Rain’s Sanctuary: An LMT Analysis of the Author’s Rain Affinity — Multi-Sensory Natural Phenomenonization and the Optimal Environment for Introspection —

This paper analyzes the author’s lifelong affinity for rain through the framework of Load Minimization Theory (LMT: L = U + F + E). Rain creates an optimal introspective environment by simultaneously reducing cognitive and physiological load across multiple senses: auditory (pink noise), olfactory (petrichor), and tactile (cool, moist air). From the author’s kindergarten days wearing a raincoat and observing puddles, through middle-school corridor moments, to adult café sessions by rainy windows, rain consistently provides a “zero-switch” state where prediction error drops near zero and deep thinking naturally emerges. This study frames rain affinity not as mere preference, but as a beautiful alignment between the brain-body system and nature’s inherent load-minimization mechanisms.
