【 #識嘢】睡眠真係可以「預先儲定」?
成日話「瞓唔夠要補眠」,但你有冇聽過「睡眠儲蓄」?即係預先瞓多啲,等之後要捱夜或者瞓得少嘅時候,可以「拎返出嚟用」?
美國一項研究將軍人分成兩組:一組每晚瞓7個鐘,另一組瞓10個鐘,之後所有人每晚只可瞓3個鐘。結果發現:提前瞓多啲嗰組,即使後期嚴重缺乏睡眠,警覺性同專注力下降幅度較少,而且恢復速度亦較快。
後來,不少帆船選手同職業運動員都採用呢個方法,為身體預先「儲定睡眠」。
神經學教授解釋,大腦同身體每日都會累積代謝廢物,而睡眠正正係大腦清除廢物嘅關鍵時間。因此「睡眠儲蓄」就係為大腦預留更多清洗時間,同時補充能量儲備,應付之後出現嘅睡眠不足。
所以如果知道自己嚟緊要通頂趕 deadline,不妨試下預先「儲定啲睡眠」!
We often hear people say, “if you don’t get enough sleep, you can catch up later.” But have you heard of “Sleep Banking”?
Sleep Banking means having more sleep in advance so that your body can draw on those reserves from the bank during periods when you are deprived of sleep.
In a U.S. study, soldiers were divided into two groups. One group slept 7 hours a night, while the other slept 10 hours. Afterwards, everyone was allowed to sleep for 3 hours in other nights. Those who had banked extra sleep hours showed a smaller drop in alertness and focus and recovered faster.
Since then, many sailors and professional athletes have adopted this strategy to help their bodies prepare for periods of insufficient sleep.
A neurology professor explains that our brains and bodies accumulate metabolic waste every day, and sleep is the key time for the brain to clear this waste. In this sense, sleep banking gives the brain extra time to perform this “clean-up” process while also replenishing its energy reserves.
So, if you know you'll be staying up late to meet a deadline, try getting some extra sleep beforehand! 😴💤
