About This Guide

Light exposure is one of the most powerful, least-used levers for natural energy — it directly regulates the internal clock that governs alertness and sleepiness far more than most people realize. This guide covers using it deliberately.

Inside: morning light exposure and why timing matters more than duration, avoiding the evening light exposure that quietly undermines the next day's energy, adjusting light exposure for shift work or limited outdoor access, and building light into an existing daily routine easily.

Includes quick-reference cheat sheets and tool/template checklists (print version), AI-powered prompts at the end of every chapter, and clickable links to Claude and ChatGPT in the digital version. Available in print (8.5×11, binder-ready) and digital (6×9, phone-optimized) formats. Instant download after purchase.
