It is often said that we live in a 24/7 society: 24 hours, 7 days a week. And with this they want to show that we live looking at the clock in a continuous productive activity. This term applies mainly to the field of business. But how does the dream manage society 24/7? Well, this social structure takes very little into account the dream, it does not contribute anything to the force that moves society forward, and in some cases it annoys you. This idea faces the results of the latest sleep research and what these two books tell.
Experts agree that sleep is not a mere physical disruption of daily activity. German biologist Till Roenneberg relates the dream to the inner clock of people and from there he writes the book Internal Time. "This book is dedicated to watches. It has not been bought on clocks that you can hang on the wall, but on those that tic-t inside your body," Roenneberg wrote in the book's foreword.
Many questions must be answered. For example, if you consider that very active people in the morning are good workers and on the contrary, useless. But this idea is very debatable. Also, how many hours do you need to sleep? Napoleon said that the man takes six hours, the woman seven and the one who sleeps eight hours is foolish. But Einstein slept ten hours. So, what is the most suitable schedule? Is it for everyone?
Roenneberg analyses these and many other issues (cultural, social jet-lag, etc.) in his book on the inner clock. This work has been exhibited in the lists of the best scientific books of 2012.
Another interesting book about sleep is Steven W. Lockley and Russell G. Sleep Neurologists Foster: A very short introduction. In fact, it is a book from the Very Short Introduction collection of Oxford University Press, a brief presentation of several topics. Lockley and Foster's book talks about the sleeping brain, the importance of sleep for health, how sleep occurs and the opposite. It also analyzes the causes of sleep need. Finally, 24/7 reflects on the relationship between society and sleep. It is a good quick reading book.
