That's good. I know they say kind of treat it like the flu. Rest but stay active as pneumonia is often the fatal part of the flu. With Covid it was blood clots in the lungs but also
When SARS-CoV-2 infects lung tissue, it spreads rapidly and may affect the epithelial cells lining the airways. The immune system responds by releasing cells that cause inflammation in the affected tissues.
When this inflammatory immune response continues to happen, it inhibits the regular transfer of gases, including oxygen, in the lungs, and fluid can build up.
So the best way to try and prevent blood clots and fluid in the lungs is to stay mildly active. Even at night. I have heard of people getting up every 2 hours just to move around some.
