Introduction
Red, itchy skin can be frustrating—especially if you train Brazilian Jiu-Jitsu, wrestling, judo or MMA.
Two conditions that are often confused are ringworm and eczema. Although they may appear similar at first glance, they have different causes and may require different approaches.
Learning the difference can help you know when to seek professional advice and how to better care for your skin.
What is Ringworm?
Despite its name, ringworm isn't caused by a worm.
Ringworm is a fungal infection affecting the outer layer of the skin. It commonly appears as:
- A circular or ring-shaped rash
- Slightly raised edges
- Itchy skin
- A clearer centre as it spreads outward
Because contact sports involve frequent skin-to-skin contact and shared mats, ringworm can spread more easily in gyms if good hygiene practices aren't followed.
What is Eczema?


Eczema is completely different.
It is an inflammatory skin condition that affects the skin barrier and is not contagious.
Common signs include:
- Dry skin
- Redness
- Flaking
- Cracked skin
- Persistent itching
Many factors may contribute, including genetics, allergies, irritation and environmental triggers.
Key Differences
| Ringworm | Eczema |
|---|---|
| Caused by fungi | Caused by skin barrier dysfunction and inflammation |
| Usually circular | Often irregular patches |
| Can spread between people | Not contagious |
| Frequently seen in contact sports | Common in the general population |
Why Grapplers Should Pay Attention
Combat sports create the perfect environment for skin problems:
- Heavy sweating
- Constant friction
- Shared mats
- Close physical contact
- Damp training gear
None of these automatically lead to skin problems, but they can increase exposure to microorganisms and irritants.
Daily Hygiene Matters
One of the simplest habits athletes can develop is showering soon after training.
A good cleansing routine helps remove:
- Sweat
- Dirt
- Oils
- Dead skin cells
- Residue picked up from training mats
This supports healthy-looking skin and leaves you feeling fresh after every session.
Choosing the Right Soap
When selecting a post-training soap, look for products that:
- Cleanse effectively without excessive dryness
- Contain skin-conditioning ingredients
- Produce a rich lather
- Leave skin feeling refreshed
- Suit frequent daily use
Natural ingredients such as tea tree oil, olive oil, coconut oil and peppermint are popular additions in skincare because they provide a refreshing cleansing experience and help maintain skin comfort.
Final Thoughts
Ringworm and eczema may look similar, but they are very different conditions.
If you're unsure what you're dealing with—or if a rash persists or worsens—seek advice from a healthcare professional.
For athletes, a consistent post-training hygiene routine, clean equipment and appropriate skincare are simple habits that help keep skin feeling clean and comfortable throughout the training week.
