College students usually have a lot of spare time to do other things, so they don't have to study or play at night often. It is best to go to bed at eleven o'clock and get up at six or seven in the morning. 9- 1 1 pm is the time for the immune system (lymph) to detoxify. During this time, you should be quiet or listen to music.
At night 1 1- in the morning 1, the liver should be detoxified when sleeping. Going to bed too late affects the detoxification of the body, so it is easy to cause constipation and long spots on the face.
