The BrainSpan Protocol
Peak Mental Performance for Knowledge Workers
You used to be sharp. Focused for hours, quick to connect ideas, able to hold complex problems in your head and work them through. Now the brain fog rolls in by 2 PM, your attention fractures after fifteen minutes, and you cannot remember whether that was a good idea or just caffeine talking. You are not aging out. You are burning out, and the fix is not another productivity app.
Rachel Keene spent 15 years in a circadian biology lab studying how the brain sustains high performance. The BrainSpan Protocol distills that research into a structured daily system for knowledge workers: sleep architecture that actually restores cognitive function, nutrition timing that fuels focus instead of crashing it, movement protocols calibrated for mental clarity, and attention management strategies grounded in how working memory actually operates.
Every chapter ends with a specific, evidence-based protocol you can start today. No supplements, no gadgets, no miracle hacks. Just neuroscience that works.
