Hanging neck fan blowing does not necessarily cause facial paralysis in patients, but may induce facial paralysis in some patients with low immunity or have been infected with viruses.
In many cases, facial paralysis is caused by cold and cool wind stimulation. Due to cold stimulation of vasoconstriction, especially in patients with low immunity or infected with viruses, it is easy to lead to ischemia of the facial nerve, edema occurs, leading to narrowing of the facial nerve channel and squeezing of the facial nerve, which leads to dysfunction of the patient.
It is recommended that patients with symptoms of facial paralysis, such as crooked corners of the mouth, inability to close the eyes, and leakage of wind in speech, should consult a doctor in a timely manner, and under the guidance of a professional doctor, the earlier the treatment, the easier it is to obtain the best recovery results.
