Learn How to Treat Heat Rash

Heat rash is also known by other names, including milaria and prickly heat. It is caused by blocked sweat ducts trapping sweat under the skin. This causes blisters or lumps to form, which can be itchy.

Though often seen in babies, anyone can develop heat rash. How to treat heat rash consists of a few basic tips.

Sweating

Controlling the amount of sweat that is produced can help reduce the risk for heat rash and help alleviate symptoms. This can include wearing lightweight “breathable” fabrics, reducing physical activity and staying in cool areas as much as possible.

Areas of the body that have folds of skin such as under the breasts, between the buttocks and any ‘fat rolls’ may be more susceptible to developing heat rash. To treat these areas, wearing clothes that keeps these areas separated or using some type of absorbent material such as cotton gauze can help reduce the amount of sweat buildup in these places. This can prevent and help relieve heat rash in these areas.

Calamine Lotion

Not just for Chicken Pox, calamine lotion can be used to help reduce the itchiness of heat rash.

Topical Corticosteroids

The application of topical corticosteroids can help ease symptoms for patients, but is usually only used in extreme cases of heat rash. If the heat rash is particularly bothersome and nothing else works, this option may be recommended by the physician.

Cleaning

Keeping susceptible or affected areas clean and dry can be helpful. This can included using a cool cloth to wipe away sweat or using alcohol pads, if they do not irritate the already sensitive skin.

Ice Packs

Using cool cloths, ice packs or even packages of frozen peas on affected areas can help relieve symptoms.

Antibiotics

In some cases, antibiotics may be prescribed. This will occur when a bacterial infection develops. The antibiotics can be prescribed in oral or topical form.

Rest

Some people may experience weakness or malaise with their heat rash. For these patients, additional rest may be in order until the heat rash clears up. This can involve anything from just reducing the amount of physical activity to sleeping a little more than usual while the rash heals.

Antihistamines

Antihistamines may be used as a means of addressing the itching heat rash can cause. These will typically come in oral form, like Benadryl or Claritin.

Summary

While there are a number of ways available for how to treat heat rash, it usually will clear up quickly and without the need for much medication or medical intervention. If symptoms persist or get worse, a physician can be consulted by the patient for help and advice.
