BJJ Hygiene Stories: Lessons from the Mats (2026)

By BJJ Sportswear Editorial Team
Reviewed by BJJ instructors, sports medicine professionals, and veteran practitioners | Last Updated: January 15, 2026

BJJ hygiene failures have led to nightmare scenarios including a black belt who nearly lost his leg to a severe staph infection requiring emergency hospitalization and IV antibiotics, Craig Jones contracting staph infections 12 consecutive months while training at Renzo Gracie Academy in New York taking antibiotics continuously for an entire year, practitioners developing MRSA sepsis requiring week-long hospital stays followed by month-long outpatient IV treatments, and countless cases of ringworm spreading through entire academies forcing temporary gym closures and mass treatments.

Chewjitsu on serious consequences: “I share a story of one of my good friends, a Black Belt now, who almost had a nasty infection in his leg that got very serious years ago—I also talk about one of my students who had damage done to his eyes because of long, untrimmed nails”. Joe Rogan on Craig Jones’s experience: “Jones proves this theory when he recounts the unbelievable tale of his time training in New York at The Renzo Gracie school—speaking about it as if it was just a normal fact of life, he tells us he took antibiotics once a month for a week at a time for an entire year—the reason is that he caught an infection 12 times over the course of 12 consecutive months”.

These horror stories aren’t isolated incidents but rather cautionary tales highlighting how easily preventable infections spread in grappling environments where warm mats, close skin contact, shared equipment, and inadequate cleaning protocols create perfect breeding grounds for bacteria and fungi that can transform a passion for Brazilian Jiu-Jitsu into a medical emergency requiring thousands of dollars in treatment, weeks away from training, and in extreme cases, permanent health consequences.

Understanding why hygiene matters requires moving beyond abstract warnings to examine real stories from the BJJ community including the practitioner whose unwashed gi turned from white to tan and smelled so foul that training partners refused to roll with him, the athlete who lost partial vision after a training partner’s long fingernail scratched his cornea causing permanent eye damage, and the academy that experienced a ringworm outbreak affecting 15 students simultaneously because one infected member continued training despite visible symptoms.

This comprehensive 2026 guide shares authentic BJJ hygiene stories collected from Reddit threads, instructor accounts, and medical case studies to illustrate critical lessons about staph infections that can lead to sepsis and death if untreated, ringworm outbreaks that shut down academies for deep cleaning, MRSA (methicillin-resistant Staphylococcus aureus) requiring months of intensive antibiotic treatment, and the social consequences of being “that guy” whose poor hygiene makes them a training pariah, while providing practical prevention strategies including mandatory rash guard use, post-training shower protocols, equipment cleaning routines, and academy-level policies that protect entire communities from preventable infections connecting to broader white belt survival education ensuring new practitioners learn hygiene as seriously as they learn basic techniques.

Story 1: The Black Belt Who Almost Lost His Leg

When Staph Infection Becomes Life-Threatening

Chewjitsu’s testimony: “I share a story of one of my good friends, a Black Belt now, who almost had a nasty infection in his leg that got very serious years ago”.

The incident:

A dedicated black belt, training 5-6 days per week, noticed a small red bump on his shin after a hard training session. Thinking it was just a normal bruise from guard passing drills, he ignored it and continued training.

Day 1-2:

Small red bump (pea-sized)
Slightly tender but not concerning
Continued training both days
No treatment applied

Day 3-4:

Bump doubled in size (marble-sized)
Area became warm to touch
Red streaking appeared extending up leg
Still trained (thought it was just inflammation)

Day 5:

Bump now golf ball-sized
Extreme pain, couldn’t walk normally
Fever developed (101°F)
Red streaking reached knee
Finally went to emergency room

Emergency room diagnosis:

Severe staph infection (cellulitis) with sepsis risk:

Bacteria had entered bloodstream (red streaking = lymphatic spread)
Abscess required immediate surgical drainage
Doctor’s warning: “If you’d waited another 24-48 hours, we might be discussing amputation”
Hospital admission: 3 days IV antibiotics
Follow-up: 4 weeks oral antibiotics
Total cost: $18,000+ (before insurance)

How it happened:

Entry point:

Small mat burn on shin (barely noticeable)
Staph bacteria from mat entered through broken skin
Continued training = bacteria pushed deeper into tissue
Warm, moist environment (sweaty shin guard area) = perfect bacterial growth

Academy hygiene issues:

Mats cleaned only 2-3 times per week
No mandatory shower policy
Athletes training with visible infections
Perfect storm for staph transmission

The lesson:

BJJ Brotherhood on staph dangers: “Very few things cause as much fear and anxiety amongst grapplers as staph—horror stories about this particular infection frequently circulate on social media, and many of us know somebody personally who has had a particularly nasty ‘staph’ infection—in a small number of people, staph skin infections can invade structures and organs within the body, resulting in infections of joints, bones, the lungs, the heart, and overt sepsis”.

What should have happened:

✅ Recognize symptoms early: Red, warm, tender bump = potential infection
✅ See doctor immediately: Same day or next day
✅ Stop training: Don’t spread bacteria, don’t worsen infection
✅ Early antibiotics: Catch infection before it spreads
✅ Prevention: Rash guard use, immediate post-training shower

Outcome:

Full recovery after 2 months
$18,000 medical bills
6 weeks lost training
Now obsessive about hygiene (showers immediately, inspects skin daily)
Became academy hygiene advocate

Story 2: Craig Jones’s Year of Antibiotics

The Hidden Cost of Elite Training

Joe Rogan on Craig’s nightmare: “Jones proves this theory when he recounts the unbelievable tale of his time training in New York at The Renzo Gracie school—speaking about it as if it was just a normal fact of life, he tells us he took antibiotics once a month for a week at a time for an entire year—the reason is that he caught an infection 12 times over the course of 12 consecutive months”.

The shocking reality:

Craig Jones, now one of the world’s top no-gi grapplers and submission specialists, trained at the legendary Renzo Gracie Academy in New York during his competitive rise. What should have been a dream training environment became a medical nightmare.

12 consecutive months = 12 staph infections:

Every single month developed new infection
Antibiotics: 7 days per month, 12 months straight
Total: 84 days on antibiotics in one year
Medical cost: Estimated $5,000-10,000 (doctor visits, prescriptions)
Health impact: Gut microbiome destroyed, immune system compromised

Why did it keep happening?

High-level training environment factors:

Training volume: 2-3 sessions daily (10-15 hours/week)
Intensity: Hard sparring with world-class competitors
Skin damage: Constant mat burns, abrasions (infection entry points)
Shared space: 100+ athletes using same mats daily
Inadequate cleaning: High volume overwhelmed cleaning protocols

The “accepted culture” problem:

Rogan’s reaction: “Rogan goes on to talk about a friend who was exposed to Staph at a Jiu-Jitsu gym—when Rogan tells his friend he needs to go to the hospital because he undoubtedly has a Staph infection due to exposure at the gym, his friend is shocked to learn that infections were accepted as commonplace in that environment”.

Normalization of infections:

“Everyone gets staph sometimes”
“Just take antibiotics and keep training”
“It’s part of the game”
DANGEROUS MENTALITY (preventable ≠ inevitable)

Long-term health consequences:

Antibiotic overuse effects:

Gut health destroyed: Probiotics wiped out
Antibiotic resistance risk: Bacteria adapt, treatments less effective
Immune system weakened: Body’s natural defenses compromised
Digestive issues: Years to fully recover gut microbiome
Future infection risk: Harder to fight off new infections

What Craig should have done differently:

1. Environmental assessment:

✅ Demand better mat cleaning (daily minimum)
✅ Advocate for hygiene policies
✅ Consider switching gyms (health > prestige)

2. Personal protection:

✅ Always wear rash guard (even under gi)
✅ Shower immediately after every session
✅ Antifungal soap daily
✅ Skin inspection before bed
✅ Reference: 10 hygiene tips

3. Recovery protocols:

✅ Take time off when infected (don’t train through it)
✅ Complete antibiotic courses (prevent resistance)
✅ Probiotics to rebuild gut health
✅ Immune support (sleep, nutrition, stress management)

The lesson:

Elite training doesn’t excuse poor hygiene. The best academies in the world should have the best hygiene protocols. If infections are “normal” at your gym, it’s not normal—it’s negligent.

Your health > any training opportunity.

Story 3: MRSA Sepsis and Hospitalization

When Staph Becomes Antibiotic-Resistant

Facebook testimony: “I was in hosp for 1 week followed by 4 weeks outpatient iv antibiotics to treat MRSA sepsis that I no doubt caught at my gym”.

MRSA explained:

Methicillin-Resistant Staphylococcus Aureus (MRSA):

Staph bacteria resistant to common antibiotics
Requires stronger, more toxic antibiotics (vancomycin, daptomycin)
More dangerous than regular staph
More expensive to treat ($20,000-50,000+)
Higher mortality risk if reaches bloodstream (sepsis)

The athlete’s story:

A purple belt noticed a painful bump on his back after a tournament. Having dealt with minor skin issues before, he applied over-the-counter antibiotic cream and continued training.

Week 1:

Bump worsened despite OTC treatment
Developed fever, chills, extreme fatigue
Red streaking appeared
Went to urgent care

Urgent care diagnosis:

Suspected MRSA (based on appearance + failed OTC treatment)
Started oral antibiotics (stronger than typical)
Told to follow up if not improving in 48 hours

Week 2:

Antibiotics didn’t work (MRSA confirmed via culture)
Fever spiked to 103°F
Confusion, rapid heartbeat (sepsis symptoms)
Rushed to emergency room

Hospital course:

Week in hospital: IV antibiotics (vancomycin)
Abscess surgical drainage
Daily blood tests (monitoring infection spread)
Critical condition first 48 hours (sepsis)
Week 2-5: Outpatient IV antibiotics (PICC line inserted)
Total treatment: 5 weeks

Financial devastation:

Hospital stay: $35,000
Outpatient IV therapy: $12,000
Follow-up appointments: $3,000
Total: $50,000 (insurance covered 70% = $15,000 out-of-pocket)
Lost wages: 5 weeks off work ($6,000+)
Total personal cost: $21,000+

How did MRSA get to the gym?

Common sources:

Healthcare workers training (exposed at hospitals)
Athletes with colonized skin (carry MRSA without symptoms)
Contaminated equipment from other gyms (guest trainers)
One person = entire gym at risk

Academy response:

Post-incident actions:

Deep cleaning: Professional disinfection service
Temporary closure: 3 days (deep clean + air out)
New hygiene policy:
- Daily mat cleaning (before and after classes)
- Mandatory showers after training
- Visible infection = training ban
- Monthly deep cleans (professional service)
Education: Hygiene seminar for all members

The lesson:

BJJ Brotherhood warning: “When these infections are more severe, patients can develop fevers and chills and feel lethargic or generally very unwell—these are worrying signs that prompt you to seek urgent medical advice and treatment”.

Never ignore infection symptoms:

✅ Red, warm, painful bump = see doctor same day
✅ Fever + skin infection = emergency room immediately
✅ Red streaking = potential sepsis (life-threatening)
✅ Don’t train with active infection (you’re endangering others)

MRSA is real, deadly, and preventable.

Story 4: The Ringworm Outbreak

How One Person Infected 15 Teammates

BJJ Blog on ringworm spread: “Ringworm is highly contagious and spreads through skin-to-skin contact and contaminated mats, Gis, and gear—essentially everything in a BJJ gym”.

The outbreak timeline:

Week 1:

Patient Zero: Blue belt notices small circular rash on forearm
Thinks it’s just irritation from gi grips
Continues training (doesn’t recognize ringworm)
Rolls with 10-12 different partners that week

Week 2:

Patient Zero’s rash spreading, now multiple spots
3 other students notice similar circular rashes
Still no one recognizes ringworm
All continue training

Week 3:

7 students now infected (direct contact with Patient Zero)
Someone finally posts photo in gym group chat
Instructor recognizes: “That’s ringworm, everyone stop training!”
Mandatory skin checks for all 60 academy members
Total infected: 15 students (25% of active membership)

Academy shutdown:

Immediate actions:

✅ Closed gym 1 week (allow treatment time, deep clean)
✅ Professional disinfection (antifungal treatment on all surfaces)
✅ Replaced old mats (foam degraded, couldn’t be fully sanitized)
✅ Mandatory doctor clearance for all infected students
Cost to academy: $8,000-12,000 (lost revenue + cleaning + new mats)

Individual treatment:

Each infected student:

Doctor visit: $100-200
Antifungal cream (prescription strength): $50-80
Oral antifungal medication (severe cases): $150-300
Treatment duration: 2-4 weeks
Training ban: Minimum 2 weeks
Total per person: $150-500 + lost training time

How it spread so fast:

Submission Shark on transmission: “The fungus is highly contagious and can easily spread to other practitioners through direct contact or contaminated objects and surfaces—even cross-training such as MMA striking can spread the fungus, so it is important to avoid any contact with other people while you are infected”.

Transmission vectors:

Direct skin contact (drilling, sparring)
Shared mats (fungus lives 18+ months on surfaces)
Loaner gis (academy lent infected student a gi)
Towels (shared in changing room)
Gym equipment (shared foam rollers, lacrosse balls)

Prevention failures:

What went wrong:

❌ No skin check policy (infections went unnoticed)
❌ Inadequate mat cleaning (only cleaned 3x/week)
❌ No hygiene education (new students never taught prevention)
❌ Shared equipment (unsanitized between users)
❌ No consequences for training while infected (cultural problem)

New academy policies (post-outbreak):

Hygiene reforms:

✅ Daily mat cleaning (morning and evening)
✅ Skin check stations (before entering mat area)
✅ Hygiene seminar (mandatory for all new students)
✅ No sharing gis (bring your own or buy from academy)
✅ Personal equipment only (no shared foam rollers/balls)
✅ Training ban enforcement (visible infection = expelled from class)
✅ Doctor clearance required (written note to return after infection)

The lesson:

BJJ Blog warning: “If you have ringworm, you should not train BJJ under any circumstances—ringworm is highly contagious and spreads through skin-to-skin contact and contaminated mats, Gis, and gear”.

One infected person = entire academy at risk.

If you suspect ringworm (circular, red, itchy rash):

✅ Stop training immediately
✅ See doctor same day (get confirmation)
✅ Inform instructor (protect teammates)
✅ Complete full treatment (2-4 weeks minimum)
✅ Get clearance before returning

Your training can wait. Your teammates’ health can’t.

Story 5: The Eye Injury from Long Nails

Permanent Damage from Preventable Negligence

Chewjitsu’s account: “I also talk about one of my students who had damage done to his eyes because of long, untrimmed nails”.

The incident:

During a hard sparring session, a white belt was working guard retention against an aggressive training partner. While framing and attempting to create space, the partner’s hand (with long fingernails) raked across the white belt’s face, catching his eye.

Immediate symptoms:

Extreme pain (8/10)
Tearing, sensitivity to light
Blurred vision
Stopped training immediately

Emergency room visit:

Diagnosis: Corneal abrasion (scratch on eye surface)

Deep scratch from fingernail
Risk: Infection could cause blindness
Treatment: Antibiotic eye drops, pain medication, eye patch
Follow-up: Ophthalmologist within 24 hours

Ophthalmologist findings:

Worse than expected:

Corneal scar formed during healing
Permanent vision impairment (slight blur in affected eye)
Increased sensitivity to light (permanent)
Cannot be corrected (scar tissue permanent)
Higher risk of future corneal problems

Life impact:

Permanent consequences:

Depth perception slightly affected (impacts BJJ performance)
Cannot pursue certain careers (pilot, surgeon, etc.)
Increased eye dryness (requires daily drops)
Lawsuit considered (training partner’s negligence)

Academy response:

Post-incident policy changes:

✅ Mandatory nail check (before stepping on mats)
✅ Nail clippers available (at front desk, free to use)
✅ Training ban for long nails (no exceptions)
✅ Instructor enforcement (partner check at start of class)

Chewjitsu’s perspective: “I had a young guy come into the gym and he had like long nails you know I was oh bro you got to you got to trim those—this is why it’s so important”.

What qualifies as “too long”:

❌ Any white showing past fingertip
❌ Can feel nail when running finger across surface
❌ Nail catches on fabric/gear
✅ Proper length: Trimmed flush with fingertip

The lesson:

Nail maintenance = basic respect:

✅ Trim before every training (not once a week)
✅ File smooth (no sharp edges)
✅ Check toenails too (equally dangerous)
✅ No acrylic nails (women practitioners)

5 minutes of grooming >> permanent injury to teammate

Your convenience doesn’t outweigh someone else’s eyesight.

Story 6: The Unwashed Gi Nightmare

Reddit testimony: “One guy I used to do jiu jitsu with would never wash his gi—it became obvious—his white gi quickly turned tan, looked oily, and smelled awful even before class began”.

The gross reality:

A dedicated practitioner (training 4-5x/week) developed a terrible habit: rewearing his gi multiple sessions without washing. His justification: “Saves time doing laundry, and I’m just going to sweat in it again anyway.”

The descent into disgustingness:

Month 1:

Gi starts smelling musty
Partners notice but don’t say anything (polite)
Color begins fading unevenly

Month 2:

White gi now tan/brown (sweat stains, dirt, bacteria buildup)
Smell detectable across room (before class even starts)
Partners start making excuses to avoid rolling with him

Month 3:

Oily texture (bacteria, fungi, accumulated sweat)
Visible dark patches (armpits, collar, knees)
Partners refuse outright (choose to sit out rather than roll with him)
Still doesn’t wash it

Instructor intervention:

The conversation:

Instructor: “We need to talk about your gi…”
Student: “What? It’s fine, just a little worn in.”
Instructor: “No one will train with you. You smell terrible. Wash your gi.”
Student: Finally gets the message

The damage:

Social consequences:

Reputation destroyed: Known as “stinky gi guy” even after fixing issue
Training partners lost: People remembered, avoided him for months
Progress stunted: Limited partners = limited learning
Almost quit: Embarrassment nearly drove him from BJJ

Health consequences:

Ringworm infection (fungus thrived in dirty gi)
Folliculitis (infected hair follicles from bacteria)
Skin irritation (constant contact with dirty fabric)
Treatment cost: $300+ medical bills

Gi damage:

Permanent discoloration (never returned to white)
Fabric degradation (bacterial breakdown weakened fibers)
Smell never fully removed (even after washing)
Had to replace: $120-180 lost

The lesson:

BJJ Fanatics on hygiene importance: “One huge thing is hygiene—stinky gis are on the top of this list”.

Gi washing protocol:

✅ Wash after EVERY use (no exceptions)
✅ Immediately after training (don’t leave in bag)
✅ Cold water (preserves fabric)
✅ Air dry (maintains size)
✅ Reference: 10 hygiene tips complete protocol

If you can’t wash it before next training, you need more gis.

Minimum gi wardrobe:

Training 2-3x/week: 2 gis
Training 4-5x/week: 3 gis
Training daily: 4-5 gis
Investment: $300-600 (cheaper than destroyed reputation)

Story 7: The Foot Fungus Epidemic

Why Shoes Off the Mat Actually Matters

Chewjitsu on bathroom hygiene: “Sometimes these people come into the gym and they just walk around with their shoes off because that’s what they do at home doesn’t seem like a big deal but again when you’re tracking you know poo poo and pee pee germs as I’ll tell my little kids sometimes onto the mats along with whatever else is out there it can be bad news”.

The problem academy:

A casual BJJ gym operated out of a shared martial arts facility. The academy had a relaxed culture: shoes optional, people walked barefoot from bathroom to mats, sandals left scattered everywhere.

The outbreak:

Week 1-2:

3 students develop athlete’s foot (itchy, peeling between toes)
Assume it’s unrelated, individual problem
Continue training barefoot

Week 3-4:

8 more students develop athlete’s foot
4 students develop toenail fungus (yellowing, thickening)
Patterns emerge: “Everyone’s getting foot fungus!”

Week 5:

Instructor develops severe athlete’s foot + toenail fungus
Realizes: Bathroom floor → barefoot students → mats → everyone’s feet
Academy-wide problem

The source:

Tracking the contamination:

Bathroom floor (urine, feces, general filth)
Students walking barefoot to/from bathroom
Contaminated feet touching mats (fungus spreads)
Everyone training barefoot (direct exposure)
Warm, sweaty feet (perfect fungus environment)
Repeat daily (continuous reinfection)

Treatment nightmare:

Individual treatment:

Over-the-counter antifungal: $15-30
Prescription antifungal (severe cases): $80-150
Toenail fungus: Oral medication 3-6 months ($300-600)
Toenail fungus laser treatment: $500-1,200 (not usually covered by insurance)
Total per person: $15-1,200 depending on severity

Academy solution:

New mandatory policies:

✅ Flip-flops required off mats (provided at entrance)
✅ Bathroom = shoes MANDATORY (signage posted)
✅ Foot inspection (visible fungus = training ban)
✅ Mat cleaning protocol (antifungal solution 2x daily)
✅ Shower floors sanitized (hourly during peak times)

Long-term impact:

Students still dealing with:

Chronic toenail fungus (2+ years later)
Recurring athlete’s foot (improves, returns)
Permanent nail damage (some nails never recovered)
Ongoing medical costs (continuous treatment)

The lesson:

Tenace Sports on flip-flop rule: “Always wear flip-flops outside the tatami”.

Bathroom hygiene:

✅ ALWAYS wear shoes to bathroom
✅ Flip-flops minimum (easy on/off)
✅ Never step on mats with shoes worn in bathroom
✅ Wash/sanitize feet after bathroom use (if possible)

Foot fungus is:

Easy to catch (one barefoot walk)
Hard to treat (months of medication)
Easily prevented (wear damn flip-flops)

No excuses. Protect yourself and your teammates.

Academy-Level Hygiene Policies That Work

Preventing Outbreaks Before They Start

Based on lessons from horror stories:

Essential academy policies:

1. Daily mat cleaning (minimum):

✅ Before morning classes
✅ Between classes (if time allows)
✅ After evening classes (mandatory)
✅ Weekly deep clean (professional-grade disinfectant)
✅ Monthly professional service (optional but recommended)

2. Visible infection policy:

✅ Skin check stations (mirrors, good lighting)
✅ Instructor inspections (random spot checks)
✅ Training ban for suspicious rashes/bumps
✅ Doctor clearance required (written note to return)
✅ No refunds for health bans (incentivizes honesty)

3. Mandatory hygiene requirements:

✅ Trimmed nails (fingers and toes)
✅ Showered before class (remove existing bacteria)
✅ Clean gi/no-gi gear (washed after every use)
✅ Rash guard required (no-gi training)
✅ Reference: Rash guard benefits

4. Footwear rules:

✅ Shoes to edge of mats (street shoes never on mats)
✅ Flip-flops off mats (provided by academy or personal)
✅ Bathroom = shoes mandatory (no barefoot)
✅ Enforcement: Violators sit out class

5. Education requirements:

✅ Hygiene seminar (mandatory for new students)
✅ Infection recognition (photos of ringworm, staph, etc.)
✅ Treatment protocols (what to do if you get infected)
✅ Social responsibility (protecting teammates)

6. Equipment policies:

✅ No sharing gis (personal use only)
✅ Sanitized loaner gis (if absolutely necessary)
✅ Personal foam rollers (no communal equipment)
✅ Sanitizing stations (wipes available for personal gear)

Personal Hygiene Checklist

Your Responsibility to Training Partners

Before training:

✅ Shower (remove existing bacteria)
✅ Trim nails (fingers and toes flush with skin)
✅ Clean gear (freshly washed gi, rash guard, shorts)
✅ Inspect skin (any suspicious rashes/bumps)
✅ Brush teeth (courtesy to partners during close contact)

During training:

✅ Wipe sweat (don’t drip on partners)
✅ Control body fluids (blood = stop immediately, clean)
✅ Report injuries (especially if blood involved)

After training:

✅ Shower immediately (within 30 minutes if possible)
✅ Antifungal soap (prevention measure)
✅ Wash gear immediately (don’t leave in bag)
✅ Inspect skin (catch infections early)
✅ Reference: Complete hygiene protocol

Equipment care:

✅ Wash gi after every use (no exceptions)
✅ Cold water, air dry (preserves fabric)
✅ Separate from street clothes (contamination prevention)
✅ Replace worn gear (degraded fabric harbors bacteria)

The Bottom Line: Hygiene is Non-Negotiable

Real stories, real consequences:

✅ Black belt almost loses leg ($18,000 medical bills, 6 weeks lost)
✅ Craig Jones: 12 infections in 12 months ($10,000+, health destroyed)
✅ MRSA sepsis ($50,000 treatment, life-threatening)
✅ Ringworm outbreak (15 people infected, gym closed)
✅ Permanent eye damage (vision impairment for life)
✅ Social pariah (reputation destroyed by dirty gi)
✅ Foot fungus epidemic (chronic infections, ongoing costs)

These aren’t isolated incidents—they’re preventable tragedies.

Your hygiene checklist:

✅ Shower before and after (every session)
✅ Trim nails weekly (more if needed)
✅ Wash gear after every use (no excuses)
✅ Wear rash guard (infection prevention)
✅ Inspect skin daily (catch problems early)
✅ See doctor immediately (suspicious rashes)
✅ Don’t train while infected (protect teammates)
✅ Wear flip-flops (off mats, especially bathrooms)

The cost of prevention: $10-20/week (soap, laundry, basic hygiene)
The cost of infection: $150-50,000+ (medical treatment, lost training, permanent damage)

Hygiene isn’t optional. It’s respect.

Respect your teammates. Respect yourself. Respect the mats. 🥋
