3 During sleep your body balances and regulates its vital systems, affecting respiration and regulating everything from circulation to growth and immune response.在睡眠期間，你的身體會對各個系統(tǒng)進行調(diào)節(jié)， 你的呼吸，血液循環(huán)系統(tǒng)，免疫系統(tǒng)和身體的成長都會受到影響。

5 A fifth of your body's circulatory blood can be channeled to your brain as you drift off.   在你進入夢鄉(xiāng)的時候，你身體里的五分之一的血液會流入你的大腦。
