Physical therapy for allergic rhinitis includes nasal irrigation, localized hot compresses, infrared short wave therapy and so on. 1. Nasal rinsing method: it is a simple method commonly used in daily life, and the concentration of hypertonic saline or physiological saline below 2.3% is usually used. It can flush the nasal secretion cleanly and help to keep the nasal cavity moist. 2. Local hot compresses: morning and evening hot water fumigation or hot towels can be used to apply hot compresses to the nose to promote nasal blood circulation. 3. Infrared or short-wave therapy: irradiation can improve the local blood supply situation, so as to reduce the symptoms. If the physical effect is not good, you should go to the regular hospital for examination.
