Who knew sleep did so much for us? It actively restores our health, reduces cancer rates, boosts our immune response, and makes us more social, improves our coordination and alertness, and makes us smarter (yes, your cognition decreases when you haven’t slept enough). It also helps us manage our emotions and one phase of sleep even helps us increase our creativity (hence why we often say we’ll “sleep on it” when we can’t seem to find clarity in a problem). It’s truly a wonder drug, so it’s a terrifying thought to think that we are living in a world of sleep deprivation.

[I received a copy of this book through NetGalley.] It took me so long to get to this book (which I also requested late, it didn’t help), and I’m wondering why! Although it *was* definitely scary, it was really interesting—and anyway, the ‘scare’ makes a lot of sense, so I wouldn’t be inclined as to consider it ‘alarmist stuff I can probably safely ignore because all these doctors and scientists write alarming stuff anyway’. I’ve had trouble to sleep for decades—while not a full night own, I’m clearly not a lark either, and this is part of my problems—and let’s be honest, it doesn’t take a genius to realise that on periods when I sleep less than 6-7 hours/night, I feel sluggiosh, fall sick more easily, stay sick longer, and am less focused in general. Considering my natural chronic lack-of-attention-span disorder, you can guess what it looks like. (And now I’m wondering how much of this attention problem was really related to my Tourette’s, and how much was actually due to not sleeping enough... considering that when tics are flaring while in bed, well, falling asleep becomes an issue, too!) Mostly what the author mentioned makes sense to me from a layman standpoint. Not enough sleep leads to increased risks of car crashes, due to microsleep attacks: yes, definitely, I almost went through that, and when I had to assess the risk of falling asleep at the wheel on a French motorway vs. stopping in a parking lot along that same motorway at 4 am to catch a couple of hours of shut-eye... Let me tell you, no argument about ‘it’s dangerous to be a female being alone at night in a deserted place’ would have made me keep driving. That was a scary, scary moment: feeling that I was falling asleep, and having those two or three seconds of complete inability to react, before I regained control of my body and managed to pull out. Yes, it was that bad. And I was extremely lucky that time. So I was definitely willing to consider Walker’s research in earnest, and not with my usual rolling-of-eyes at ‘alarmist books’. Now, I also understand why my ageing parents are chronically tired, to the point of crashing on the sofa for a long nap every afternoon, yet can’t sleep most of the night. And why I’m going the same way, with the difference that for now I can’t afford to nap due to being at work. Naps reset the build-up of ‘sleep pressure’, and this affects in turn the moment when you’d get naturally tired in the evening, pushing it back by a few hours. (Also, now I get why melatonin pills don’t work for me: apparently I’m not old enough yet. XD) In short, I finally got to understand a lot of things about sleep, which in turn will help me—I’m the kind of person who needs to ‘do’ and ‘understand’ in order to acquire and retain knowledge and act upon it, so this was actually perfect for me. Now I now what happens while we sleep, all the waste it helps our bodies get rid of, why sleep deprivation affects our emotions and moods, and many more things. It’s not a self-help book—while it does have an appendix with a few ‘tips and tricks’ about how to sleep better, don’t expect to see only that for two hundred pages or to find miracle cures—but it’s already doing a lot for me, just thinking about it.

I have read many books on sleep; however, I never learned as much as I did with Why We Sleep. If you are going to read only one such book, this is the one. Though I would have appreciated more self-help information is some places.

Amazing book! I just started getting back into reading and I didn't want to put the book down. After reading the book, I can confidently educate my kids why nap time is good for them and the benefits they will get from sleep. There are many more interesting facts with the research to back them up! Great book to reference back to!
