Spring is flu season. Influenza, referred to as influenza for short, is an acute respiratory infection caused by influenza A, B and C viruses respectively. The most remarkable epidemiological characteristics of influenza are: sudden outbreak, rapid spread, wide spread and strong seasonality (the epidemic situation in northern China generally occurs in winter, and it mostly occurs in summer and winter in southern China). The highest infection rate is among teenagers, and the high-risk group is elderly, weak or chronically ill. How to effectively prevent influenza?

First of all, we should have a clear understanding of the flu. An acute respiratory infectious disease caused by influenza virus is called "influenza". It occurs all year round, with high incidence in winter and spring. The infectivity is the strongest in 2-3 days after the first onset, and gradually improves in 3-4 days. It is highly contagious and changeable, with the characteristics of sudden onset, rapid spread, large number of infected people and short epidemic process. Clinical manifestations include high fever, muscle pain and mild respiratory symptoms. Infants and the elderly are prone to pneumonia. Chinese medicine calls flu "seasonal cold" and "sick or angry."

Secondly, we should take a proactive attitude or take effective protective measures. China is rich in TCM health preserving contents. Preventive measures are various and should be considered from the following aspects.

Combination of indoor and outdoor sports

According to the climate, personal physique and time, adopt flexible exercise methods suitable for personal needs. The ancients said, "the fittest is suitable for people." Such as Tai Ji Chuan, Baduanjin and Wuqinxi. And pay attention to the amount of activity also depends on physical fitness, not excessive, excessive counterproductive, the philosopher said: "everything is measured, excessive is not acceptable." Hua Tuo said: "The human body wants to work hard, but it should not be extreme." It is necessary to strengthen the exercise of keeping out the cold, such as washing your nose with cold water. Rub cold water on your upper body. The old man in Ma Yinchu took a bath by alternating hot and cold water, but he lived for a long time and became ill. Pay attention to keep warm in winter, keep the indoor temperature not too high or too low, put on clothes in time when going out, and wear a mask when necessary.

Second, keep the indoor air fresh.

Open the window for ventilation every day, clean it frequently, and keep the indoor environment and personal hygiene. Change your toothbrush frequently, wash your hands frequently, and stay in bed when you have a cold. If possible, live alone in a room and cook vinegar indoors. Don't go to public places to avoid infecting others. Drink more water, rest more, eat some digestible food, and eat more Chinese cabbage, radish, coriander, mutton, onion, ginger and fresh vegetables and fruits in winter and spring. Keep your stomach healthy. Wear a mask when you need to go out with the flu, avoid sneezing with your hands, and don't shake hands with people after the flu. Burn your feet with hot water every night.

Third, keep enough sleep.

Adequate sleep is the basic requirement to ensure the normal physiological function of the human body, and it is the premise to grow energetic and maintain full spirit. If you don't get enough sleep in an unhealthy lifestyle such as staying up late playing cards, your body will be in a sub-health state, and your ability to keep out the cold will naturally decline, making you vulnerable to the flu.

Fourth, don't neglect to keep warm and drink plenty of cold.

When the weather is cold in winter and spring, people don't add clothes in time, which is a common situation in people's lives. It should be pointed out that cold drinks or cold beer should not be used too much in winter. The ancients said, "Drinking cold with cold hurts the lungs." Emphasize neglecting to keep warm, and drinking a lot of cold will hurt the lungs. In winter and spring, special attention should be paid to the insulation of the lower body, and the ankle can be rotated frequently to improve the blood circulation of the lower limbs.

Five, keep emotional peace

Great joy, great sorrow, great fear, great anger, and great earthquake will all lead to the dysfunction of human organs and easily get the flu. In the Qing Dynasty, Li Yu said in My Story: "The sum of heart is the sum of shape." It's about the influence of mentality on health. Chinese medicine says: "When evil is combined, its qi will be deficient." Remind people not only to have a healthy body, but also to maintain an optimistic and peaceful attitude from spiritual cultivation, and pay attention to cultivating healthy qi from both mental and physical aspects, because healthy qi can't hurt people.

6. Rinse your mouth with light salt water to keep your throat clean and prevent the flu from coming in.

Chinese medicine believes that the throat is the portal of the lung, and the lung protects the muscle surface function. It can be seen that throat health care plays a very important role in the prevention and treatment of influenza. If you don't eat spicy things in your daily diet, such as hard liquor and peppers, you should also pay attention to protecting your throat.

Seven, the prevention of influenza drugs

It has a long history in the history of disease prevention in China. Huangdi Neijing, a classic work of traditional Chinese medicine, said: "If you don't treat diseases, you won't get sick. If you don't treat it, it will be chaotic. " It's about the concept of prevention first. For thousands of years, the most commonly used single drugs for treating influenza are Radix Ginseng, Radix Isatidis and Rhizoma Phragmitis. Yang Shitai's Collection of Materia Medica in Qing Dynasty. Guan zhong pointed out in the article: "when the epidemic gas breaks out, put this medicine in water so that people can drink this water, and it will not be contagious."

Chinese medicine divides influenza into three types: simple influenza, pneumonia influenza and toxic influenza. The specific treatment plan after suffering from influenza requires doctors to combine specific symptoms and signs for treatment. Commonly used therapeutic prescriptions include Jingfangbaidu Powder, Huoxiang Zhengqi Powder, Yinqiao Powder, Chaihu Ji Jie Decoction, singa Xiangxie Drink, Chaihu Dayuan Drink, Maxing Shigan Decoction and so on. The Chinese patent medicine has the functions of clearing away plague and detoxicating. Add Zi Xue powder and antelope horn to Jingfeng. The throat is swollen and even purulent, with full phlegm. Use Liushen Pill or Monkey Jujube Powder. High fever coma, Angong Niuhuang Pill, Zhibaodan and Shenxidan all have good clinical effects.

Gargling with black tea can prevent influenza.

Recently, it is popular to gargle with black tea in Japan, and many merchants have also introduced "gargling black tea". In this regard, Professor Shimamura of Showa University School of Medicine agrees. He suggested gargling with black tea to prevent the flu.

Professor Shimamura did an experiment. He divided 300 students into two groups: one group gargled with tea twice a day; The other group did not. Five months later, Professor Shimamura found that the students who gargled were basically not knocked down by the cold virus.

"This is because tea contains catechol," said Professor Shimamura. Catechol is an antioxidant and has a high content in black tea. This substance helps to inhibit the activity of oxygen free radicals in the human body, help the human body resist external viruses and help us stay away from colds. At the same time, catechol in black tea can also inhibit tumor growth.

Professor Shimamura said that studies have proved that black tea with a concentration of 5% can completely kill cold germs. "The concentration of black tea we usually drink is generally between 2% and 5%, which is enough to prevent colds." Professor Shimamura pointed out that the "mouthwash black tea" sold in the Japanese market is basically the same as drinking black tea in composition and concentration, so it can be used with confidence.

"It will be more effective to gargle." Professor Shimamura said that he would gargle once a day after getting up and once a day after returning home. Specifically, put black tea in your mouth 15-20 seconds, then spit it out and repeat it two or three times.

Finally, Professor Shimamura pointed out that not only black tea but also green tea has the same effect. In addition, the higher the quality of tea, the more "tea rust" it contains, and the better the effect of preventing colds. Inferior tea is basically ineffective.
