我承認,在學生時代養成的”夜貓子”生活習慣,到現在還無法完全改過來,一部份也是因為哄小孩睡覺之後,才有自己的時間,這麼寶貴的時段,往往不想太早結束,所以就弄到蠻晚才睡的,結果今天看到這一篇研究報導,著實讓人心生警惕……
2015年4月1日韓國的研究,發表在The Journal of Clinical Endocrinology & Metabolism,在前言中,就已經提到幾個關於夜貓子的研究,會如何影響健康:
1. 夜貓子的睡眠時間通常比較短,早上還沒到生理時鐘該起床的時候,就因為得上班,而縮短了生理所需求的睡眠時間。
2. 而睡眠時間較短,容易導致肥胖、以及糖尿病的發生。
3. 再者,睡眠時間縮短,容易使糖尿病患者的血糖控制變差。
4. 夜貓子的生活型態,得到糖尿病的機會升高為2.5倍。
因此,他們找了1620個中年人,年紀在47-59歲之間,先發問卷問他們:幾點會覺得累、幾點起床、幾點是你覺得最有精神的時候,把他們分成:夜貓族、早睡一族、以及不特別早或晚的族群。結果發現夜貓族會……:
1. 三酸甘油脂(triglyceride)比較高。
2. 發炎指數(hsCRP)比較高。
3. 體脂肪比較多。
4. 男性的糖尿病風險,升高為約3倍 [OR:2.98 (95% CI, 1.39 – 6.39)]。
5. 女性的代謝症候群風險,升高為約4倍 [OR:3.89 (95% CI, 1.33–11.33)]。
所以囉!早點睡吧,各位!
