睡眠是動物界生物必備的生存本能。844Please respect copyright.PENANAG5yZkg4Qj1

睡眠不足會影響學習及認知能力,亦被譽為是癲癇發作的其中一項原因。同時間亦有多方面研究證實,長期缺乏睡眠的話,最终會引致狗隻 、老鼠及蒼蠅邁向死亡。844Please respect copyright.PENANAHQo3cb2mHu

(圖2)有研究指出(Ref1),睡眠有助消除大腦裡對神經系統有潛在害處的代謝物。844Please respect copyright.PENANAqq5nhyA5G3
β-amyloid (Aβ)就是其中之一種,是與腦部神經退化症狀有所聯繫的一種蛋白質。844Please respect copyright.PENANAqsKtMjksTs
844Please respect copyright.PENANAZ1euLVu2v2
844Please respect copyright.PENANAbueUkhBgjW
當處於睡眠的時候,腦部Aβ的消除速度將會比日間活動時候快足接近一倍!844Please respect copyright.PENANAD9PHrZIlvk
844Please respect copyright.PENANAEHhr5gWMYh
以上雖是老鼠實驗的結果,但足以引證睡眠其中之一的重要性,替腦部清除日間所積聚的代謝物。844Please respect copyright.PENANA7SdVJgsGh9

(圖3)另外,近日有科學家分析了400項0-12歲人體真實數據後(Ref2),提出了一道重要理論。844Please respect copyright.PENANA2uFC78MJYs

844Please respect copyright.PENANA30z680yoy0
人類在2.4歲前,睡眠是建構大腦各神經細胞連接點的重要時間。844Please respect copyright.PENANAehoYiPyZVc
而2.4歲打後,睡眠則主力負責維護大腦的正常運作。844Please respect copyright.PENANAkoa4UgiITE
844Please respect copyright.PENANAgD0qLoD5Vp
而事實上,在人類2-3歲的時候,其腦袋體積亦將會發展至為成人腦袋體積90%有多。844Please respect copyright.PENANArBTNYkhQfy
844Please respect copyright.PENANAfN3bkiNLzP
換句話說,嬰兒2-3歲前的睡眠時間正是他們發展腦部的黃金時間。844Please respect copyright.PENANAYUo98UFt4e
844Please respect copyright.PENANAS11DircJrl
為子女日後發展著想,我在這裡強烈呼籲各家長千萬千萬不要打擾或吵醒嬰兒們的作息!844Please respect copyright.PENANALC46mjpvv4
