What are the hazards of insufficient sleep? Thank you for your questions.
The harm of insufficient sleep:

1, emotionally unstable. People who are tired for a long time are emotionally unstable because sleep and mood are regulated by the same brain chemical.

2. Get old before you get old. Hormone changes during sleep promote skin blood flow, so sleep is good, skin is brighter and more elastic. Many studies have found that skin renewal at night is 8 times faster than during the day, which can reduce wrinkles more effectively.

3, the resistance is getting worse. People who don't get enough sleep are more likely to get sick. In a foreign study, researchers injected healthy participants with cold virus. It was found that participants who slept less than 7 hours were three times more likely to be infected with cold virus. However, people who only sleep for 4 hours for several consecutive nights have a weak immune response to influenza vaccine.

4. Slow response. Making tea will also spill tea on the new clothes you just bought. Such clumsiness may be caused by lack of sleep. Dr. Collette Kuhida, director of the Center for Human Sleep Research at Stanford University, said that there is a lot of evidence that people who lack sleep are slow-moving, inattentive, unresponsive and have worse motor skills. In addition, drowsiness can also lead to impaired sense of balance and depth perception.
