How to Sleep [1935] avi

Following giving one on how to keep awake, a man holds a lecture on the topic of how to sleep. He plans to separate the lecture into four sections: the cause of sleep, how to induce sleep, methods of avoiding sleep, and how to wake up. He discusses that sleep occurs when blood leaves the brain, and then he talks about several home remedies for that to happen, some having some unintended consequences. Consequentially, he also talks about reasons for insomnia, some unwittingly self-induced. In this discussion, he also talks about why people may wake up in the middle of the night. That last issue also has unintended consequences for his lecture.
