筑波大学研究小组最近的一项研究估计，日本因“社会性时差”——工作日与假期睡眠模式的差异——每年遭受约1万亿日元的经济损失。该分析基于约8万名使用智能手机睡眠应用的劳动者数据。这是首次大规模考察睡眠模式与劳动生产率之间联系的研究。
筑波大学研究小组分析了约8万名通过智能手机应用追踪睡眠的劳动者数据，揭示了“社会性时差”对日本经济的影响。这一术语描述了工作日与假期睡眠模式的差异，该研究将其与劳动生产率下降密切相关。 该小组表示：“不仅睡眠时长，睡眠质量和不规律的睡眠时间表也被发现与劳动生产率下降密切相关。”他们的估计显示，日本每年经济损失约1万亿日元。 作为首次大规模研究睡眠模式与工作产出之间联系的研究，它突显了以工作日为主导的作息带来的问题。关键词包括睡眠、健康、调查和筑波大学。
