短视频应用通过特定的神经学机制对用户形成强大吸引力。1快速的视觉切换和精准的算法推送激活了大脑的奖赏回路，促使其释放多巴胺，产生强烈的愉悦感和期待感。1与此同时，这种推送方式还会削弱大脑前额叶皮层的功能，而前额叶正是负责冲动控制和行为约束的关键脑区。1两个因素的叠加形成了成瘾的闭环。
北京回龙观医院成瘾医学中心主任杨可冰指出，判断是否陷入"上瘾"状态有两个关键信号：快感来源的单一化，以及对刷屏行为的失控。1本身具有"成瘾素质"的人以及处于抑郁情绪中的人群更容易受到影响。1短视频成瘾会导致注意力不集中、记忆力下降，对正常工作学习造成显著影响。1
在未达到成瘾程度时，可以通过转移注意力和参加户外活动等方式自我调节。1但当成瘾现象严重时，需要主动寻求医院成瘾科等专业机构的帮助。1
Short-form video platforms exploit the brain's reward system through rapid visual transitions and algorithmic precision, triggering dopamine release and creating a cycle of addiction, according to experts at Beijing Hui Long Guan Hospital's Center for Addiction Medicine.1 The fast-paced content delivery weakens the prefrontal cortex's ability to control impulses, the region responsible for behavioral restraint and decision-making.1
Director Yang Kebing of the addiction medicine center identified two critical indicators of problematic use: when pleasure becomes narrowly focused on a single source, and when viewing becomes uncontrollable.1 Individuals with addictive predispositions or those experiencing depression are particularly vulnerable to developing compulsive viewing habits.1 Short-video addiction can impair concentration and memory, disrupting work and academic performance.1
Those not yet at addiction levels can manage their usage by redirecting attention or engaging in outdoor activities.1 However, severe cases require professional intervention from hospital addiction specialists.1
