Mantra Vitality Log - 挨夜嘅代价:你个脑已经喺「垃圾堆」入面运作紧! / The Price of Staying Up: Is Your Brain Operating in a "Junkyard"?

2026年4月22日

《Nature Medicine》及《Science》近三年的研究指出,大脑拥有独特的「类淋巴系统」(Glymphatic System),专门在深层睡眠时清除β-淀粉样蛋白等代谢废物。如果你每晚瞓少过 6 小时,大脑清除「垃圾」的效率会下降超过 50%,导致毒素堆积。这不单止是第日觉得攰,而是直接提升了两倍患上失智症 (Dementia) 的风险。在香港,每 10 名 70 岁以上长者就有 1 名患有认知障碍症,而这个「垃圾堆积」的过程早在 30 岁就已经开始。

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.
