Certain water treatments are helpful in cases of tuberculosis. The patient's vital resistance can be built up by a carefully planned graduated cold bath routine twice a day. The intensity of the cold applications should be gradually increased to achieve satisfactory results. However, care must be taken to keep the patient from catching a chill. A short hot fomentation with alternate short cold application to the chest and back, and in the stomach region or a neutral immersion bath (water temperature 98 to 100º F) for an hour just before retiring at night is also beneficial.
