The weather is turning cooler and it’s the best season of the year in Beijing again. Coinciding with the 60th anniversary celebration, together with the Mid-Autumn Festival, a total of eight days of vacation, everyone is overjoyed and preparing for vacation from now on. Vacation is good, but it is necessary to remind the problem of disease prevention. I remember that once in the National Day on duty in the outpatient clinic, continuously received more than 10 patients with facial paralysis, all acute onset of the disease, ask the medical history, are continuously staying up all night, or get-together, or play cards, a few days without a normal rest. The emergence of this situation is not accidental, Chinese medicine, “positive energy storage, the evil can not be dry; the evil of the gathering, its gas must be weak”, is the truth. The human body in the lack of positive qi, vulnerable to the intrusion of external evil, and wind and cold external evil, is the main pathological factors leading to facial paralysis. Under normal circumstances, the human body is a layer of positive weather barrier to protect the normal physiological activities of people, Chinese medicine called “Wei Qi”, lack of sleep, irregular diet, these factors will lead to the dissipation of human Wei Qi, the barrier will also disappear. Therefore, the festive season is approaching, should emphasize the regularity of living and eating, do not overwork or overeating, especially do not sweat when the wind, to avoid getting cold, so as to reduce the occurrence of facial paralysis.
