You've tried all the popularremediesfor stress, but you're stilljitteryand tense. Perhaps there are some things causing you stress that you didn't even know about. Here are some surprising factors that can be adding to your stress:

已经尝试过很多解压妙方，可还是容易紧张不安？或许存在某些“诱压因素”，而你却不曾察觉吧。下面这些事情就很可能会加重压力：

Noise:Exposing yourself to loud noises can wear on you because it activates¹ your flight-or-flight response, triggering higheradrenalineand blood pressure, says author A.J. Jacobs in his book Drop Dead Healthy: One Man's Humble² Quest For Bodily Perfection. Jacobs cites a study that compared kids at a public school who studied in quiet settingsversusthose who were in classrooms that heard a train go by every five minutes. Those in the quiet setting were one year ahead in reading by the sixth grade. Another study showed that people who worked at noisy jobs had two to three times the heart problems than those who worked in quiet environments. If we're hearing loud noises all day long, our mind and body will keep activating³ the fight-or-flight response, which means we don't get the much-needed downtime.

嗓音：A.J.雅各布斯在《杜绝致命因素：追求完美健康》中写道：“尖锐的噪音对人体大有危害，它能诱发“战斗或逃跑反应”，使肾上腺素和血压增加。雅各布斯还引用了如下试验研究：一组学生在安静的学校学习，另一组学生每隔五分钟就能从教室里听到外面火车经过的噪音，对比发现，到六年级时，第一组学生的阅读能力明显领先一年。另外还有研究表明，在嘈杂环境工作的人患心脏病的风险是在安静环境工作的人的2-3倍。如果整天面对尖锐噪音，人体会不间断地出现“战逃反应”，一刻不得安宁。

Your friends:Who you spend time with has a huge effect on you, including your mental, physical, and emotional health. In fact, Jacobs also mentions a 2007 study from The New England Journal of Medicine in which scientists concluded that gaining and losing weight can be socially contagious⁴. A person was more than 57 percent more likely to be obese⁵ if he or she has a pal⁶ that became obese. The same researchers of the study also say that happiness can spread between friends. This may mean that your friends being stressed out can affect your own levels of stress.

朋友：经常接触的人对我们的身心及情绪健康大有影响。雅各布斯还列举了2007年《新英格兰医学杂志》上刊登的一项研究：科学家发现，变瘦或发胖也有“社交传染性”。如果一个人有肥胖的朋友，那这个人也极有可能发胖。相关研究人员还表示，快乐也能在朋友之间传染。同理，如果朋友压力山大，你难免也会感到紧张不安。

Venting⁷:You may think that dumping your problems on a friend repeatedly will make you feel better, but a study by the University of Kent in England found that people with perfectionist tendencies feel worse after venting. And it doesn't just apply to perfectionists, says social psychologist Brad J. Bushman. Venting isn't an effective strategy to deal with setbacks; acceptance, humor, and positive thinking are a better ways of coping.

发泄：或许你觉得不断向朋友发泄情绪无可厚非，但根据英格兰肯特大学的研究显示，具有完美主义倾向的人往往发泄后会感到更加沮丧。社会心理学家布拉德-布什曼认为，不单是完美主义者，其他人也或多或少有这种感觉。发泄并不利于处理挫折，相反，接受、幽默和积极心态更有帮助。

Mom and dad:Your ability to deal with stress can be inherited from mom and dad. A study on about 600 twins, found that being raised in the same environment had less impact on stress management than shared genes⁸. This means that changing the environment or situation may not alleviate⁹ your stress, but it may be more effective because acknowledging and working with yourpredispositioncan help.

父母：抗压能力也受父母遗传。某项研究调查了600对双胞胎，发现相同基因对抗压能力的影响远远超过相同环境。也就是说，改变环境不一定能缓解压力。认识到这一点或许反倒更能应付压力。

Open-plan offices:It's not exactly news that your job can raise your stress levels, but the setup of your office is also a contributing factor. Many studies have shown that open-plan offices can lead to more stress among employees. Perhaps it's related to the fact that noise triggers the fight-or-flight response.

开放式办公室：众所周知，工作是压力的一大来源。其实，办公室的布局也会引发压力。已经有许多研究表明，开放式办公室更容易造成员工之间的压力，其中包括可能诱发“战逃反应”的噪音因素。

Surfing the web and texting before bed:Using certain forms of technology right before bed can stress you out. One study showed that people who texted and surfed within two hours of going to bed had greater stress levels than those who didn't, says LiveScience. However, not all forms of technology engagement increases stress. Watching TV and responding to emails apparently¹⁰ don't have an adverse¹¹ effect.

睡前上网或发短信：睡觉前玩电子产品会增加压力。《生活科学》报道说，研究显示，睡前2小时上网或发短信的人压力相对较大。当然，并不是所有电子产品都会引起压力。比如，看电视或回邮件就不会造成恶性影响。

Booze:Alcohol and stress are found to feed off each other. Drinking when you're stressed out can prolong and increase the tension you feel from the stressor.

喝酒：酒精与压力形影不离。正所谓“借酒消愁愁更愁”，喝酒最终只会使人更加紧张激动。
