Fan hats do not necessarily blow facial paralysis on the face, but prolonged exposure to cold air may induce facial paralysis in some patients with low immunity or viral infections.
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 viral infection, it is easy to lead to ischemia of the facial nerve and edema occurs, resulting in narrowing of the facial nerve channel and squeezing of the facial nerve, causing the patient to develop dysfunction.
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.
