From the Research
Cold showers are not recommended for treating pityriasis rosea, as they have not been proven effective for this condition. Pityriasis rosea is a common, self-limiting skin rash that typically resolves on its own within 6-8 weeks without treatment. For symptom relief, lukewarm baths or showers are generally better than cold ones, as extreme temperatures (either hot or cold) may irritate the skin and potentially worsen itching.
Treatment Options
If you're experiencing discomfort from pityriasis rosea, over-the-counter antihistamines like diphenhydramine (Benadryl) or cetirizine (Zyrtec) may help reduce itching, as suggested by 1. Topical treatments such as calamine lotion, hydrocortisone cream (0.5-1%), or moisturizers can also provide relief.
Medical Interventions
According to a recent study 2, acyclovir represents the best option for patients with PR that have extensive, persistent lesions or systemic symptoms. Steroids and antihistamines seemed the best treatment for itch resolution.
Additional Considerations
Mild to moderate sun exposure has shown some benefit in certain cases, though this should be approached cautiously to avoid sunburn. If your symptoms are severe or persistent, consult a healthcare provider who might prescribe stronger anti-inflammatory medications or other treatments specific to your situation. The exact cause of pityriasis rosea remains unknown, though it's believed to be triggered by a viral infection, which explains why symptomatic treatment rather than specific cures is the standard approach, as noted in 3 and 4.
