Key ideas in Hacking Your Brain: A User's Manual
- Viewing sunlight within the first hour of waking triggers a cortisol release for alertness
- Caffeine blocks adenosine receptors rather than clearing adenosine out
- Light through a window is significantly less effective than direct outdoor light for setting the clock
- Natural cortisol levels are already high upon waking and drop after 90 minutes
- Morning light exposure determines when melatonin will be released later that night
- Delaying caffeine allows the brain to naturally clear sleep-inducing chemicals so they don't flood back in later
- The timing and mechanism of using sunlight to regulate the circadian rhythm
- The relationship between caffeine timing and adenosine buildup
- A double inhale re-inflates the air sacs in the lungs
- A long, slow exhale through the mouth signals the brain to slow the heart rate
- The brain's resistance to a task is usually highest in the first few minutes
- The technique works by offloading carbon dioxide rapidly
- Committing to just 10 minutes tricks the brain into starting by lowering the perceived 'cost' of the effort
