“Two-thirds of adults throughout all developed nations fail to obtain the recommended eight hours of nightly sleep.”(Walker, M.2018). Lack of sleep has become a widespread social problem and we are ignoring sleep. The inspiration for Deprivation is based on the experience of me and my friends. The book records the various nightlife of young people. Many people may think that such a life is very interesting, but such a lifestyle will bring many problems at the same time. The book also provides a lot of knowledge about sleep and the dangers of sleep deprivation. I hope that after reading this book, people can better understand sleep and pay attention to this problem that we are neglecting.
