The probability of numbness is that the trigeminal nerve in the face is dysfunctional after being exposed to cold, resulting in abnormal sensations in the face.
If you blow on the air conditioner for a long time, the sensory nerves of the trigeminal nerve of the face may be damaged, and then the function is abnormal, and abnormal sensations such as numbness and pain may occur. It is important to avoid air conditioners blowing directly on the face or fans blowing directly on people.
In addition if the face is blown against the air conditioner for a long time, there is even the possibility of inducing facial neuritis, leading to peripheral facial paralysis. At this time, the mouth will be crooked, drooling, eyes closed incomplete and other symptoms. At this time, it is necessary to go to the hospital in time, by receiving hormones, antiviral drugs and other treatments, to avoid leaving the sequelae of facial paralysis.
When taking a cool ride in summer, the temperature of the air conditioner should be appropriate and not too low, especially taking care not to have the air outlet blowing directly at the person. If the numbness of the face persists, it is recommended to seek medical treatment as soon as possible and standardize the treatment under the guidance of professional physicians to avoid delaying the condition.
