Why We Sleep, Matthew Walker, 2018

The book explores the vital role sleep plays in our physical and mental well-being, explaining the science behind sleep cycles and how various factors like caffeine, alcohol, and light exposure affect our sleep quality. Walker emphasizes the importance of both REM and NREM sleep for memory consolidation, creativity, and overall health, offering practical advice on how to optimize sleep routines for better performance and well-being.

Top 3 Learnings:

1. The circadian rhythm is individualized, and understanding your own “sweet spot” for sleep timing, such as exposure to sunlight, is key for better rest.
2. REM sleep is crucial for processing emotions and enhancing creativity, while NREM sleep focuses on physical recovery and immune function.
3. Alcohol disrupts REM sleep, making it counterproductive for creative work. It’s best to avoid drinking in the evening if you want to tap into your creative potential.
