筑波大学の研究グループによる最近の研究によると、日本では平日と休日の睡眠パターンのずれである「社会的ジェットラグ」により、年間約1兆円の経済損失が生じていると推定される。この研究は、睡眠アプリを利用する約8万人の労働者のデータを分析したもので、睡眠パターンと労働生産性の関係を大規模に調べた初めての試みだ。
筑波大学の研究グループは、スマートフォンの睡眠アプリを利用する約8万人の労働者のデータを分析し、社会的ジェットラグが日本経済に与える影響を明らかにした。この現象は、平日と休日の睡眠スケジュールのずれを指し、労働生産性の低下と強く関連しているという。
研究グループは、「睡眠時間だけでなく、睡眠の質や不規則な睡眠スケジュールも労働生産性の低下と強く関連していることがわかった」と述べている。この推定損失額は1兆円に上り、社会的ジェットラグが健康と経済に及ぼす影響を強調するものだ。
この研究は、睡眠パターンと生産性の関係を大規模に探った初の試みであり、平日中心の生活リズムがもたらす問題を指摘している。キーワードとして睡眠、健康、調査、筑波大学が挙げられる。

A new survey reveals that Brazilian workers dedicate an average of 40.1 hours per week to paid work, below the global average of 42.7 hours.
