The child lacks energy and is always sleepy. Why?

Patient's question:

I had acute nephritis last year, but it has been cured after treatment. A few days ago, my cold got better. Now I just feel weak and keep feeling sleepy. A week

Doctor's answer:

Don't worry, relax. It's recommended that you have a light diet and go to bed earlier at night. Suggestions: It's best to go to sleep by 10 p.m. because 12 a.m. to 5 a.m. the next morning is the optimal time for the liver to detoxify. Moderate exercise is also essential, such as a 40-minute walk after dinner, which is particularly beneficial.
