From "Dopamine Traps" to "Endorphin-Driven Growth" ——Design Logic, Scientific Foundations and Heilongjiang Implementation Roadmap of Screen-Free Study Tour Camps

While school-based education remains preoccupied with examination scores, a generation of children is undergoing a silent neurological transformation driven by smartphone algorithms. Fragmented attention, cognitive echo chambers, and psychological fragility have become prevalent symptoms. The underlying mechanism lies in the systematic hijacking of the brain's dopamine reward circuitry by the infinite-scroll, instant-feedback design of short-video platforms and social media. Practice-oriented study travel, endowed with irreplaceable natural, physical, and authentic social environments beyond the reach of schools, is uniquely positioned to systematically extract children from the “low-resistance, high-stimulation” realm of virtual gratification and guide them into the “high-resistance, deep-engagement” channel of endorphin-driven flow experiences, thereby achieving genuine mental restoration and character foundation-building. This article clarifies the essential distinction between dopamine and endorphins from a neuroscientific perspective, proposes a curriculum architecture and design principles for “screen-free camps,” and, drawing on the forest, wetland, and agricultural resources of Heilongjiang Province, offers recommendations for pilot camp sites. It aims to provide practical references for practitioners in the field of study travel.
