Prickly heat, also known as heat rash or miliaria, is a common skin condition that occurs when sweat gets trapped in the sweat ducts, leading to various discomforting symptoms. In this article, we will provide a simplified explanation of prickly heat, its types, causes, symptoms, diagnostic tests, treatments, and common drugs used for relief.
Prickly heat is a skin condition that happens when sweat gets stuck in your skin’s sweat ducts. It usually occurs in hot and humid weather when you sweat a lot.
Types of Prickly Heat:
There are three main types of prickly heat:
- Miliaria Crystallina: This is the mildest form, where the sweat ducts near the skin’s surface get blocked, causing tiny, clear blisters that burst easily.
- Miliaria Rubra: This type affects deeper sweat ducts, leading to red bumps and intense itching. It’s the most common form of prickly heat.
- Miliaria Profunda: This is the least common type and occurs when the sweat ducts become so clogged that they rupture. It causes flesh-colored bumps and is often painless.
Causes of Prickly Heat:
- Hot and Humid Weather: Prickly heat is most common during summer when the weather is hot and sticky.
- Sweating Excessively: If you sweat excessively, the sweat can get trapped in your sweat ducts.
- Blocked Pores: Sometimes, your skin’s pores can get blocked, preventing sweat from escaping.
- Tight Clothing: Wearing tight-fitting clothes can trap sweat against your skin.
- Physical Activity: Engaging in strenuous activities that make you sweat can increase your risk.
- Overheating: Overheating your body, such as staying in a hot tub for too long, can lead to prickly heat.
- Babies: Babies are prone to prickly heat because their sweat ducts are not fully developed.
- Bedridden Patients: Patients who are confined to bed for long periods may develop prickly heat.
- Certain Medications: Some medications can increase the likelihood of developing prickly heat as a side effect.
- Immature Sweat Ducts: In some cases, sweat ducts may not be fully mature, making them more prone to blockage.
