Eczema and the Skin Microbiome: What Gym Hygiene Can—and Can't—Do
Skin naturally hosts many microorganisms. Researchers are studying how these communities interact with atopic dermatitis, but “microbiome-friendly” claims can go beyond what any one study proves. You can care for your skin and practice good gym hygiene without trying to sterilize your body.
What NIH researchers studied
In research described by NIAMS in 2023, investigators examined the genetic diversity of skin bacteria in people with atopic dermatitis and identified strains and genes associated with disease presence or severity. This is an evolving research area; the study does not show that a particular moisturizer kills bacteria or treats infection.
| Situation | Practical next step |
|---|---|
| Your skin | Cleanse gently as needed and follow your dermatologist's eczema plan. |
| Shared gym equipment | Follow facility cleaning guidance and allow surfaces to dry before use. |
| Towels and open containers | Keep personal items personal; CDC advises against sharing towels or ointments from open containers. |
| Possible infection | Pain, increasing warmth or swelling, pus or fever deserve prompt medical assessment. |
Clean equipment, not skin with disinfectant
CDC recommends cleaning shared athletic equipment and following disinfectant labels. These products are intended for surfaces; do not apply them to skin or wounds. Handwashing and a post-workout shower when practical are different from using harsh surface cleaners on your body.
Skin microbes, atopic dermatitis and infection are related areas of research but are not interchangeable diagnoses. Do not start, stop or share antibiotics based on a skin-care claim. Ask your clinician about signs that concern you.
