I’ve written a lot about sleep. But when I found this “article” about sleep from 2016— well, at 361 pages, it’s definitely not an “article.” Now that I found this article, I feel comfortable that in recent years I’ve not been writing about sleep. This topic is already well-covered.

And you really should go look at the PDF. Eight-hours a day? —wrong. Same time to-bed/to-rise each day? Wrong. Single-phase, biphase, … it’s all so complicated!

I hope that this article compiles all the basic ingredients of knowledge that are helpful in accomplishing refreshing sleep. As for the sacrifice, it is important to begin with the understanding that one cannot eat one’s cake and have it too. Healthy sleep may be incompatible with some modern habits, some cravings, or some lifestyle choices. At worst, refreshing sleep may be incompatible with one’s job or even long-term goals.
