Sweat Allergy: Can You Be Allergic to Your Own Sweat?

Can you be allergic to your own sweat? It may sound like a strange question, but it is actually a valid concern for some people. Sweat allergies can cause a wide range of symptoms, from skin irritation to full-blown anaphylaxis. If you are experiencing unusual symptoms after sweating, it is important to see a doctor and find out if you have a sweat allergy. In this blog post, we will discuss the signs and symptoms of sweat allergies, as well as the treatment options available.

The symptoms of a sweat allergy

Sweat allergy, also known as cholinergic urticaria, is a rare skin condition that results in hives (urticaria) after sweating. The rash usually appears within minutes of sweating and lasts for about 30 minutes. Some people may have a delayed reaction of up to several hours.

The cause of this condition is unknown, but it may be related to the release of histamine and other chemicals from mast cells (a type of white blood cell) when sweat comes in contact with the skin.

Signs and symptoms of a sweat allergy can include:

-Skin rash or irritation near the sweat glands, most commonly on the forehead, scalp, temples, neck, armpits or groin
-Itching, stinging or burning skin where the rash is present
-Redness or swelling of the skin
-Dry skin
-Cracked skin
-Small bumps on the skin that may resemble pimples.

How is it diagnosed

There are a few different ways that doctors can diagnose cholinergic urticaria. The most common way is to ask the patient about their symptoms and then perform a physical examination. Doctors will also typically order a blood test to rule out other conditions with similar symptoms. In some cases, they may also order a skin biopsy.

This involves taking a small sample of skin and then examining it under a microscope. People with cholinergic urticaria typically have an allergic reaction to their own sweat. This can be diagnosed using a simple sweat test.

The doctor will ask the patient to exercise and then monitor their sweat production. If they develop hives in response to sweating, this is a strong indication that they have cholinergic urticaria.

The treatment options

There are a few options available to treat sweat allergy. The most common treatment is avoidance of triggers, drugs that block histamine receptors, and immunotherapy.

Histamine blockers, such as cetirizine (Zyrtec), fexofenadine (Allegra), and levocetirizine (Xyzal), can help relieve symptoms of a sweat allergy. These medications are available over the counter and by prescription.

If avoidance of triggers and histamine blockers don’t relieve your symptoms, your doctor may recommend immunotherapy, which is also known as allergy shots. Immunotherapy involves injecting small amounts of the allergen you’re allergic to. In case you can’t avoid sweating, over-the-counter antihistamines or medications specifically prescribed for sweat allergy treatment may help.

Why does my own sweat make me itch?

Your own sweat can make you itch because it contains salt, which is a compound that can irritate your skin. The eccrine sweat gland is the type of sweat gland that releases salt-containing sweat.

The majority of eccrine sweat is water, but it also contains other compounds such as salt, urea, ammonia, and lactic acid. These compounds are released from the body when you perspire. Eccrine sweat is produced in response to heat, humidity, and exercise. It’s the main type of sweating that occurs in people who are not overweight and who have a normal body temperature.

Can your own sweat cause hives?

Yes, it’s possible for your own sweat to cause hives. Hives are often the result of a food allergy and can be caused by any number of foods. If you suspect that your hives are being caused by something you’re eating, try keeping a food diary to track what you eat and when the hives appear. Once you have a good idea of which foods are causing the problem, cut those foods out of your diet completely. In many cases, simply avoiding the trigger foods will resolve the hives.

What percentage of people have cholinergic urticaria?

It is estimated that about 1-3% of the population suffers from cholinergic urticaria.

Cholinergic urticaria is a rare skin condition that results in the appearance of hives (itchy, red bumps on the skin) after exposure to sweat, heat, or exercise. The cause of cholinergic urticaria is not yet known, but it is thought to be related to the release of histamine by mast cells in response to acetylcholine (a neurotransmitter).

What triggers cholinergic urticaria?

Cholinergic urticaria is triggered by the release of histamine in response to changes in body temperature. It can be triggered by physical activity, taking a hot bath, or eating spicy foods. The resulting rash is characterized by raised bumps and itching. In severe cases, cholinergic urticaria can lead to shortness of breath and difficulty swallowing. There is no cure for cholinergic urticaria, but avoidance of triggers and use of antihistamines can help to manage the condition.

Does sweat burn my skin?

Yes, sweat can actually burn your skin. It all has to do with the fact that sweat is loaded with salt and other minerals. When these come into contact with your skin, they can cause irritation and even damage the outer layer of skin. In some cases, this can lead to a condition called dermatitis neglecta, which is basically when your skin becomes inflamed and irritated from not being properly cared for.

So, if you find that your sweat is burning your skin, it’s important to take care of the affected area right away and make sure you’re keeping up with good hygiene practices.

What cream is best for sweat rash?

There are a number of different creams that can be effective for sweat rash, but one of the most commonly recommended is a topical corticosteroid. This type of cream can help to reduce inflammation and itching and can also provide some relief from discomfort.

It’s important to talk to your doctor or pharmacist before using any new cream, to make sure it’s safe for you and will not interact with any other medications you may be taking. Be sure to follow the instructions on the package carefully, and if you have any questions, don’t hesitate to ask your doctor or pharmacist for advice.


Although it’s rare, some people can be allergic to their own sweat. It may seem strange, but this allergy is actually more common than you might think. If you have a sweating problem and are not sure whether you’re experiencing an allergic reaction, see your doctor for advice. There are treatments available that can help lessen the symptoms of this condition. Thanks for reading!
