How to Prevent Ringworm and Staph in BJJ (Mat Hygiene Guide)

Quick answer: Prevent skin infections in BJJ by showering immediately after every session, washing your gi and rashguard after every use, covering any open cuts, not walking barefoot off the mat, and training at gyms that clean their mats daily. Catch issues early: if you see a ring-shaped rash or a hot, swollen red spot, stop training and see a doctor.

BJJ is a close-contact sport, which means skin-to-skin and skin-to-mat contact all class long. That makes hygiene a real part of training, not an afterthought. The good news: skin infections like ringworm and staph are very preventable with a few simple habits. Here's the complete guide.

The main infections to know

• Ringworm — a fungal infection (not a worm) that shows up as a red, ring-shaped, sometimes itchy patch. It's common in grappling and very treatable.

• Staph / MRSA — bacterial infections that can look like a spreading red area, a hot swollen bump, or a pimple-like sore that worsens. These are more serious and need prompt medical care.

• Impetigo and herpes gladiatorum also circulate in grappling gyms. The prevention habits are the same.

Shower immediately after training

This is the single most important habit. Shower as soon as possible after every session — ideally within an hour — with soap, paying attention to your whole body. The longer bacteria and fungus sit on your skin, the more chance they have to take hold. Many grapplers use an antibacterial or antifungal soap as extra insurance.

Wash your gear every single time

Your gi, rashguard, shorts, and spats hold sweat and microbes from everyone you trained with. Wash them after every use — never re-wear a "only trained once" gi. Cold water and air-drying keep your gi in shape; see our full guide on how to wash a BJJ gi. Don't forget to wipe down knee pads, ear guards, and your gym bag periodically too.

Cover cuts and protect your skin

Open cuts and scrapes are entry points for infection. Cover any broken skin with a waterproof bandage before training, and if a cut is large or won't stay covered, sit out until it heals. Keeping your skin moisturized (not cracked) also helps your natural barrier do its job.

Don't spread it around the gym

• Never walk barefoot off the mat — wear slides to the bathroom and back. Bare feet carry bacteria onto the mat and bring it back to you.

• No shoes on the mat, ever — they track in everything from outside.

• Don't train sick or with an active skin issue. Staying home protects everyone, and a good gym will thank you for it.

Choose a clean gym

You can do everything right and still be at risk if the mats are filthy. A quality gym mops and disinfects its mats daily, smells clean, and has a culture where people shower and wash gear. Mat cleanliness is one of the biggest things to check when choosing a gym — sticky or smelly mats are a real red flag.

Catch problems early

Check your skin regularly. If you spot a ring-shaped rash, a hot and swollen red area, or a sore that's spreading or won't heal, stop training and see a doctor or pharmacist promptly. Early treatment is quick and easy; ignoring it risks a worse infection and spreading it to your teammates. Don't train again until a professional clears you.

The takeaway

Skin infections are a manageable part of grappling, not a reason to avoid the sport. Shower right after class, wash your gear every time, cover cuts, keep bare feet off the mat, train at a clean gym, and act fast if something looks off. Those simple habits keep you — and everyone you roll with — healthy.

Your simple post-training checklist

Build a routine you do every single session and infections become rare. Right after class: change out of your sweaty gear immediately, shower with soap within the hour, and check your skin for anything new. At home: wash your gi, rashguard, and shorts; let them dry fully; and re-cover any healing cuts. Weekly: wipe down your gym bag, ear guards, and knee pads, which quietly harbor bacteria. None of this takes more than a few minutes, and it's the difference between training year-round and losing weeks to an infection you could have avoided.
