You can work out the day after the vaccination, but you should pay attention to the intensity of the exercise. In particular, avoid overly strenuous exercise, such as basketball and soccer, to avoid excessive sweating and fatigue, which may cause discomfort and make it difficult to distinguish between discomfort caused by exercise and adverse reactions caused by the vaccination. If you need to exercise, you can do moderate exercise according to your body condition, and choose relatively gentle exercises such as jogging, rope skipping, swimming, light yoga, stretching, etc. However, if you have adverse reactions to the vaccine, such as fever, fatigue, headache, muscle pain, etc., you should rest more and start exercising again after the symptoms have subsided. In addition, during exercise, it is also necessary to avoid sweating and getting cold to avoid catching a cold, which may also easily lead to the appearance or aggravation of adverse reactions after vaccination. Moreover, if the injection site of New Crown vaccine has not fully recovered, sweating may contaminate the injection site and cause secondary infection. In addition, after the vaccination, you need to pay attention to exercise and diet. Make sure to take rest time, get enough sleep, and avoid staying up late or being overly tired. At the same time, until the skin at the vaccination site recovers, it is necessary to ensure that the area is clean and dry, and avoid scratching or contamination. After vaccination, drink plenty of water, eat a light and easy-to-digest diet, avoid drinking alcohol, and avoid spicy and stimulating foods such as chili, curry, raw garlic and ginger to avoid pain and discomfort at the injection site. Those with allergies also need to avoid seafood to avoid allergic reactions.
