Poor sleep is a "youth killer"

Long-term lack of sleep will disrupt the biological clock, cause endocrine disorders, and ultimately lead to insomnia, abnormal body metabolism, and easily cause cardiovascular and cerebrovascular diseases.

According to relevant research, lack of sleep will affect skin health, make people older, dumber and fatter, reduce the body's immunity, and cause as many as 84 diseases such as diabetes and cancer. It is an "invisible killer" of human life and health.

In addition to health, sleep also has a great impact on learning. Xiao Chen often feels eye fatigue, headaches and dizziness, and has difficulty concentrating in class. "Sometimes I feel my brain is 'unable to work' or I feel like I'm 'missing a string' that day." Before an exam, she stayed up late to read. During the exam, she felt like her brain was "short-circuited" and she almost fell asleep. As a result, she did very badly on the test. She regretted it and said, "It's not good to 'forget food and sleep' like this. It's better to get a good night's sleep than to 'cram' before the exam."

The professor analyzed that poor sleep can lead to neurasthenia, abnormal emotions, overreactions, and some strange thoughts. More seriously, it can even lead to extreme behaviors such as suicide.
