4. "daydreaming is Tin" Song: Kong
You can sit back and relax when you are busy. Four branches of wine are strong in spring, and the wind blows lonely dreams like clouds. Why not be quiet when all the students are reciting strings?

Going to bed late is a form of sleep that seriously exceeds the normal time to get up. Now, it mostly happens among working people and students. Because of the hard work and study, they often catch up on sleep on weekends, but overloaded sleep will cause sub-health of the body.
Hazards of staying up late:
Sleeping late will disrupt the physiological rhythm. Normal people's endocrine and the activities of various organs have a certain day and night law. This biological law regulates people's various physiological activities, making people energetic during the day and sleeping well at night.
If you sleep late on holidays because of the law of life, it will disrupt the circadian rhythm in the body and make endocrine hormones abnormal. If this continues for a long time, you will be depressed and depressed.
Sleeping late will affect gastrointestinal function. Breakfast is usually around 7 o'clock. At this time, the food for dinner has been basically digested, and the gastrointestinal tract will contract due to hunger. People who love to sleep late would rather be hungry than get up early for breakfast. After a long time, they are prone to chronic gastritis, ulcers and indigestion.
Sleeping late will affect the excitability of muscles. After a night's rest, my muscles relaxed more in the morning. Getting up immediately after waking up can aggravate muscle blood circulation and increase blood supply, which is conducive to muscle fiber thickening. However, people in bed are in a state of relaxation for a long time, with poor muscle repair and metabolites not eliminated in time. After getting up, they will feel weak legs and waist discomfort.
