Why sleep should be every student's priority

In Tamminen’s ongoing research project, participants learn new vocabulary, then stay awake all night. Tamminen compares their memory of those words after a few nights, and then after a week.
Even after several nights of recovery sleep, there is a substantial difference in how quickly they recall those words compared to the control group of participants who didn’t face sleep deprivation.
Clearly, for children as well as adults, prolonged sleep isn’t a sign of laziness in a language learner. It’s critical for our brains’ connections and our bodies’ rhythms.
So, following your next intense Duolingo session, it’s a good idea to sleep on it. You may be surprised the next morning by how much you’ve absorbed.
とくに言語学習なんかには確実に睡眠は重要な模様。昼寝も良いとのこと。
私などは睡眠不足気味、生活リズムぐちゃぐちゃでなおかつ毎日アルコールで脳細胞を殺している。どうりでなかなか異常に記憶力が悪いわけである。
