運動で睡眠の質は上がる？10分の運動をする日が多い学生ほど深い眠り
Move Every Day, Sleep More Deeply
1A study in the United States has linked exercise on more days to deeper sleep. Even 10 minutes of exercise a day was linked to better sleep.
2Researchers at the University of Texas at Austin studied 69 students. Their average age was 21.5. The students wore fitness trackers on their wrists. The trackers recorded their exercise and sleep for eight months in total.
3The researchers looked at how often the students exercised. Students who exercised for at least 10 minutes on more days got more deep sleep. In this kind of exercise, you breathe harder, but you can still talk.
4Light movement, like walking or standing up for short breaks, was also linked to better sleep. More deep sleep was linked to a better mood and more energy the next day.
5The study shows a link, but it does not prove a cause. The team is now planning a five-year study with more kinds of people.

全文訳
1アメリカの研究で、運動する日が多いほど眠りが深い、という関係が見つかりました。1日10分の運動でも、よい眠りと関係がありました。
2テキサス大学オースティン校の研究者が、69人の学生を調べました。学生たちの平均年齢は21.5歳でした。学生たちは、手首に運動を記録する機器をつけました。その機器が、合わせて8か月のあいだ、運動と睡眠を記録しました。
3研究者たちは、学生がどのくらいの回数で運動したかに注目しました。10分以上運動した日が多い学生ほど、深い眠りが多くなっていました。ここでいう運動は、息は上がるけれど、まだ話ができるくらいのものです。
4歩いたり、少し立ち上がって休けいしたりする軽い動きも、よい眠りと関係がありました。深い眠りが多いと、次の日の気分がよく、元気も多くなっていました。
5この研究でわかったのは「関係がある」ことで、運動が原因だとまでは言えません。研究チームは今、いろいろな人を対象にした5年間の研究を準備しています。
文法ポイント：関係代名詞 who（人を説明する）
who のあとに文を続けて、前の「人」を説明する。本文の Students who exercised for at least 10 minutes on more days got more deep sleep. は「10分以上運動した日が多い学生は、深い眠りが多かった」。who から days までが Students を説明している。
