In addition, do you find that a person with good sleep usual do not have acne, because enough sleep balance their internal secretion and detox. Knowing the importance of enough sleep, do you still stingy about sleep? Do you still dare to sleep late?

充足睡眠是很重要的，它影响到我们是否快乐。很容易发现如果我们晚上睡饱了，第二天我们通常都是好心情的。但是，如果我们晚上睡不好，第二天有时候就会无缘无故的郁闷。而且，睡眠也会影响到我们的学习或者工作。试想一下，一个困乏的人如何听课，如何工作。肯定很难且效率低。所以，如果一个人睡饱了，他可以让他生活的方方面面都变得更好。再者，你有没有发现睡眠质量好的人通常都是很少长痘的，因为充足的睡眠可以平衡他们内分泌并排毒。知道这些后，你还会对睡眠吝啬吗？你还敢晚睡吗？
