Mat burn is one of Brazilian Jiu-Jitsu’s least prestigious badges of honour.
It commonly appears after skin repeatedly rubs against mats, gis or rashguards. Knees, elbows, feet, toes and the tops of the ankles tend to take the most punishment.
Although people call it a “burn,” mat burn is usually a superficial friction injury or abrasion. The affected area may look red and feel tender. In some cases, the outer layer of skin is scraped away.
This guide provides general information for minor mat burn. It is not a diagnosis or substitute for professional medical advice.
What Causes Mat Burn in BJJ?
Mat burn occurs when friction damages the surface of the skin.
Common situations include:
- Shooting takedowns repeatedly.
- Dragging the tops of the feet across the mat.
- Escaping from bottom position.
- Wrestling on rough mats.
- Training in poorly fitting clothing.
- Repeating the same movement over many rounds.
- Training on already irritated skin.
Sweat and moisture can also make the skin more vulnerable to friction.
Step 1: Stop and Inspect the Area
Do not ignore broken skin simply because the injury looks small.
Check:
- How large the affected area is.
- Whether it is bleeding.
- Whether dirt or debris is present.
- Whether the skin can be covered securely.
- Whether continuing to train would reopen it.
If the area is actively bleeding or cannot be securely covered, stop training.
Step 2: Clean Minor Mat Burn
For a small graze or abrasion, rinse the area and clean it gently.
NHS first-aid guidance recommends cleaning minor cuts and grazes and covering them with an appropriate dressing.
Avoid grinding a rough cloth into the injury. Remove obvious debris gently and wash your hands before and after handling the area.
Do not put ordinary cosmetic skincare products directly into an open wound unless the product is specifically intended and labelled for that use.
Step 3: Cover Broken Skin
Once the area is clean, cover it with a clean dressing suitable for the location and type of wound.
Athlete-hygiene guidance recommends covering cuts and wounds, particularly in close-contact environments.
A secure covering helps protect the damaged area from additional rubbing and keeps open skin away from shared surfaces.
Change the dressing when it becomes wet, dirty or loose, following appropriate wound-care guidance.
Step 4: Give It Time to Settle
The fastest way to turn a minor abrasion into a persistent problem is to tear it open every evening.
Consider whether the location allows you to train without disturbing it. Mat burn on the top of the foot, for example, can repeatedly reopen during shots, technical stand-ups and guard movement.
One missed session may allow the surface to recover more effectively than five consecutive sessions of tape, blood and denial.
Step 5: Moisturise the Surrounding Intact Skin
Dry, rough skin may be more vulnerable to friction and cracking.
After the wound has closed, a moisturiser or balm can help keep the surrounding intact skin feeling comfortable and flexible.
GRIP Recovery Balm is designed for dry, rough areas of intact skin after training. It is not presented as a treatment for infection or a replacement for medical wound care.
Can You Train With Mat Burn?
That depends on:
- Whether the skin is broken.
- The size and location.
- Whether it can be fully covered.
- Whether the dressing will remain secure.
- The rules of your gym or competition.
- Whether there are any signs of infection.
Do not train with an uncovered open wound.
Do not train when the area is leaking, rapidly worsening or suspicious.
Your desire to finish three more rounds does not outrank the wellbeing of everyone else in the room.
Signs You Should Seek Medical Advice
Speak with an appropriate healthcare professional if the area:
- Becomes increasingly painful.
- Feels hot or swollen.
- Develops spreading redness.
- Produces pus or unusual discharge.
- Develops red streaks.
- Is accompanied by fever or feeling unwell.
- Does not appear to be improving.
- Is deeper or larger than a minor surface abrasion.
You should also seek advice when you are unsure whether a skin problem is mat burn, dermatitis, a fungal rash or another condition.
How to Reduce Future Mat Burn
Wear suitable training clothing
A long-sleeved rashguard and full-length spats may reduce direct skin-to-mat friction during no-gi training.
Improve your movement mechanics
Dragging your feet or knees heavily may create more friction than necessary.
Better technical movement will not eliminate every abrasion, but smoother movement may reduce unnecessary scraping.
Keep your skin from becoming excessively dry
Use gentle shower habits and moisturise dry areas after training.
Check the mats
Damaged, excessively rough or poorly maintained surfaces should be raised with the coach or gym owner.
Do not train through an existing abrasion
Repeated friction on damaged skin can keep reopening the same area.
Frequently Asked Questions
Is mat burn an actual burn?
Mat burn is generally a friction abrasion rather than a heat burn. Friction damages the skin’s outer surface.
Should I put recovery balm directly on open mat burn?
Do not place an ordinary cosmetic balm directly into an open wound unless it is specifically labelled for that purpose. Use it on intact, dry surrounding skin or after the area has closed.
Should mat burn be covered?
Broken skin should be cleaned and covered with an appropriate clean dressing.
How long does mat burn take to improve?
Recovery time varies according to the depth, size, location and whether the area keeps being reopened. Seek professional advice when it is worsening or not improving.
Is every red patch after BJJ mat burn?
No. Skin changes can have many causes. Do not self-diagnose a persistent, spreading or unusual rash.
