About the Author

Eddie Bye

Founder, Combat Sports Hygiene · Brazilian jiu-jitsu grappler

I'm Eddie, founder of Combat Sports Hygiene and the person behind these articles. I train Brazilian jiu-jitsu, and the mats are exactly where this whole thing started. After one too many run-ins with the skin problems that go round every gym, I couldn't find a hygiene product built for how grapplers actually train - so we made one.

That lived experience shapes everything we publish here. It's written by someone who trains, sweats and rolls, not a content farm. If a tip wouldn't survive a hard week of sparring, it doesn't go in.

Experience & how we work

• Written from hands-on years training Brazilian jiu-jitsu and around combat-sports gyms.
• Every health claim is researched against trusted public-health and dermatology sources - NHS, CDC, DermNet and the British Association of Dermatologists.
• Health and skin-condition articles are medically reviewed and fact-checked by our medical consultant, Dr Asoka Wijayawickrama.

Medically reviewed & fact-checked by

Editorial standards & review process

How the CSH Hygiene Library is researched, written, reviewed and corrected

The CSH Hygiene Library exists to give combat and contact-sport athletes, parents, coaches and gym owners clear, practical hygiene information. These are the standards every article on this site is held to.

1. Purpose and scope

• Our articles are educational, general guidance. They are not medical advice, diagnosis or treatment, and they never replace a consultation with a pharmacist, GP or dermatologist.
• We write about hygiene routines, kit care, skin conditions that circulate in training environments, and the science of hypochlorous acid and sports soap. We do not give individual treatment plans or dosing advice.
• CSH products are cosmetic hygiene products registered under the UK Cosmetic Products Regulation (the Mat & Gym Floor Cleaner is a surface cleaner, not a cosmetic). Nothing we publish claims that any CSH product treats, cures, prevents or diagnoses any disease or skin condition. Where a product is mentioned in an article, it is as part of a hygiene routine, never as a treatment.

2. Who writes

• Articles are written by Eddie Bye, a combat sports athlete and the founder of Combat Sports Hygiene, from first-hand experience of training in grappling gyms. Each article names its author at the top and at the foot of the page.
• Where a guest contributor writes a piece, their name and role replace the default byline on that article.

3. Sources we use

• Health and skin-condition information is checked against recognised public-health and dermatology references: the NHS, the CDC, DermNet, the British Association of Dermatologists, the American Academy of Dermatology, peer-reviewed literature via PubMed, and the governing bodies of the sports we cover (for example the IBJJF, World Rugby, England Rugby and British Wrestling) for return-to-play and skin-check rules.
• Claims are linked to their source in the text where a reader may want to check them. We do not cite forums, anonymous social posts or other retailers as medical sources.
• We do not take payment for editorial coverage and we do not publish sponsored health content.

4. Medical review

• Articles in the Skin Health and Hypochlorous Acid blogs, first-aid guidance (including turf burn and friction burn care) and the factual content of product pages are reviewed by our medical consultant, Dr Asoka Wijayawickrama (MBBS, MRCS(Eng), MRCGP, GMC 4545590).
• Review means checking that the information is accurate, current and consistent with UK clinical guidance. It does not mean Dr Asoka endorses any product, and it is not personal medical advice.
• Reviewed articles show the month and year of their most recent review beneath the title. Reviews are logged internally so the published date and the review record always match.
• Kit-care, laundry and general gym-etiquette articles that make no health claims are fact-checked editorially and are not medically reviewed.

5. The firewall between education and products

• Skin-condition explainers (ringworm, staph, impetigo, herpes gladiatorum, MRSA and similar) are written to inform. They carry a health notice at the top and a full notice at the foot of the article, and their "Keep reading" suggestions only ever point to other articles, never to products.
• Routine and product-comparison articles may reference CSH products. When they do, the notice on that article says so, and the wording is kept to what the product is: a cosmetic for cleansing and freshening skin.
• Any reader who suspects they have a skin infection is directed to a pharmacist, GP or dermatologist, or NHS 111 in the UK, before anything else.

6. Updates and corrections

• Articles are revisited when guidance changes, when a reader flags an issue, or when a product or rule they reference changes. Material updates change the review date shown on the page.
• If you believe anything on this site is inaccurate, out of date or unclear, contact us with the article URL and the point in question. Reviewed pages are re-checked by Dr Asoka and corrected where needed.

7. Advertising, affiliates and AI

• We do not run third-party advertising or affiliate links in the Hygiene Library. The only products linked are our own, and those links are labelled as such.
• Drafting and research tools may be used to help organise material, but every article is written, checked and signed off by a named person, and medical content is reviewed by our medical consultant before it is published.
