do you by chance have any articles or studies you could link that you've ran across. I tried with google but there's a lot of articles out there that promote exercise. I was told "not to rest too much" by a relative who heard it from a friend who is an anesthesiologist but I didn't follow that advice and instead rested as much as possible. My relative who refused to rest is 3 weeks out from their illness and are still has chest congestion and fatigue so it feels like important information to get to them.
