With the onset of hot and humid weather, many people, especially children, experience a rash that feels like tiny pricks on the skin, often referred to as prickly heat or heat rash. It’s common among children and adults alike. The medical term for prickly heat is Miliaria Rubra. This article will cover the causes, symptoms, prevention tips, and treatments for managing heat rash.

What is Prickly Heat?

Prickly heat, also known as sweat rash or heat rash, is a skin condition that occurs when sweat gets trapped beneath the skin due to clogged sweat ducts. It is most common in hot, humid weather when the body produces more sweat than can be efficiently evaporated. While it can affect people of any age, it is especially prevalent in newborns and children due to their more sensitive skin and narrow sweat ducts.

What Causes Prickly Heat?

Prickly heat is triggered by excessive sweating combined with blocked sweat ducts, which prevents sweat from evaporating from the skin. The buildup of sweat leads to irritation and the development of the rash. Several factors can worsen the condition:

• Wearing tight-fitting synthetic clothing that limits airflow and traps sweat.
• Obesity can cause prickly heat in skin folds, where air circulation is poor.
• Bedridden individuals are prone to heat rash due to prolonged contact with the bed, leading to moisture buildup.
• Children and newborns are more susceptible because their sweat glands are underdeveloped and can get clogged easily.
• Bacterial blockage of sweat ducts can also be a cause.

Symptoms of Prickly Heat

Heat rash typically appears a few days after repeated exposure to hot and humid conditions. Common areas affected are body folds like the neck, armpits, groin, and behind the knees, but it can occur anywhere if tight clothing restricts airflow.

The symptoms include:

• Red and swollen skin with tiny red bumps.
• Itchy and prickly sensation.
• The rash may feel prickly, like being poked by small needles.

15 Tips to Ease Prickly Heat

1. Avoid hot and humid weather whenever possible.
2. Stay in air-conditioned rooms during the hottest parts of the day.
3. Take cool baths to soothe itchy and irritated skin.
4. Wear loose-fitting cotton clothes that allow proper air circulation.
5. Avoid overdressing newborns; dress them lightly.
6. If bedridden, change the posture of the individual regularly to prevent rash.
7. For obese individuals, ensure that skin folds stay dry and pull apart the folds to let air in.
8. Apply calamine lotion to soothe the skin and reduce itching.
9. Use cool compresses by dipping a cloth in cold water and applying it to the affected area.
10. Frequent showers with cold water using mild, fragrance-free cleansers can help.
11. Let your skin air dry instead of toweling off after a bath.
12. Avoid using creams or ointments that may clog the sweat pores.
13. Stay hydrated by drinking 2-3 liters of water daily to support your body’s natural cooling system.
14. Over-the-counter steroid creams can be used if the rash persists.
15. Avoid strenuous activity in hot weather to prevent further overheating and reduce the risk of heat stroke.

If home remedies and over-the-counter treatments don’t alleviate the rash, you may need to consult a dermatologist. Seek medical help if:

• The rash shows pustules or signs of infection, as you may need an antibiotic prescription.
• You develop a fever, which could indicate either an infection or overheating.
• The rash persists for an extended period despite your efforts to manage it.
