The main reasons why hot compresses are recommended for rhinitis patients are as follows: 1. When rhinitis patients apply hot compresses, the temperature and the stimulation of the heat will cause the nasal mucosa blood vessels to dilate and the blood flow to speed up, thus reducing nasal congestion and nasal secretions, which is beneficial to rhinitis recovery. 2. The reason why rhinitis patients do not take cold compresses is because the nasal mucosa is very sensitive to cold. Once there is the effect of cold air will lead to more obvious congestion of the nasal mucosa, more obvious edema of the nasal mucosa, increased exudation of secretions, and even easy to induce sneezing and other related performance. In short, patients with rhinitis are recommended to take hot compresses instead of cold compresses. If the patient is in a post-surgical state of rhinitis, local cold compress treatment can be done early in the surgery, and cold compresses have the effect of relieving nasal pain.
