In the face of the daily weather in spring in Beijing, is it disturbing to say that the "Wind is getting cold and the face is getting paralyzed? Although from the clinical experience, there are many cases of wind and cooling history before the onset of facial paralysis, it is currently considered that these are only the cause and do not prevent wind damage as a means to prevent facial paralysis. You don't have to be too nervous about the cold air.

Rumor: Weibo-[take off winter clothes too early and be careful with facial paralysis !] There is a saying in the People's Republic of China: spring and autumn are frozen, and all kinds of diseases are ignored. According to Metropolis Express, because I didn't pay attention to keeping warm, the water in the mouth of a girl in Hangzhou suddenly flowed out unconsciously while brushing her teeth. A mirror showed that one side of her face was paralyzed. The doctor said that there have been a lot of facial paralysis patients recently, but they don't pay attention to the heat. The girls who love beauty don't worry about taking off their winter clothes!
Truth: It's a terrible thing to catch a face in the cold. Although from the clinical experience, there are many cases of facial paralysis that have a cold history before onset, especially the cold wind in the narrow gap, it is currently believed that the cold wind is only the cause. In textbooks, it is not mentioned to avoid wind energy to prevent facial paralysis.
What is facial paralysis?

Strictly speaking, facial paralysis is a symptom. The face on one side of a patient loses the ability to control his or her facial muscles, and his or her facial expression is distorted and cannot be controlled. In rare cases, there will be both sides of the disease [1]. Some facial paralysis symptoms have clear causes, such as Ramsay-Hunt Syndrome and Lyme disease, but most Facial Paralysis (80%-90%) the cause of the disease is unknown. It is called Bell's palsy and also known as facial paralysis. (generally, there are three words in a disease that indicate the cause is unknown ). It can only be diagnosed by the exclusion diagnostic method, that is, it can be diagnosed only after the possibility of all other diseases is ruled out [2].
Why does it face paralysis?

From the pathology, facial paralysis is caused by problems with facial nerve. The facial nerve grew and wound, and left behind the skull to walk in a narrow bone-shaped neural tube. Because the facial nerve canal can only accommodate the facial nerve passage, once the facial nerve has inflammatory edema (not only edema, but also nerve detachment and severe nerve axis cable degeneration ), it will inevitably lead to facial nerve oppression, and clinical facial paralysis will occur.
The cause of facial nerve edema is unclear. There are some hypotheses, such as virus infection (HSV-1, herpes zoster virus, etc.) may be related to this pathological change, or because of the instability of autonomous nerve function caused by local nutritional nerve vascular cramps, this results in facial nerve ischemia and nerve edema. However, these hypotheses are still not proven. [3] [4]
Will it face facial paralysis when it gets cold?

According to the clinical manifestations, there are many cold cases before the onset of facial paralysis. The cold air in the narrow gap is a common cause. Most people find the side of the face ineffective during early morning washing. However, it is not mentioned in textbooks that we should avoid facial paralysis caused by wind energy.
In addition, in the international research on beishi facial paralysis, various types of emotional stress and environmental stress, including trauma, cold, metabolic disorder, and emotional disorder, they are all considered to have induced beishi's facial paralysis [5], but they have not been directly linked to beishi's facial paralysis. At the same time, the study also found that there is no seasonal difference between the beam facial paralysis, and there is no seasonal alternation or more prone to onset in the strong wind season [4].
How to Prevent facial paralysis?

Unfortunately, it is still unclear about the cause of illness that makes it impossible to prevent beishi's facial paralysis. The good news is that its incidence is not very high (only two thousandths), and 2/3 of patients can recover naturally within three weeks even if they do nothing after the onset. Only a small number of people will leave sequelae, such as chronic lack of taste and sudden onset of facial muscle spasm. Some particularly unlucky patients may permanently lose the facial muscle scar function and affect their life [6]. In addition, young people naturally have a higher chance of healing than the elderly.
at the same time, there is also a lack of special drugs and treatments for facial paralysis. Currently, hormone therapy, antiviral therapy, and B vitamins are commonly used. Practice has proved that these methods have some effect in reducing symptoms and accelerating recovery, but the effect is not very significant [7]. Widely used acupuncture and electro-acupuncture treatments and face movements in China may be effective, but no research is supported. In addition, there are some controversial treatments, such as electrotherapy, botulinum toxin injection, and surgical treatment. These treatments are not recommended and can only be used if other methods are ineffective.
In addition, facial paralysis may lead to loss of closed eyes. Pay special attention to eye protection. Use artificial tears and eye ointment to keep the cornea moist. You can also use a wet towel or eye mask to cover your eyes at night to prevent exposure keratitis.
conclusion: we do not know much about this problem. At present, we only believe in experience that wind and cooling are only the cause, not the decisive factor of the disease. Textbooks and related research literature do not mention preventing facial paralysis from wind energy. You don't have to be too nervous about the cold air. However, medicine is still empirical science, and many diseases are not fully understood. Although I do not think that catching cold is the root cause of facial paralysis, it is correct to keep warm.
