Mantra Vitality Log - 捱夜嘅代價：你個腦已經喺「垃圾堆」入面運作緊！ / The Price of Staying Up: Is Your Brain Operating in a "Junkyard"?

《Nature Medicine》及《Science》近三年的研究指出，大腦擁有獨特的「類淋巴系統」(Glymphatic System)，專門在深層睡眠時清除β-澱粉樣蛋白等代謝廢物。如果你每晚瞓少過 6 小時，大腦清除「垃圾」的效率會下降超過 50%，導致毒素堆積。這不單止是第日覺得攰，而是直接提升了兩倍患上失智症 (Dementia) 的風險。在香港，每 10 名 70 歲以上長者就有 1 名患有認知障礙症，而這個「垃圾堆積」的過程早在 30 歲就已經開始。

Research in Nature Medicine and Science indicates that the brain's "Glymphatic System" clears metabolic waste, like Amyloid-beta, primarily during deep sleep. Sleeping less than 6 hours reduces this "trash" clearance efficiency by over 50%, leading to toxin accumulation. This isn't just about feeling tired; it doubles the risk of developing dementia. In Hong Kong, 1 in 10 seniors over 70 suffers from cognitive impairment, and this "waste accumulation" process begins as early as age 30.
