First of all, the most important thing is to rest. Adequate sleep can make physical strength recover better, so how long is it appropriate to sleep? In fact, everyone's sleep time is not fixed. It used to be said that the ideal state is to sleep for 8 hours every day, but the details vary from person to person. A simple way to judge is: if you don't feel tired the next day after sleep, then you probably have enough sleep time.
Second, pay attention to diet, drink more water and increase nutrition. We can add some kinds of meat and vegetables, including various fruits, to enrich nutrition, supplement protein, sugar and, more importantly, vitamins, and improve our body's resistance.
Third, we should take appropriate activities. Do what you can, such as walking and tai chi. Because after being infected, people's physical recovery is fast and slow. Some people recover quickly and may start exercising earlier, while others recover slowly. Maybe a healthy body will make people live longer and then start exercising later. It should be adjusted according to personal circumstances, and strenuous exercise should not be carried out just after turning.
