Some recent literature reports that hot spring baths can treat psoriasis. A hot spring bath is actually a mineral bath, which is a bath, cold bath, rubbing bath and shower with mineral hot spring water, and the temperature of the mineral bath is usually 36℃ to 38℃, and each treatment lasts about 10 to 20 minutes. There are also hot baths with higher temperatures, up to 40°C to 42°C, which are generally used for local treatment. It is reported that the application of mineral bath therapy for psoriasis has a cure rate of 40.2% and a total effective rate of 85%. Therefore, this kind of therapy has a long course, general effect and inconvenient treatment, so it is mostly applied as an auxiliary therapy in recent years. Hot spring therapy also has certain indications, especially hot baths with temperatures over 38℃. For patients in the quiescent and receding stages, mineral baths can remove scales, promote blood circulation, reduce the excitability of nerves and achieve sedation and antipruritic effects, and improve the circulatory status and metabolic process of the whole body, but for patients in the progressive stage, because the body is in a highly sensitive state, bathing can aggravate the lesions due to the hot and cold stimulation of water, and can also occur due to forceful scrubbing and injury to the epidermis and isomorphic reaction, making the lesions The skin lesions can be aggravated by the hot and cold stimulation of water. Therefore, not all psoriasis patients are suitable for mineral baths. Patients in the progressive stage should avoid bathing as far as possible to prevent aggravation of the lesions; while patients in the stationary and receding stages should be encouraged to take mineral baths to help the scales fall off in large quantities and promote blood circulation throughout the body, so as to facilitate early recovery from the disease.
