keep yourself in cool conditions. 


Various conditions that can cause overheating, such as dressing too warmly or sleeping under the blanket, can also trigger heat rash. 

Prolonged Bed Rest

The prolonged bed rest is one of the most apparent reasons behind the heat rash. People who are confined to bed for a long time period are more susceptible to develop heat rash.
