Earlier, CCTV reported that 300 million people in China had difficulty sleeping, and many people were troubled by insomnia. However, the second sleep may also be a problem. At present, there are more than 700,000 narcolepsy patients in China, who can fall asleep at any time.

Han Fang, director of the Sleep Center of Peking University People's Hospital, said that this kind of sleepiness is different from others. We often talk about uncontrollable sleepiness. Moreover, the characteristic of this kind of drowsiness is that sleeping for one second and sleeping for several minutes or even seconds at the same time will make the mind clear immediately, but not for a while.

There is another feature of this disease. We call it paroxysmal collapse. When we are happy and excited, we lose our strength. Just like electric shock, we suddenly lose strength and even fall to the ground, which is related to emotions.
