我为什么要在一本谈论排忧的书里写有关避免疲劳的问题呢？原因很简单，因为疲劳常常会带来烦恼，至少会使你容易感到烦恼。任何一个医科学生都会告诉你，疲劳会降低身体对普通感冒和其他上百种疾病的抵抗力。任何一位心理学家都会告诉你，疲劳会降低你对恐惧和烦闷的抵抗力。所以，避免疲劳有助于避免忧虑。
我刚才是说“可以避免忧虑”吗？这句话表达得缺少力度。芝加哥大学实验心理学实验室主任埃德蒙·雅各布解释得更明确一些。他写了两本有关放松的书——《消除紧张情绪》和《放松紧张情绪》。多年来，他一直在临床实践中运用放松紧张情绪的方法，并进行了相关方面的研究。他声称，任何精神或是情绪的紧张状态“在完全放松的状态下就会消失”。换句话说，如果你处于放松状态，就不会再忧虑了。
所以，为了避免疲劳和忧虑，第一条规则就是：经常休息，在你感到疲倦之前休息。
