Hygiene On and Off the Mat: What Every BJJ Fighter Needs to Know
Brazilian Jiu-Jitsu is a contact sport in the truest sense of the word. You train closely with your partners, often with direct skin contact, on a mat used daily by many athletes. This is precisely what makes BJJ so honest, intense, and direct – but also a sport where hygiene is not a minor issue.
Anyone who regularly spars and rolls bears responsibility. For their own health. For their training partners. For the entire academy.
Cleanliness in BJJ is not vanity. It is respect. And no: A rashguard does not become clean again by airing it out overnight and optimistically smelling it.
Why Hygiene in BJJ is Not a Side Issue
Grappling sports carry an increased risk of skin infections. The reason is simple: close bodily contact, sweat, friction, minor skin injuries, and shared surfaces create conditions where bacteria, fungi, and viruses can spread more easily.
The good news: Many problems can be avoided. Not through complicated measures, but through consistent routines.
Hygiene in BJJ doesn't just begin when something is visible. It begins beforehand – with clean equipment, healthy skin, short nails, and the decision not to train when sick or with suspicious skin conditions.
The Most Common Skin Infections in BJJ
You don't need to be a medical professional. But you should know what to look out for.
Ringworm / Tinea
A fungal infection often visible as a ring-shaped, reddened, scaly, or itchy skin patch. It can be transmitted through direct skin contact, shared objects, or contaminated surfaces.
Impetigo
A bacterial skin infection, often recognizable by weeping areas or honey-yellow crusts. It is contagious and should be medically evaluated.
Staphylococcal Infections, Including MRSA
Staphylococci can cause skin infections that may appear as red, painful pustules, boils, or abscesses. MRSA is an antibiotic-resistant variant and does not fall into the "let's see if it goes away" category. If suspected: pause training and get it medically evaluated.
Herpes gladiatorum
An infection caused by herpes simplex viruses, particularly known from wrestling and grappling sports. Typical symptoms include small, painful blisters or sore skin areas, often on the face, head, neck, or torso.
Important: This section is for guidance, not diagnosis. If you notice an unusual skin change, see a doctor – and do not train.
On the Mat: Hygiene During Training
Clean Gi and Rashguard – Every Time.
Your Gi should be washed after every session. The same applies to your rashguard, spats, and shorts. It's also best to always wear a rashguard under your Gi, which creates an additional barrier.
Wearing training clothes a second time is not being frugal, but a hygiene problem. Your training partner should be fighting your technique, not the smell of your equipment.
Short, clean nails.
Long fingernails and toenails injure training partners and collect dirt. Trim them regularly. This is basic. Anyone who doesn't take this seriously disrespects their training partners.
Cover wounds cleanly.
Small cuts or abrasions should be covered cleanly and securely. Open or weeping wounds do not belong on the mat. They are an entry point for germs – for you and for others.
Do not go barefoot from the mat to the restroom.
As soon as you leave the mat, put on flip-flops. Especially on the way to the restroom or through the changing room. Otherwise, anything you pick up with your feet outside will be brought back onto the mat.
No sharing of towels, razors, or clothing.
Anything that comes into direct contact with skin, sweat, or wounds is not shared. Period.
Off the Mat: What Matters After Training
Shower as soon as possible.
After training, you should shower as soon as possible. The longer sweat, dirt, and germs remain on the skin, the worse. Especially after intense rolling, showering is not an option, but part of your training routine.
Fresh towel – every time.
Use a clean towel for each session. Do not share it. Do not leave it damp in your bag for days.
Clean your gym bag regularly.
A damp bag full of sweaty clothes is a perfect breeding ground for odor, bacteria, and mold. Empty it after every training session, let it air dry, and clean it regularly.
Briefly check your skin.
After showering, a quick check is enough: new redness, blisters, open sores, crusts, or unusual skin changes? Early detection means many things can be treated more quickly and easily.
Properly Maintain Your Equipment
Gi
Wash after every session. Observe the care label and let the Gi dry completely before using it again, and yes, the belt should also be washed regularly. Damp equipment does not belong in the bag or back on the mat.
Rashguard, Spats, and Shorts
Also wash after every training. For sublimation prints and technical fabrics, it is usually better to wash the clothing inside out, avoid aggressive fabric softener, and let them dry completely. Air drying often protects the material and elasticity.
Flip-flops
Flip-flops also need to be cleaned. They are your protection between the changing room, restroom, and mat – but only if they themselves remain clean.
Mouthguard and Tape
Clean your mouthguard after every session and store it dry. Used tape goes directly into the trash, not on the edge of the mat.
When You Should Not Train
Discipline does not mean always showing up. Discipline also means making the right decision.
Do not train if you:
- have an active or untreated skin infection,
- have open, weeping, or wounds that cannot be securely covered,
- have a fever, severe cold symptoms, or a contagious illness,
- notice suspicious blisters, scabs, abscesses, or ring-shaped skin areas.
A missed training session is not a problem. An infection spreading through the academy is.
Pausing to protect others shows maturity. Rolling while sick or with suspicious skin conditions is selfish.

Hygiene is Part of the Journey
Clean equipment, short nails, a fresh towel, and the respect to not train when infection is suspected are not minor details. They are an expression of the same discipline that also makes you technically better.
Those who take the path seriously care about the details.
On the mat. Off the mat. Every day.
Grow your way, roll your way.
