Everyone deals with stress from time to time, and stress can have an effect on more than just your emotional health. Stress can also cause physical symptoms, such as a rash, which can amplify your stress.

Luckily, a stress-induced rash generally isn’t cause for concern. In fact, it can often be treated easily at home.

If you have a preexisting skin condition, such as psoriasis or rosacea, you may also find that stress worsens your symptoms. If this occurs, stress is considered a trigger.

We explain how to identify a stress rash and the best way to treat one.

Stress rashes often take the form of hives, also called wheals or welts. Hives can appear anywhere on the body. Areas affected by hives are generally red, raised, and swollen. These blotchy areas can be as small as a pencil tip or as large as a dinner plate.

Sometimes these patches may connect to form even larger welts. These wheals can range in size from less than a centimeter to big patches covering large areas of the skin.

Hives can also appear as general skin swelling that develops in one place on your body. This section of swelling may disappear and then appear somewhere else.

Areas affected by hives will likely itch. You may also experience a tingling or burning sensation when touching the affected areas.

A single hive generally fades in about 24 hours. But new hives may form as old hives disappear. If you have multiple hives, you may experience these symptoms for about six weeks. This is considered a bout of acute hives.

Though less common, your symptoms may persist beyond six weeks. If this happens, your hives are considered chronic.

Hives are often the result of your immune system reacting to an allergen. Hives can also be caused by other factors, like a viral infection, other illness, or environmental trigger. Stress is considered to be an environmental trigger.

The most common food allergens include:

Other notable allergens are pollen, pet dander, and medications such as penicillin.

Other environmental triggers include:

  • hot and cold temperatures
  • sunlight
  • water
  • exercise

When you’re stressed, it isn’t uncommon to experience a flare-up related to an existing skin condition. This happens because your body releases extra chemicals, like neuropeptides and neurotransmitters, when you’re stressed.

These chemicals can change how your body responds to various functions. This change in response can cause inflammation, sensitivity, and other discomfort to the skin.

Sometimes hives go away on their own without treatment. Otherwise, the condition can generally be treated at home. The most common treatment for hives is an over-the-counter (OTC) antihistamine. Antihistamines can relieve symptoms like itching.

Common OTC antihistamines include:

You may also find relief by using a cool compress on the affected areas. Soaking in a cool bath or taking a cool shower may also help.

If your symptoms worsen or last longer than six weeks, you should consult your doctor. Hives that last beyond six weeks are considered chronic and may or may not go away on their own within a year.

Your doctor may prescribe one of the following to treat severe or chronic hives:

  • prescription-strength antihistamines
  • corticosteroids, like prednisone (Deltasone)
  • antibiotics, like dapsone (Aczone)
  • an injectable type of medication, like omalizumab (Xolair)
  • other medications that fight redness and swelling

If you experience swelling of the lips or face, trouble breathing, or wheezing, you should seek immediate medical attention. These can be life-threatening complications, and you may need an epinephrine shot for treatment.

If your rash is tied to a preexisting condition, such as psoriasis or rosacea, talk with your doctor. They can evaluate your current treatment regimen and may be able to make adjustments if needed.

It’s possible to confuse a stress rash with other common skin conditions. These include:

  • heat rash
  • pityriasis rosea
  • rosacea
  • contact dermatitis
  • eczema

Here’s what you need to know:

Heat rash

If you live or work in hot, humid conditions, you may be experiencing heat rash. This happens when your pores become blocked and sweat is unable to escape.

The most common form of heat rash, miliaria crystallina, causes clear or white bumps. Miliaria rubra can cause small red bumps that itch similar to hives.

Unlike some cases of hives, heat rash almost always clears up on its own. It typically goes away in a few days. Consult your doctor if you begin to experience:

Pityriasis rosea

Pityriasis rosea is a common type of rash that often goes away on its own. It typically starts with a large patch of red, raised skin. This “mother patch” or “herald patch” may be surrounded by small red bumps called “daughter patches” that are typically oval in shape. It’s also sometimes called a Christmas tree rash.

It’s unclear what causes this rash, but it’s most common during the spring and fall. It may or may not be itchy.

Pityriasis rosea typically fades without treatment in six to eight weeks. During this time, you can use an OTC anti-itch medication, like diphenhydramine (Benadryl) or cetirizine (Zyrtec) to ease your symptoms.

If your symptoms worsen or persist, consult your doctor. They may be able to recommend a prescription-strength anti-itch medication.

Rosacea

Rosacea is another common skin condition. Depending on the type, it often causes small, red — sometimes pus-filled — bumps to form on the skin. The skin can thicken in these areas.

The rash typically covers the cheeks, nose, and forehead, but it can involve other areas of the face. These bumps may appear for weeks to months before disappearing and appearing again at a later time.

Although rosacea can affect anyone, it’s most common in middle-aged women who have fair skin. There’s no cure for rosacea, so treatments focus on management techniques. This includes wearing a broad-spectrum sunscreen and moisturizing frequently.

If you think you’re experiencing rosacea, consult your doctor. They can make a diagnosis and prescribe medication to help reduce redness.

Prescription medications include:

  • topical medications, like:
    • brimonidine (Mirvaso)
    • azelaic-acid (Azelex)
    • metronidazole (Metrogel)
  • oral antibiotics, like:
  • isotretinoin (Claravis, Accutane)

Contact dermatitis

Contact dermatitis is usually an acute condition that causes a red, itchy rash to appear on the skin. You may also experience bumps or blisters, swelling, and tenderness.

The exact cause of contact dermatitis varies from person to person, though it develops after coming into contact with something that triggers nonallergic irritation or an allergic reaction on your skin.

Common causes include:

Although it’s helpful to identify the exact cause of your contact dermatitis, there are steps you can take to treat this general rash.

This includes:

  • applying anti-itch glucocorticosteroid cream or calamine lotion
  • taking OTC anti-itch medication, such as diphenhydramine (Benadryl)
  • soaking in a cool oatmeal bath
  • avoiding scratching
  • using mild soaps without dyes or perfumes

Shop for calamine lotion here.

If your symptoms persist after one to two weeks, consult your doctor. They can make a diagnosis, if needed, and prescribe prescription-strength medication.

Eczema

Eczema is a chronic condition that can also make your skin red and itchy. Although it begins most commonly in children, it can occur at any age.

Eczema generally starts as small, raised bumps. These bumps may leak fluid if scratched. The rash can also form thickened areas of the skin — called plaques — over a larger area.

You may also experience red patches around your:

  • hands or wrists
  • feet or ankles
  • neck
  • upper chest
  • eyelids
  • face, especially the cheeks
  • scalp
  • ears
  • elbow crease
  • knees, generally on the back

You may be able to manage your symptoms by:

  • applying an anti-itch glucocorticosteroid cream or calamine lotion
  • taking an oral anti-itch medication, such as diphenhydramine (Benadryl)
  • moisturizing at least twice daily
  • taking an oatmeal bath
  • using a humidifier

Buy a humidifier online.

Consult your doctor if your symptoms persist for more than one to two weeks. They can make a diagnosis and prescribe medication.

If you’re experiencing bumps that are itchy, inflamed, and swollen, you probably have hives. Hives can often be treated at home or go away on their own without treatment.

If the bumps are hard or filled with pus or something other than clear fluid, they may be a sign of an underlying medical condition. Hives that occur along with peeling of the skin or blisters can be a sign of a serious allergic reaction.

If you develop a rash or hives after taking a medication, you should consult your doctor immediately.

You should also consult your doctor if you have:

  • a rash over your whole body
  • a fever
  • pain
  • blisters that leak yellow or green fluid

If you suspect your rash is the result of a preexisting condition that you’re currently seeking treatment for, you may benefit from a consultation. Your doctor can confirm your suspicions and take appropriate next steps.

Contact your doctor if you suspect the rash is caused by an allergen. Severe allergic reactions may result in anaphylaxis, which requires immediate medical treatment.

Rashes caused by stress may vary in how they’re treated and how long they last. A stress rash with hives will likely disappear with time and mild to moderate treatments.

You may need to see a doctor to treat stress-related skin conditions such as acne, dermatitis, or severe or long-lasting hives. If you have chronic conditions like psoriasis and rosacea, you should work with your doctor to develop an appropriate treatment plan to use in the long term.

If your rash is caused by stress, this may be a sign that you need to reduce some of the stressors in your life.

There are many methods to help ease your mind and relieve stress, including:

Once you identify techniques that help you relax and reframe your outlook, you may find that your skin condition improves.

In the meantime, you can try using OTC medications as needed to alleviate any inflammation and irritation. If your symptoms persist or if you think they’re the result of an underlying condition, consult your doctor. They can work with you to determine your next steps.
