Sleep is one of the most important aspects of our life, health and longevity and yet it is increasingly neglected in twenty-first-century society, with devastating consequences: every major disease in the developed world - Alzheimer's, cancer, obesity, diabetes - has very strong causal links to deficient sleep.

Until very recently, science had no answer to the question of why we sleep, or what good it served, or why its absence is so damaging to our health. Compared to the other basic drives in life - eating, drinking, and reproducing - the purpose of sleep remained elusive.

Now, in this book, the first of its kind written by a scientific expert, Professor Matthew Walker explores twenty years of cutting-edge research to solve the mystery of why sleep matters. Looking at creatures from across the animal kingdom as well as major human studies, Why We Sleep delves in to everything from what really happens during REM sleep to how caffeine and alcohol affect sleep and why our sleep patterns change across a lifetime, transforming our appreciation of the extraordinary phenomenon that safeguards our existence.

This book was amazing. It feels cliché to say "life-changing", but it wouldn't be wrong. It was also horrifying. The book highlights the importance of sleep, but I never would've thought that it was that important. I'd dare say it's more important for us than food or water, especially considering that you would be hard pressed to eat or drink if you weren't rested enough to remember how to chew/swallow. Just losing an hour regularly is enough to wreak havoc on your immune system and set you up for Alzheimer's even if it isn't likely to run in your family. I started reading the book in hopes of learning why I have, as the book has taught me the term of, sleep-maintenance insomnia and how to help with it. I walked away with more information about sleep than I ever thought possible, but very few ideas on how to actually tackle it outside of therapy. You will learn how to tackle normal sleep, but severe insomnia like I suffer from is another story.

I was impressed with the writing. You would think that a doctor would leave you with a dull book that would drone on and on with technical terms that would leave you looking up every third word in a dictionary. That wasn't the case. The writing was informal, as far as doctor-speak goes, and easy to follow. Every technical term is defined naturally within a sentence or two.

I didn't walk away with the answers to the questions I had, but I did walk away with a panic attack and a strong determination to focus on the sleep schedules of myself and my children to get us all sleeping better. It also helped me to see the importance of sleep for my children and made me all the more thankful that we homeschool, because I can work our school schedule around their need for rest. I've been focusing on my schedule in the week since finishing this and am already reaping the benefits. Now if only I can get my husband on board with his schedule. I can't get him to read, but maybe if I buy the audiobook he can listed to it on his commute and become just as horrified at what he's doing to himself as I am. I don't care how much he insists that he can survive on 5 hours of sleep regularly, this book proves otherwise.

Could you walk away with a summary and be alright? Sure. But I would still recommend reading it anyway. It's such a fount of information that it would be a shame to walk away without it. If you really want to skip out and just work on getting better sleep, then all you need is the 12 steps in the back of the book. It's all fairly common sense, but it's the bare minimum you take away from it.
1. Stick to a sleep schedule
2. Don’t exercise too late in the day
3. Avoid caffeine & nicotine
4. Avoid alcoholic drinks before bed
5. Avoid large meals and beverages late at night
6. Avoid medicines that delay or disrupt your sleep (where possible)
7. Don’t nap after 3pm
8. Make sure to leave time to relax before bed
9. Take a hot bath before bed
10. Have a dark, cool (in temperature), gadget free bedroom
11. Get the right sunlight exposure
12. Don’t stay in bed if you (really) can’t sleep
