How Can I Stop Itching When Sweating And Where To Find Relief

Most people don’t think twice about sweating. It’s a natural process that helps keep our bodies cool and regulates body temperature. However, for some people, sweating can be a constant source of irritation and itchiness.

If you’re one of those people, you may wonder what the cause of your itchy skin is.

In this post, we’ve compiled a list of the best tips and tricks to stop itching when sweating and get back to your life.

Causes of itchy skin when you sweat


Dehydration is one of the most common causes of itchy skin when you sweat, whether due to heat or psychological stress. When your body is dehydrated, your skin can become dry and irritated. This can lead to itchiness, redness, and flaking. To prevent dehydration-related heat rash, drink plenty of water throughout the day. You should also avoid diuretics such as caffeine and alcohol, which can further dehydrate your skin. If your urination is dark yellow, that’s a sign that you must increase your fluid intake.

Clothing that’s too tight or made of materials that irritate the skin

Another common cause of itchy skin when you sweat is clothing that’s too tight or made of irritating materials. Tight clothing can rub and chafe against your skin, causing irritation. Synthetic fabrics such as polyester and nylon can also irritate the skin, especially when wet with sweat. To avoid this, opt for loose-fitting clothing made of breathable materials that can help keep your skin cool. For example, try to wear loose cotton clothing. You should also avoid clothes that irritate the skin, such as wool.

Poor Hygiene

Another possible cause of itchy skin from too much sweating is poor hygiene. If you don’t shower regularly or if you don’t clean your clothes often, sweat and bacteria can build up on your skin and clothing, leading to irritation and itchiness. To combat this, ensure you’re showering at least once a day and washing your workout clothes after every use. You may also consider using an antiperspirant or deodorant to help keep sweat and bacteria at bay. 


A third possible cause of itchy skin when you sweat is allergies. For example, suppose you have allergies to certain fabrics or detergents. In that case, those allergens can irritate your skin when they come into contact with sweat. To combat this, try to avoid Sweaty garments made with fabric to which you’re allergic and use hypoallergenic laundry detergent on your workout clothes.

It may also be that you have a sweat allergy or hypersensitivity to the actual contents of the sweat. You may also want to consider seeing an allergy specialist who can help you identify your specific allergies and develop a plan to avoid them.

Sweat Dermatitis

A fourth possible cause of itchy skin when you sweat is sweat dermatitis, a type of eczema triggered by sweating. If you have this condition, your sweat glands cannot properly regulate the amount of sweat they produce, leading to irritation and itchiness as excessive sweat accumulates. Treatment for this condition typically involves using medications like corticosteroids or antihistamines.

Certain medications

Another possible cause of itchy skin when you sweat is certain medications. Some medications, such as those used to treat psoriasis, can cause itchiness as a side effect. If you’re taking medication and you develop a heat rash or prickly heat, talk to your doctor about whether the medication could be the cause. They may be able to adjust your dosage or switch you to a different medication.

How to stop itching when sweating

Drink plenty of fluids

When you perspire, your body loses water and electrolytes. Therefore, drinking plenty of fluids is essential to replenish these lost nutrients, especially in hot weather and humid climates. Of course, water is the best choice, but you can also drink sports drinks or fruit juices. Just make sure to avoid caffeinated beverages, as they can make you dehydrated. 

Keep your skin clean

When you sweat, the salts in your sweat can irritate your skin and cause itchiness. To prevent this, it’s essential to keep your skin clean. Wash the sweat off with mild soap and cool water as soon as possible after sweating. 

Avoid allergens

If you have allergies, you may be more susceptible to itchiness when you sweat. To prevent this, avoid things that trigger your allergies, such as pollen, dust mites, mold, and pet dander. 

Use a gentle soap on your skin

Some soaps can be harsh on your skin and strip away its natural oils. This can lead to dryness and promote itching. To stop itching when sweatung, look for a gentle soap that is hypoallergenic and free of fragrances and other harsh chemicals.

What to do if you experience skin irritation when you sweat

Apply a Cool Compress to the Area 

One of the first things you can do is apply a cool compress to the itchy area. This will help to soothe your skin and provide some relief from the itchiness. Next, simply soak a clean cloth in cool water and apply it to the affected area for 5-10 minutes. Repeat as needed throughout the day. Be sure to dry the area thoroughly after each application.

Drink Plenty of Fluids 

It’s important to stay hydrated when you have a tingling itch because dehydration can make the itching worse. So be sure to drink plenty of fluids throughout the day, especially water. You can also try sipping on herbal tea or juice to help hydrate your skin from the inside out.

Take a Cool Bath 

If your itching is widespread or particularly bothersome, you may want to take a cool bath. Add soothing herbs like lavender or chamomile to the water to help calm your skin. You can also add colloidal oatmeal, which can help to reduce itching and relieve dryness. Avoid hot water, as this can strip away natural oils and worsen your irritated skin. Spend no more than 15 minutes in the tub.

Apply a Soothing Lotion or Cream 

One of the quickest and easiest ways to soothe itchy skin or sweat rash is to apply a lotion or cream. Look for products that contain ingredients like aloe vera, chamomile, or cucumber, as these can help to calm and moisturize the skin. Calamine lotion is another excellent choice. Avoid any creams or lotions that contain alcohol, as this can further dry your skin and make the itching worse.

If you don’t have any lotion on hand, cornstarch can help to soothe skin irritation. Simply apply a thin layer of cornstarch paste to the affected area and let it sit for 10-15 minutes to dry. Then, rinse it off with cool water and repeat as needed.

Take an Antihistamine

If your itchy skin is caused by an allergic reaction, you may want to take an over-the-counter antihistamine. This can help to relieve the itching and any other symptoms you may be experiencing. Just follow the package directions carefully and avoid taking more than the recommended dosage.

See a Doctor if the Itching Persists
