Answer 1

When you are ill your body contains a high amount of disease-causing bugs. When you exercise you are making blood flow at a higher rate. This means the bugs end up in places where they normally wouldn’t be. This is especially a problem with viral diseases. If you exercise the virus will likely end up in your heart. A viral infection in your heart causes it to swell up, which causes all kinds of problems.

EDIT: Wow damn. It feels like I insulted Ghandi himself rn.
