Core Viewpoint - The phenomenon of "brain rot" emerges as a significant concern in the digital age, highlighting the cognitive decline and brain function damage caused by excessive smartphone use, particularly among youth [1][2]. Group 1: Physiological Impact - "Brain rot" manifests in various physiological damages, such as dopamine overstimulation leading to a thinner prefrontal cortex, which affects decision-making and self-control [2] - Blue light exposure from nighttime smartphone use inhibits melatonin secretion, disrupting sleep rhythms and hindering brain cell repair and memory consolidation [2] - Sedentary behavior associated with prolonged smartphone use decreases levels of brain-derived neurotrophic factor, negatively impacting cognitive function [2] Group 2: Emotional and Social Consequences - Excessive internet use can lead to attention deficits, severely affecting learning and daily life, while a lack of real-world social interactions may trigger depressive symptoms and potentially lead to mental health disorders [2] - The symptoms of "brain rot" are not irreversible; with the reconstruction of healthy habits, the brain can regain its elasticity [3] Group 3: Recommended Interventions - Establishing clear boundaries for digital behavior is essential; families and schools should collaborate to create smartphone usage rules, such as limiting daily entertainment internet time and designating "no screen" periods [3] - Strengthening alternative cognitive training through traditional reading, family dialogues, and logic games can help rebuild sustained thinking abilities in youth [3] - Implementing a sleep protection plan is crucial, which includes banning electronic devices one hour before bedtime to promote melatonin secretion and ensure high-quality sleep [3]

Core Viewpoint - The article explores the philosophical implications of physical experiences in the age of AI and virtual reality, emphasizing the importance of real-world experiences for personal growth and cognitive development [2][5]. Group 1: Physical Experience and Cognition - The article highlights that human brain's spatial cognition is uniquely developed through real walking experiences, which cannot be replicated by VR technology [3]. - It discusses the contrast between digital experiences and the tangible challenges faced in extreme environments, suggesting that the lack of physical engagement may lead to a decline in risk assessment abilities [3][4]. Group 2: Personal Challenges and Growth - The author recounts a personal extreme challenge of completing 100 marathons in 100 days, illustrating the physical and mental transformations experienced throughout the journey [4]. - The completion of this challenge is presented as a form of spiritual and physical dialogue with nature, reinforcing the idea that humans are inherently suited for running and physical activity [4]. Group 3: The Role of Walking in the AI Era - The article posits that walking and travel have evolved into strategies for resisting digital alienation and reconstructing cognitive practices, linking individuals back to nature [5]. - It concludes that the essence of human dignity in the AI era lies in the imperfections of real-world experiences, contrasting with the perfection of digital environments [5].
