Heat rash, also known as prickly heat or miliaria, is a common skin condition that occurs when sweat ducts become blocked and sweat is unable to escape the skin. It typically appears as a rash of small, red bumps on the skin and is often accompanied by itching and a prickling sensation. Heat rash is most common in hot, humid weather and is most often seen in infants and young children, but it can affect people of any age.

Symptoms of heat rash

The primary symptom of heat rash is a rash of small, red bumps on the skin. These bumps may be accompanied by itching and a prickling sensation. The rash is often found in areas where sweat tends to accumulate, such as the neck, chest, and folds of the skin.

Other symptoms of heat rash may include:

• Redness and swelling of the skin
• A feeling of warmth or heat in the affected area
• Itching and a prickling sensation
• Blisters or pustules
• Dry, flaky skin

Heat rash can also cause discomfort and irritation, leading to difficulty sleeping and a general feeling of discomfort.

Treatment for heat rash

The most effective treatment for heat rash is to move to a cooler, less humid environment and allow the affected skin to air out. It is also important to keep the affected area clean and dry to prevent further irritation.

Over-the-counter creams and ointments, such as calamine lotion or hydrocortisone cream, can be applied to the affected area to help soothe itching and reduce inflammation. Avoid using creams and ointments that contain fragrances or alcohol, as these can further irritate the skin.

In severe cases, oral antihistamines or prescription creams may be necessary to control symptoms. It is important to follow the instructions of a healthcare provider when using these medications.

Prevention of heat rash

To prevent heat rash, it is important to take steps to stay cool and dry in hot, humid weather. Some ways to do this include:

• Wearing loose, lightweight clothing made of natural fibers such as cotton
• Using air conditioning or fans to keep the air cool and circulating
• Avoiding heavy exercise or activities that cause excessive sweating
• Keeping the skin clean and dry, particularly in areas prone to sweat accumulation
• Using antiperspirants or deodorants to reduce sweating

It is also important to drink plenty of fluids to stay hydrated, as this can help to reduce the risk of heat rash.
