Autumn and winter are the seasons with high incidence of colds, and it is particularly important to "focus on prevention" of colds. 1.

Therefore, it is necessary to insist on washing your face with cold water to enhance the adaptability of nasal mucosa to air. Keep abreast of weather changes and add clothes to keep out the cold according to the weather. At the same time, strengthen physical exercise, enhance the ability to adapt to the environment and the body's immunity. In addition, during the cold epidemic, try to go to crowded places as little as possible and wash your hands frequently. When you feel a little sick, dry mouth and stuffy nose, take medicine immediately, drink plenty of water, keep warm and rest, so that your condition can get better in time. 2. Family prevention: pay attention to the fresh indoor air, and open the window for ventilation for not less than fifteen minutes in the morning; If flu patients are found at home, they should be fumigated with vinegar in time for air disinfection. In addition, smearing garlic liquid on healthy people's nostrils or taking a few cloves of garlic orally can also reduce infection. 3. Reasonable diet: garlic, green onions, ginger, vinegar, etc. Are commonly used foods to prevent colds. If the whole body aches and coughs, you can take the prescription of reconciliation and health care (pear, jujube, ginger and crystal sugar boiled to wash eggs), once in the morning and once in the evening, and rest after taking it. Or take onion ginger soup to sweat and dispel cold, and the general symptoms can be alleviated. If the symptoms are serious, medication should be taken as soon as possible to control the development of the disease. 4.
