5 Skin Infections Every BJJ Fighter Should Know

Brazilian Jiu-Jitsu (BJJ) is a sport that pushes your mind and body to the limit. But while you sharpen your technique and test yourself on the mats, there’s an invisible opponent waiting: skin infections.

From ringworm to staph, infections spread fast in grappling gyms. One careless training session can turn into weeks off the mats. For fighters and athletes in the UAE — where sweat, heat, and humidity add extra risk — hygiene isn’t a luxury. It’s your first line of defense.

In this article, we’ll break down the five most common skin infections fighters face, why they spread so easily, and how to stay protected with smart hygiene habits.


1. Ringworm (Tinea Corporis)

What it is: Despite the name, it’s not caused by a worm — it’s a fungal infection. Ringworm shows up as circular, red, itchy patches on the skin, often with a slightly raised edge.

Why fighters get it: BJJ mats are the perfect breeding ground for fungi. Constant skin-to-skin contact, damp rashguards, and shared training spaces mean ringworm spreads like wildfire. Wrestlers and grapplers are at high risk, with prevalence rates reported as high as 20–77% in some studies (PMC).

How to prevent it:

  • Shower immediately after training — don’t sit around in sweaty gear (CDC).
  • Use soaps with natural antifungal properties, such as tea tree and oregano oils, which show activity against Trichophyton fungi (causing ringworm and athlete’s foot) (PMC).
  • Wash your gi, rashguards, and towels after every use.


2. Staph Infection (Staphylococcus Aureus)

What it is: A bacterial infection that starts small (like pimples, boils, or red bumps) but can become serious if untreated. Some strains of staph, including MRSA, are resistant to antibiotics — meaning prevention is key.

Why fighters get it: Tiny cuts, mat burns, or scratches are an open invitation for staph. Add in sweaty mats and close contact, and the bacteria spreads easily.

How to prevent it:

  • Cover cuts and scrapes with athletic tape or bandages before rolling (CDC).
  • Never train if you notice unusual sores or pus-filled bumps.
  • Wash with botanical antibacterial soaps like tea tree and myrrh, both of which show antibacterial effects against S. aureus (PubMed).


3. Impetigo

What it is: A highly contagious bacterial infection that appears as red sores, blisters, or honey-colored crusts.

Why fighters get it: Impetigo thrives in humid environments — making UAE gyms a hotspot. Close contact spreads it quickly across skin-to-skin interactions.

How to prevent it:

  • Avoid training if you or your partner have visible sores (CDC).
  • Don’t share towels, water bottles, or personal gear.
  • Stick to a strict post-training shower routine with protective soap — natural actives like sidr and myrrh have documented antimicrobial and wound-healing properties (PMC).


4. Athlete’s Foot (Tinea Pedis)

What it is: A fungal infection that usually starts between the toes — itching, scaling, and cracking skin are classic symptoms.

Why fighters get it: Training barefoot on sweaty mats, then using shared showers and locker rooms, makes it easy to pick up.

How to prevent it:

  • Wear flip-flops in communal showers and locker rooms (Children’s Hospital Vanderbilt).
  • Dry your feet thoroughly after washing.
  • Use antifungal soaps and powders if you’re prone to it — tea tree oil is especially effective against the fungi that cause athlete’s foot (PMC).


5. Folliculitis

What it is: Inflammation or infection of the hair follicles, often mistaken for acne. Appears as clusters of small red bumps or white-headed pimples.

Why fighters get it: Sweat, friction from rashguards, and even shaving body hair can all trigger folliculitis. Once infected, it spreads fast.

How to prevent it:

  • Shower as soon as possible after training — don’t let sweat sit on your skin (NFHS Sports Hygiene Guidelines).
  • Avoid harsh body washes that strip and irritate.
  • Use gentle, natural cleansing bars with antibacterial properties like tea tree and oregano (PubMed).


The Bigger Picture: Prevention Is Part of Training

Your opponent on the mats isn’t the only one you need to defend against. These skin infections can sideline even the toughest athletes. But with the right hygiene habits, you can stay healthy, sharp, and consistent in training.

  • Train hard, but shower harder.
  • Keep your gear as clean as your technique.
  • Choose natural soaps that protect, restore, and keep you battle-ready.
