Mat Hygiene 101.

BJJ is a close-contact sport, which means hygiene is not optional, it is how everyone stays healthy. The good news is that a few simple habits keep skin issues away almost entirely. Here is the beginner's guide to training clean.

Why it matters

Because you are in close contact with partners and the mat, grappling can occasionally spread skin issues like ringworm (a common, treatable fungal infection) or staph if hygiene is sloppy. These are easy to avoid. A clean gym and clean habits make them rare.

Your personal hygiene checklist

• Wash your gear after every session. Gi, rashguard, shorts, belt, all of it, every time.
• Shower right after training, ideally as soon as you get home, with soap.
• Trim your finger and toenails short so you do not scratch anyone.
• Cover any cuts or scrapes with a waterproof bandage before training.
• Wear clean clothes to every class. Never re-wear sweaty gear.
• Use sandals off the mat, especially to and from the bathroom, and keep shoes off the mat.

Do not train sick or with a skin issue

If you have a fever, a cold you could pass on, or an unexplained rash, stay home and get it checked. It is the single most considerate thing you can do for your training partners. Nobody will be upset, we will all be glad you did.

What a good gym does

Hygiene is a shared responsibility, and a good gym holds up its end. Mats should be cleaned regularly, the space kept tidy, and a culture of cleanliness encouraged. When you visit a gym, a clean mat and fresh-smelling room are a great sign.

If something does show up

If you ever notice an unusual patch of skin, do not panic and do not train on it. See a pharmacist or doctor, most skin issues clear up quickly with simple treatment, and rest until it is gone. Catching it early and staying off the mat protects everyone.

The bottom line

Clean gear, short nails, a quick shower, and covering cuts. Do those, and skin issues become a non-issue. Hygiene is just part of being a good training partner, and it keeps the whole room healthy.
