(1) Psoriasis patients should pay attention to water temperature and ambient temperature. Water that is too hot (above 40°C/104°F) can irritate lesions and have adverse effects. Water that is too cold (below 34°C/93°F) fails to adequately soften scales and promote skin blood circulation, hindering lesion resolution.Generally, water temperature should be slightly warm or slightly hot to the patient, ideally between 35–39°C (95–102°F). Water temperature can also be adjusted based on lesion type:For lesions in the stationary phase, especially markedly thickened plaque-type lesions, higher water temperatures may be used. Additionally, bathing should be conducted in a warm environment to prevent catching a cold, which could exacerbate psoriasis.Psoriasis patients, if possible, should bathe daily. Medicated baths or mineral baths are even more beneficial. Clinical experience shows that patients who consistently bathe 1–2 times daily for 20–40 minutes typically achieve recovery faster than those using the same medications without bathing.The duration of each bath varies based on the water temperature chosen and the individual's tolerance, generally ranging from 20 to 50 minutes. If the water is cooler and the patient has higher tolerance, the bathing time can be longer. Conversely, if the water is hotter and the patient has lower tolerance, the time should be shorter. In summary, the extent of bathing should be such that it does not irritate the lesions, cause fatigue, or induce discomfort.
(3) Bathing Methods for Psoriasis Patients
Showering is recommended. Avoid excessive scratching of lesions or vigorous rubbing with towels. Experience shows that irritating lesions through scratching or scrubbing often hinders their resolution.
(4) Bathing for Psoriasis Patients with Specific Conditions
For patients with generalized pustular psoriasis, erythrodermic psoriasis, or exudative psoriasis, bathing water should not be too hot to avoid irritating lesions. Additionally, potassium permanganate baths or starch baths are recommended.For elderly or frail individuals, or those with underlying conditions like heart disease or hypertension, bathing should involve lower water temperatures. A seated shower is safer, and bathing should be supervised or assisted by another person.
The above outlines key considerations for bathing in psoriasis patients. We reiterate that bathing requires special attention and should not be taken lightly.
