Sleep Sweeps Neurotoxic Wastes from the Brian 睡眠時腦部進行排毒

一項發表在「科學」(Science)的研究指出,人類的腦部會利用睡眠時排毒,以清掃腦部垃圾。人腦運作時,無法在清醒時同時進行覺察和清理,如同家裡辦派對,無法同時招待賓客又打掃房子。如果腦部排毒不徹底,部份有毒的蛋白質(protein)會殘留在腦部,可能造成腦部疾病,這也說明了睡眠的重要性。

A study published in Science Journals points out that human brain may drive metabolite clearance from the brain during sleep.  The human brain does not function simultaneously in awareness and clearance when it is awake.  It is like when having a party at home, one cannot welcome the guests while sweeping the house.  If the metabolite wastes are not removed completely, some potential protein may remain in the brain which would probably cause the brain disease.  This suggests the importance of sleep.
