I learned a lot from Why We Sleep, by Matthew Walker, and it was compelling enough to change some of my behaviors. (e.g., I spent a week giving myself a full eight hours in bed, taking advantage of the additional early AM flexibility afforded me during WFH times.) Walker makes the complex concepts easy to digest, and the reading was enjoyable. Portions were redundant, especially when describing the setup of every single study, but those were easily skimmable. Worth a read.
