Abstract:This article develops the term "media prophylaxis" to analyze the ways technologies are applied to challenges of calibrating one's body with its environment and as defenses against endemic, human-made harms. In recent years, self-illuminated screens (like those of computers, phones, and tablets) have been identified by scientists, journalists, and concerned individuals as particularly pernicious sources of sleep-disrupting light. By tracing the history of circadian research, the effects of light on sleep patterns, and the recent appearance of software like "f.lux," Apple's "Night Shift," and "Twilight," this article shows how media-prophylactic technologies can individualize responsibility for preventing harm while simultaneously surfacing otherwise ignored forms of chronic suffering.

媒体预防：夜间模式和预防伤害的政治

摘要：本文提出了“媒体预防”一词，以分析技术如何应用​​于根据环境校准人体的挑战，以及防御地方性人为伤害的方法。近年来，自发光屏幕（如电脑、手机和平板电脑的屏幕）已被科学家、记者和相关人士确定为特别有害的睡眠干扰光源。通过追溯昼夜节律研究的历史、光线对睡眠模式的影响以及最近出现的“f.lux”、Apple 的“Night Shift”和“Twilight”等软件，本文展示了媒体预防技术如何实现个性化预防伤害的责任，同时出现否则会被忽视的慢性痛苦形式。
