With the general acceleration of people's life rhythm, lack of sleep has become a common phenomenon among urbanites today. Experts remind that lack of sleep is very harmful to health, so don't wait and see. The harm of insufficient sleep is mainly reflected in the following aspects:
1. Affect the creative thinking of the brain
A researcher once divided 24 college students into two groups and asked them to take a test first. Results The test scores of the two groups were the same. Then, let one group of students stay up late, the other group sleep normally, and then take the exam. Results The test scores of students without sleep were much lower than those of students with normal sleep. Therefore, researchers believe that a person's brain must have enough sleep to think clearly and react sensitively. If the brain does not get enough rest for a long time, it will affect its creative thinking and ability to deal with things.
2. Affect the growth and development of teenagers.
Modern research believes that the growth and development of adolescents is related to the secretion of auxin in addition to genetic, nutritional and sports factors. Auxin is a hormone secreted by hypothalamus, which can promote the development of bones, muscles and organs. Because the secretion of auxin is closely related to sleep, that is, there is a big secretion peak after people fall asleep, and then there are several small secretion peaks, while in the non-sleep state, the secretion of auxin decreases. Therefore, teenagers should develop well, grow tall and get enough sleep.
3. Affect skin health
The reason why human skin is soft and shiny is that it relies on the capillaries of subcutaneous tissue to provide sufficient nutrition. Lack of sleep will cause blood stasis in skin capillaries, and the circulation will be blocked, so that skin cells can not get enough nutrition, which will affect skin metabolism, accelerate skin aging and make skin look dull. Especially the eyes are black and prone to wrinkles.
4. cause disease.
Frequent lack of sleep can make people feel anxious and reduce their immunity, which can lead to various diseases, such as neurasthenia, colds, gastrointestinal diseases and so on. A Swedish medical researcher found that lack of sleep can also increase the cholesterol content in the blood, thus increasing the risk of heart disease. An Australian research society suggested that cell division in the human body is mostly carried out during sleep, and lack of sleep or sleep disorder will affect the normal division of cells, which may lead to the mutation of cancer cells and lead to cancer. Generally speaking, people of different ages need sleep every day. Middle school students should sleep 8-9 hours a day, and adults should sleep 7-8 hours a day.
