Abstract: This article creates a fantasy scene called the “Chemical Mediation Room” based on the experiences of three young people—Xiaoyu, Lin Wei, and Zhou Hang—who suffer from persistent physical discomfort caused by poor living habits. The story unfolds around three core themes: the “confusion of pleasure signals” between dopamine and endorphins, the “circadian rhythm dislocation” triggered by disrupted melatonin secretion, and the “mitochondrial dysfunction” closely related to insufficient coenzyme Q10. By integrating the molecular structures, biosynthetic mechanisms, and key physiological functions of these four substances, the article systematically explains the impacts of excessive reliance on instant pleasure, staying up late under high stress, and chronic physical overfatigue on the human body, and puts forward corresponding improvement suggestions. Using anthropomorphic narration to connect scientific knowledge, this article aims to help readers understand the chemical signals sent by the body, and emphasizes that physical and mental balance can be achieved through a healthy lifestyle.
