To bathe or not to bathe?
For decades, there has been the question as to whether the frequency of bathing or showering has any effect on the extent or severity of atopic eczema.
Some dermatologists advocate infrequent bathing, whilst others encourage regular or daily bathing. The question has never been subject to a randomised trial, and it is a frequent question posed by sufferers.
To address this, a recent randomised control trial of weekly versus daily bathing in atopic eczema was conducted. A total of 438 people with self-identified eczema were randomised between late January and July 2024 in the UK. Minor eczema, hand eczema only, and stasis eczema sufferers were excluded. Patients were over the age of one, with the majority being over 16 years of age.
Patients were randomised into either daily or weekly bathing or showering. Their bathing or showering regime and use of emollients or soap substitutes remained the same as they had used in the lead in period, and no other therapy changes were made during the assessment period. The majority of participants had no preconceived opinion as to whether bathing frequency had an effect on their eczema activity.
A Patient-Orientated Eczema Measurement score was undertaken on a weekly basis over four weeks by the participants.
The trial found no evidence of a clinically important difference in eczema symptoms between those bathing or showering weekly versus daily. There was a slightly reduced use of topical steroids in the weekly bathing group.
The results are helpful as patients with eczema can choose with confidence whichever ablution regime suits them best in terms of convenience and personal preferences without having a significant impact on their eczema.

아토피 치료 가이드에는 매일 통목욕을 짧게 하고 바로 보습제를 바르는 것이 좋다고 돼 있으나
개인적으로는 특히 겨울에는 매일 통목욕을 하면 피부가 너무 건조해지는 거 같습니다. 온몸에 꼼꼼히 보습제를 매일 바르는 것도 사실상 쉽지 않고요.

Water is fine, daily or not. However, soap is the problem for some.

Climate, humidity, pollution matters. In places, like India, it has to be cleaned frequently. and Sun Exposure too needs to taken into account.

The skin needs to be cleansed from sweat, dirt, crusts, pollen and other irritants in order for it to be ready to receive treatment and be hydrated. Bathing regularly is not the problem and should be encouraged as a long as it is a short bath/shower followed by immediate moisturising.

It is hard to believe that so many people in the West bathe or shower once a week, having or not atopic dermatitis. Imagine the skin in the Summer which requires once or twice daily application of topical medications and emollients, layer onto layer, mixed with sweat and dirt. If not so relevant for the atopic dermatitis, this study made me add to any of my treatment plans the recommendation: take a shower once a day.
