Using light exposure strategically to support natural, consistent energy throughout the day.
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.
