The first thing to do when you are sick is to receive treatment in time. Besides receiving treatment, we should also pay attention to rest. However, whether you can exercise after getting sick and whether it will have side effects on your body depends mainly on the patient's condition. If you still have symptoms such as cough after treatment on your side, I suggest that you don't do strenuous exercise in the short term. Because you are in the stage of weak immunity, exercise will only reduce your immunity, you will become weaker, make you feel short of breath, nausea and even vomiting, and the recovery time will be extended again! If your illness allows you to exercise reasonably, then it is recommended not to go to the gym before recovery, because the environment of the gym is mostly closed, and poor ventilation will affect your recovery, but it will have a bad influence.
