The Science of Sleep and Dreams

You spend a third of your life asleep, yet most of what happens in those hours stays a mystery. Why do you wake at 3 a.m., and where do dreams actually come from?

This lively science audiobook follows your brain and body through a single night, in commute-sized chapters made for listening. You ride the sleep cycles from light dozing to deep sleep and REM, watch your brain file the day's memories, and meet the overnight cleaning crew that clears waste while you rest. Every number arrives with an everyday analogy, so the science sticks. Each chapter closes with a calm look at what researchers know and what they are still working out, plus gentle takeaways on caffeine, evening light and how sleep changes as you age.

Afterwards, bedtime feels less like switching off and more like a busy night shift you finally understand. Press play on your next drive or walk and meet the night you've been sleeping through.
