The eczema home environmental audit — room by room

The home environment is the one you spend the most time in and the one you have the most control over. A systematic room-by-room audit, addressing the main trigger categories in each space, is often the most impactful single action in the early phase of eczema management.

This is the audit included in the XmaHub protocol. It's structured to address the most common and highest-impact environmental triggers first.

The bedroom

The bedroom is the highest priority because you spend a third of your life there and the allergen load in bedding is typically the highest in any room.

Allergen-impermeable covers — mattress, duvet, and pillow — with a pore size of 6 microns or less. These are available from pharmacies and specialist suppliers. Wash all bedding weekly at 60°C. Remove any soft toys that aren't washable at 60°C — these are significant mite reservoirs. Consider replacing carpet with hard flooring; if this isn't possible, vacuum weekly with a HEPA-filtered vacuum and damp-mop rather than dry-sweep.

Set a maximum bedroom temperature of 18°C. Monitor humidity with a hygrometer; aim for below 50%. If humidity is consistently higher, a dehumidifier is worth the investment.

Check your nightwear — is it 100% cotton or silk? Check the washing detergent, and ensure an extra rinse cycle is being used.

The bathroom

The bathroom is where your skin comes into contact with the most direct chemical irritants.

Replace all fragranced products — soap, shower gel, shampoo, conditioner, shaving products — with fragrance-free alternatives. Check ingredient lists rather than front-label claims. Use lukewarm water, not hot. Limit baths and showers to 10–15 minutes. Pat dry rather than rubbing.

Check the emollient — is it ceramide-containing? Is it being applied within three minutes of drying? Is it being applied in sufficient quantity?

If you have hard water, test a vitamin C shower filter or consider a water softener assessment.

The kitchen

The kitchen's relevance to the environmental audit is mainly about cleaning products. Washing up liquid, surface sprays, and other cleaning products often contain fragrances and preservatives that irritate compromised skin. Switch to fragrance-free, dye-free alternatives. Wear gloves for any prolonged contact with cleaning products or water — dishwashing is a common trigger for hand eczema.

Check the washing-up gloves themselves — latex is a common allergen; nitrile is a safer choice.

The laundry

Laundry detergent and fabric softener are covered in detail in the dedicated article. The key points: fragrance-free and dye-free detergent, extra rinse cycle on all washes, no fabric softener.

Pets

Pet dander — skin flakes and saliva proteins from cats, dogs, and other animals — is a significant allergen in some eczema cases. If you have pets and have never removed them from your environment for a sustained period, it's difficult to know whether they're contributing to your eczema. The protocol doesn't require rehoming pets, but keeping them out of the bedroom and washing your hands after contact is a reasonable starting point.

HEPA air filtration reduces airborne pet dander significantly. Running a HEPA air purifier in the rooms where you spend most time is worthwhile if pets are present.

Work environment

The environmental audit doesn't stop at home. If you work in an environment with significant trigger exposure — a hospital, a hairdresser, a kitchen, a construction site — occupational triggers may be contributing. Nitrile gloves rather than latex, barrier creams before occupational exposure, and thorough emollient application after work are the key occupational interventions.
