Hazards of insufficient sleep:
1. Emotional instability. People who are tired for a long time are emotionally unstable because sleep and mood are regulated by the same brain chemical.
2. Grow old before you get old. Hormone changes during sleep promote skin blood flow, so sleep well and 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 efficiently.
3, the resistance becomes 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 nights in a row have a weaker immune response to the flu vaccine.
4, slow response. Making tea will also spill tea on the new clothes you just bought. So clumsy may be caused by lack of sleep. Dr. Klaette Kushida, director of the Center for Human Sleep Research at Stanford University, said that there is a lot of evidence available at present that people who lack sleep are slow to move, inattentive, unresponsive and have worse motor skills. In addition, drowsiness can also lead to impaired balance and deep perception.
