Usually, after vaccination, if there are no adverse reactions such as redness, swelling, pain and weakness at the vaccination site, as well as nausea and vomiting, then you can play basketball such as proper shooting, but it is not recommended to play strenuous sports on the day of vaccination to avoid intense confrontation. At the same time, after vaccination, adequate rest and nutrition should be maintained. Playing basketball and other strenuous sports can cause accelerated blood circulation and enhanced metabolism throughout the body, which may affect the immunization effect of the vaccine or cause adverse reactions after vaccination, especially swelling and pain at the vaccination site. In addition to playing basketball, strenuous exercise that consumes a lot of physical strength and causes accelerated blood flow, such as playing soccer, swimming, jumping rope and working out, is also not recommended on the day of vaccination. When patients recover their strength and have recovered from adverse reactions, they can gradually resume their normal exercise habits, but they also need to pay attention to their breathing during exercise and seek medical attention if symptoms such as panic, chest tightness, dizziness, nausea, and abnormalities at the vaccination site occur. Patients are advised to clean their skin promptly after about 30 minutes of exercise, when breathing is stable, heart rate has recovered, and sweat has evaporated, and to replenish sufficient water. In addition, personal protection should also be done after vaccination with the new crown vaccine. You should wear a good mask when going in and out of public places, disinfect and clean your hands well, and avoid traveling to areas at high risk of the outbreak. The windows of your home should be frequently opened and ventilated to exchange fresh air and reduce the amount of indoor bacteria, and disinfect your home regularly.
