Why We Sleep
Matthew Walker
I wish I’d read this book years ago. I used to treat sleep as negotiable, something to cut when life got busy. I thought I was being productive, but in reality, I was robbing myself of the very thing that makes productivity, clarity, and emotional stability possible. Matthew Walker changed that completely. Why We Sleep is packed with research but it is so clearly explained that you don’t need a science background to follow it – and once you do, you will never look at sleep the same way again.
What convinced me the most was learning what sleep does. Non-REM sleep acts like a neural cleaning crew, clearing out toxins, strengthening memories, and restoring learning capacity. REM sleep, meanwhile, helps us process emotions, build creativity, and connect
ideas in ways we can’t while awake. Miss either, and your brain and body start to fall apart in slow motion.
Walker also shows how sleep deprivation increases the risk of everything from depression to heart disease and even weakens your immune response. Why We Sleep shifted my priorities, and it is essential reading if you care about your health, your brain, or simply being more yourself.
