Overview

Heat rash (miliaria rubra), also referred to as heat rash, may be a rash of small red bumps caused by blockage of the sweat glands. It is often thanks to high fever, excessive sweating, or being over-bundled. It is commonly seen in hot, humid tropical climates. It can cause discomfort, itching, and, sometimes, stinging or "prickly"-type pain.

Who's at risk?

Heat rash is more common in hot, humid tropical climates. Someone who is new to such an environment is especially vulnerable. Heat rash is often thanks to high fever, excessive sweating, or being over-bundled. It occurs in individuals of all races, although to a lesser degree in Asians. Infants are the foremost commonly affected as they're subject to over-bundling out of concern for warmth loss after birth.

Signs and Symptoms

Heat rash can occur after exposure to hot conditions. There are often many small, red bumps everywhere the body. The bumps of warmth rash usually occur in highest concentration in covered areas where there's tons of friction, like the neck, chest, and body folds. The face, palms, and soles are generally not suffering from prickly heat . The rash can cause intense itching and stinging, which may become worsened by heat. The individual may feel fatigued and become impatient of heat due to little or no sweating at the affected areas.

Self-Care Guidelines

Prevention and treatment of warmth rash contains controlling heat and humidity. Acetaminophen or ibuprofen can help to scale back fever, which may be a causative agent within the development of the rash. Remove any occlusive clothing, limit activity, and seek air con or any cooler environment. Cool compresses can also help with the discomfort. Heat rash usually resolves once people move to a cooler environment. Make sure to drink lots of fluids.

When to Seek Medical Care

The most common complications from prickly heat include secondary infection from scratching and warmth exhaustion.

Although uncommon, infected areas thanks to breaks within the skin caused by scratching may have antibiotic treatment for resolution. Seek care if the rash develops pus, redness, crusting, swelling, or tenderness.

In cases of warmth exhaustion, the skin will appear hot and flushed with none sweat. The person may complain of dizziness, nausea, weakness, headache, confusion, or difficulty breathing. Heat exhaustion can reach heat stroke, so medical aid should be obtained directly . Symptoms of warmth stroke include a really heat of 105°F or greater, decreased or loss of consciousness, or seizure.

While awaiting medical aid , get the affected person indoors or under shade, undress them, and apply cool compresses to the body.

Treatments Your Physician May Prescribe

If there are signs of secondary bacterial skin infection related to the warmth rash or otherwise, oral or topical antibiotics could also be given.

Dehydration may be treated with intravenous fluids, especially if there is vomiting. Heat stroke is treated by trying to quickly reduce the core temperature to normal. Immersion, evaporative, or invasive cooling techniques could also be utilized in addition to rapid administration of intravenous fluids. This type of care is administered within a hospital setting.
