The more you open the humidifier, the drier your throat clinically, there are mainly the following reasons: First, it is a serious laryngitis, so open the humidifier to increase the humidity in the house, but laryngitis itself is not actively treated, so laryngitis is not treated will become more and more serious, open the humidifier is only auxiliary, in the end there is no effect clinically is not very precise. The second, the humidifier makes the air circulation more obvious, so that the airborne viruses, bacteria spread faster, it is easy to be inhaled by the patient oropharynx leading to the aggravation of laryngitis, because the onset of laryngitis and viral, bacterial infection may have a certain relationship. So for patients with laryngitis with a humidifier must be applied only at the same time as treatment, if not for treatment with a humidifier effect is not obvious, in addition to some of the pneumonia, bronchitis, with a humidifier to pay proper attention.
