Training in a martial arts gym, especially one focused on Brazilian Jiu Jitsu, brings tremendous benefits. These benefits include better fitness, discipline, camaraderie, self-defense skills, humility. But such close-contact sport also comes with responsibilities. Cleanliness is not optional. But it is essential for health, safety, and respect. When hygiene is neglected, risks increase: skin infections, unpleasant odors, illness, even injuries.

This guide brings together the essential hygiene rules every practitioner should know. These rules are underpinned by expertise and real-world experience. It does not matter if you are a white belt just starting, or a seasoned BJJ black belt. Caring for your Gi, your body, and your gym environment makes a huge difference.

1. Why Hygiene Matters in Brazilian Jiu Jitsu

a) Infection Prevention & Health

Skin-to-skin contact is inherent in BJJ: grappling, rolling, sweeps, submissions. This creates ideal conditions for bacteria, fungi, viruses. Without good hygiene, athletes risk ringworm, staph infections (MRSA), fungal infections such as athlete’s foot, impetigo, etc.

Shared surfaces i.e. mats, restroom floors, changing rooms can harbor pathogens. A sweaty Gi left untreated is a breeding ground for microbes.

b) Respect & Gym Culture

Cleanliness fosters respect among training partners. Nobody wants to roll with someone whose Gi smells, or who has not showered post-workout. Good hygiene is part of martial values: integrity, discipline.

c) Performance & Comfort

A clean, well-maintained Gi grips better, moves better. Hygiene affects grip, glove use, wrist wraps, etc. Smelly gear or body can distract, reduce confidence, affect effort.

d) Gym Reputation & Retention

Gyms that enforce high hygiene standards tend to retain members, avoid legal issues, and foster trust. New students will compare first impressions: odor, dirty mats, mold, bad changing rooms.

2. Key Body Hygiene Practices

• Rule 1: Shower Before & After Training

  Pre-training: A quick shower helps remove outside bacteria, sweat, body oils. Clean skin reduces irritation under the Gi and prevents spreading microbes.

  Post-training: Shower immediately to rinse off sweat and grime. Dry thoroughly, especially skin folds and nails.

• Rule 2: Keep Nails Trimmed and Clean

  Fingernails and toenails must be short and clean to avoid scratches and bacteria buildup.

• Rule 3: Hair Hygiene

  Wash hair regularly. Tie long hair back. Keep beards neat and clean.

• Rule 4: Use Clean Under-Gear

  Always wear clean rash guards, spats, and under-shorts. Do not reuse unwashed gear.

• Rule 5: Overall Clothing Hygiene

  Wash Gi, belt, and gear after each use. Rotate between multiple Gis if possible.

• Rule 6: Avoid Training When Sick or Injured

  Stay home if you have infections, skin conditions, or open wounds.
