Rash from Rash Guard: How to Treat It

Rash from Rash Guard Why It Happens and How to Treat It

If you’ve ever experienced Rash from Rash Guard, you’re not alone. Rash guards, designed to protect your skin from sun and abrasions during water sports, can sometimes cause skin irritation. This irritation, often manifesting as a red, itchy rash, can be due to several factors.

The tight fit, which is essential for reducing drag in the water, can cause friction against your skin, especially in sensitive areas. Additionally, the materials used in rash guards, like spandex or nylon, can trap sweat and moisture, creating an environment where bacteria and fungi thrive, further irritating the skin.

Treating a rash from a rash guard involves a few simple steps. First, make sure to thoroughly clean the affected area with gentle soap and water to remove any irritants. Applying an over-the-counter hydrocortisone cream can help reduce inflammation and itching. It’s also important to keep the area dry and avoid wearing the rash guard until the rash heals completely.

Why Do Rashes Occur from Wearing Rash Guards?

Friction and Irritation

One of the most common reasons why people develop rashes from wearing rash guards is friction and irritation. The snug fit of a rash guard combined with repetitive movements during activities such as swimming, surfing, or other water sports can lead to friction against the skin, causing irritation and inflammation.

Fabric Sensitivities

Another factor that can contribute to rashes from rash guards is fabric sensitivities. While most rash guards are made from synthetic materials such as polyester or spandex, some individuals may have sensitivities or allergies to certain fabrics. This can manifest as itching, redness, or a rash when the skin comes into contact with the fabric of the rash guard.

Moisture and Sweat Buildup

Moisture and sweat buildup underneath a rash guard can create a warm, humid environment that is conducive to the growth of bacteria and fungi. This can lead to skin infections such as folliculitis or fungal infections, which can cause itching, redness, and irritation.

How to Treat a Rash from a Rash Guard

1. Wash the Affected Area

If you develop a rash from wearing a rash guard, the first step is to gently wash the affected area with mild soap and lukewarm water. This can help remove any irritants or bacteria that may be contributing to the rash.

2. Apply a Cold Compress

Applying a cold compress or cool, damp cloth to the rash can help soothe itching and reduce inflammation. Simply place the compress on the affected area for 10-15 minutes at a time, several times a day as needed.

3. Use Over-the-Counter Remedies

Over-the-counter remedies such as hydrocortisone cream or calamine lotion can help alleviate itching and inflammation associated with rashes. Apply a thin layer of the cream or lotion to the affected area according to the manufacturer’s instructions.

4. Keep the Skin Dry and Clean

To prevent further irritation and promote healing, it’s essential to keep the skin dry and clean. Avoid wearing tight clothing or abrasive fabrics that may exacerbate the rash, and shower promptly after swimming or engaging in activities that cause sweating.

5. Seek Medical Attention if Necessary

If the rash persists or worsens despite home treatment, or if you experience symptoms such as fever, pus-filled blisters, or spreading redness, it’s important to seek medical attention promptly. A healthcare professional can provide a proper diagnosis and recommend appropriate treatment options.

Preventing Rashes from Rash Guards

Choose the Right Size and Fit

Ensuring that your rash guard fits comfortably and provides adequate coverage without being too tight can help prevent friction and irritation against the skin.

Opt for Moisture-Wicking Fabric

Choosing a rash guard made from moisture-wicking fabric can help keep the skin dry and reduce the risk of moisture and sweat buildup, which can contribute to skin irritation and rashes.

Wear a Rash Guard with UPF Protection

Look for rash guards that offer UPF (ultraviolet protection factor) protection to shield the skin from harmful UV rays. This can help prevent sunburns and reduce the risk of skin irritation caused by prolonged sun exposure.

Take Breaks and Allow the Skin to Breathe

If engaging in activities that require wearing a rash guard for an extended period, such as surfing or snorkeling, be sure to take breaks and allow the skin to breathe. Removing the rash guard periodically can help reduce friction and minimize the risk of developing a rash.

Practice Proper Skin Care

Maintaining good skin hygiene and moisturizing regularly can help keep the skin healthy and resilient, reducing the likelihood of developing rashes or other skin problems.


While rash guards offer valuable protection against sun exposure and skin abrasions, some individuals may experience skin irritation or rashes from wearing them.
