寝ている間に脳内の有害な老廃物を洗い流すglymphatic system。
先週、タイ、ベトナムに行っていたとき、平均睡眠時間は4時間。そうしたら、週末どっと疲れが出た。
その後、土曜、日曜と8時間睡眠に戻すと、一気に体調が復活。ジェフ・ベソスさんも睡眠は必ず8時間取るという。やはり自分も、睡眠は8時間は必要なよう。
なお、2012年ロチェスター大学の研究者ネーデルガード氏などが、人は深い眠りについている間に脳内の有害な老廃物を脳脊髄液で洗い流すglympathic systemを発見。つまり睡眠がないと、老廃物が蓄積してしまうという。
やはり、人間にとって、睡眠は間違いなくすべての健康の大元。今後どこに行っても、睡眠の時間だけはしっかり確保することに努めよう。

The glymphatic system flushes out toxic waste from the brain while sleeping.
When I was in Thailand and Vietnam last week, I slept an average of four hours. Then I felt tired weekend.
Then, when I returned to eight hours of sleep on Saturday and Sunday, my physical condition was restored at once. Jeff Besos also says that he always gets eight hours of sleep.I also need eight hours of sleep.
In 2012, University of Rochester researcher Nedelgaard and others discovered that while people are in deep sleep, the glympathic system flushes out harmful waste in the brain with cerebrospinal fluid. In other words, without sleep, waste accumulates, they say.
After all, for humans, sleep is undoubtedly the mainstay of all health. Wherever I go anywhere, I should strive to ensure that I get enough sleep.
