Hello, my graduation thesis is COVID-19. What should I do if I let go now? What you can do now is to improve your immunity as much as possible. Because immunity is the key to resist and defeat the virus, the body with high immunity can also have higher resistance in the face of epidemic situation, even if it is inadvertently infected, it can effectively reduce all kinds of serious problems caused by diseases. Therefore, in this special period, in addition to daily personal protection, the key is to start with immunity. Eat a balanced diet and maintain a balanced nutrient absorption. The daily body resistance should be based on balanced nutrient absorption. Malnutrition and lack of nutrition will destroy the body's immune system resistance, so if you want to have good immunity, you must eat well in your daily diet. In order to enhance immunity, you can pay more attention to the intake of vitamins C, A, B, E, various minerals, anthocyanins and other nutrients. Drink plenty of water every day. Many people don't have the habit of drinking water at ordinary times, which is a very bad habit. Water plays a very important role in the metabolic detoxification system of human body. In cold winter, water can keep the mucosa of digestive tract and respiratory tract moist and keep the mucosa system healthy, which can effectively help us resist the invasion of bacteria and viruses. Appropriate outdoor exercise, many people are reluctant to go out in cold weather, but it is easy to affect the development of immunity in a closed room for a long time, so usually do more outdoor exercise. In this process, the respiratory system can absorb more fresh air, exercise can stimulate heart and lung function, sun exposure can also play a role in disinfection and sterilization, and promote the development of immunity. Finally, in the face of a completely liberalized epidemic environment, we don't have to be overly alarmed about COVID-19. After all, fighting the virus and maintaining emotional stability is also an important part. Now the toxicity and pathogenicity of the virus are much lower than that of three years ago, so in the face of the epidemic situation after liberalization, we should treat it with normality and do a good job of personal protection.
