It is recommended that strenuous exercise should not be performed until about 1 week after the New Crown vaccination. This is to avoid the superimposition or confusion of symptoms such as discomfort, muscle aches, and weakness caused by strenuous exercise just after the New Crown vaccine with symptoms such as weakness and muscle aches that may occur after the New Crown vaccination, which is not conducive to the timely detection and treatment of adverse reactions to the New Crown vaccine. In addition, the human body needs sufficient rest after the New Crown vaccine to help the vaccine response produced by the New Crown vaccine in the human body, which in turn produces protective antibodies, etc. If strenuous exercise is performed at this time, the human body may become tired and fatigued, which will affect the immunity of the human body and the effect of the New Crown vaccination. Therefore, you can gradually increase the amount of exercise after 1 week of vaccination, and avoid high-intensity exercise directly after the vaccination to prevent damage to the body. In addition, low intensity exercise, such as walking, jogging, stretching, yoga, tai chi, etc., can be performed within 1 week after the vaccination, avoiding strenuous running, jumping and various ball games to avoid excessive fatigue of the body, which may induce or aggravate adverse reactions to the vaccine. It is also necessary to eat a light diet, drink more water, avoid drinking alcohol and eating spicy and stimulating food or seafood for 1 week, and ensure sufficient sleep to facilitate the immune response to the vaccine. It is also necessary to pay attention to personal protection on a daily basis, wear a mask when going out and avoid staying in places where people gather as much as possible, which is beneficial to human health.
