近些年，我们经常会听到人们说起“亚健康”这个词，说是现在大多数上班族都或多或少有些亚健康状态，而且多是压力太大引起的。可是，有研究发现人在缺少压力的情况下，身体也是会不舒服的，这种状态叫做underload syndrome¹，你听说过吗？

Underload syndrome refers to ill health or depression caused by a lack of challenges or stimulation² at work.

动力不足综合症（underload syndrome）指因为工作上缺少挑战或动力而出现的身体欠佳或抑郁的状态。

Boredom³ has exactly the same effect on the body as stress. People who lack stimulation in their working lives are likely to be depressed⁴ and suffer from "underload syndrome". The most common health complaints triggered by underload syndrome are headaches, fatigue⁵ and recurrent infections; it is also a cause of mild depression.

无聊和压力对身体产生的影响是一样的。工作上缺少动力的人有可能会表现得抑郁，还可能会患上“动力不足综合症”。该综合症最常见的病征有头痛、疲劳以及多发性感染，它还有可能引发轻度抑郁。
