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。975Please respect copyright.ＰＥＮＡＮＡfOXGe0xen0

（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。975Please respect copyright.ＰＥＮＡＮＡz59zg3Fo0P
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。975Please respect copyright.ＰＥＮＡＮＡnJ1kl8Qcft

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!975Please respect copyright.ＰＥＮＡＮＡqOmJ4gCXME

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。975Please respect copyright.ＰＥＮＡＮＡKSXxUXYgHg

（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。975Please respect copyright.ＰＥＮＡＮＡdBSq55TS54

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。975Please respect copyright.ＰＥＮＡＮＡVx3MSWlgdO
而2.4歲打後，睡眠則主力負責維護大腦的正常運作。975Please respect copyright.ＰＥＮＡＮＡmK1PSdSpgw

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。975Please respect copyright.ＰＥＮＡＮＡx5b3GPn1j3

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。975Please respect copyright.ＰＥＮＡＮＡfXluOKi223
975Please respect copyright.ＰＥＮＡＮＡ5ydmLXdeIG
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!975Please respect copyright.ＰＥＮＡＮＡLHNr2bSKn6
