The harm of irregular sleep time for middle school students

Nowadays, people's living conditions have improved, and lack of sleep has become a widespread phenomenon among primary school students today. Lack of sleep is very harmful to health, so don't take it lightly. So, the hazards of abnormal sleep time for middle school students are mainly reflected in the following aspects?

1. Influence on creative thinking of the brain Researchers once divided 24 college students into two groups and asked them to take a test first. The results of the two groups were the same. Then, one group of students was asked to stay awake overnight, while the other group slept normally, and then they took the test. The results showed that the test scores of students in the no sleep group were significantly lower than those of students in the normal sleep group. Therefore, researchers believe that if the human brain is to think clearly and react quickly, it must have sufficient sleep. If there is a lack of sleep for a long time, the brain will not get enough rest, which will affect the brain's creative thinking and ability to handle things.

2 Modern research shows that factors affecting the growth and development of adolescents include genetics, nutrition, exercise and other factors, as well as the secretion of growth hormone. Growth hormone is a hormone secreted by the hypothalamus that promotes the development of bones, muscles, and internal organs. Because the secretion of growth hormone is closely related to sleep, that is, there is a large secretion peak after a person falls asleep, followed by several small secretion peaks, while in the non-sleeping state, the secretion of growth hormone decreases. Therefore, if teenagers want to develop well and grow taller, they must get enough sleep.

3. The reason why human skin is soft, smooth and shiny is that it relies on the capillaries in the subcutaneous tissue to provide sufficient nutrition. Lack of sleep can cause stagnation of skin capillaries and obstructed circulation, making it impossible for skin cells to get adequate nutrition, thus affecting skin metabolism, accelerating skin aging, and making the skin appear dull and pale. Especially the eye circles become dark and wrinkles easily appear.

Through the above simple introduction to the main hazards of abnormal sleep time for middle school students, I believe everyone has their own answers to the questions in their hearts. The reminder here is: you need to get enough sleep every day. Good sleep quality is very important to the human body. Lack of sleep is extremely harmful to the body and directly affects physical health. We must develop good sleeping habits in our daily lives, try our best to control and improve our sleeping conditions, and having a good sleep quality is the beginning of all things.
