A 2021 Tools for Practice1 notes that for atopic dermatitis (AD), more frequent baths (and likely showers), 1-2 times/day, improve symptoms meaningfully (≥30%) for about 40% more patients than less frequent bathing (with moisturizers after bath/showers).
Despite advocacy, research does not support bleach baths, bath additives or water softeners for AD symptoms.
Offer simple advice for frequent plain-water bathing and application of moisturizers immediately afterwards. The bleach baths advice is also contrary to advice on the Auckland Health Pathways. Clinical discretion is advised.
