压力源

Noise

噪音

Exposing yourself to loud noises can wear on you because it activates your flight-or-flight response, triggering higher a drenaline and blood pressure, says author A.J. Jacobs in his book Drop Dead Healthy: One Man's Humble Quest For Bodily Perfection.

将自己暴露在噪音可以把压力穿在你身上,因为它激活你的战或逃反应,引发高肾上腺素和血压,作者A.J.雅各布斯在他的书中倒毙健康说:一个人的卑微的追求完美的身体。

Jacobs cites a study that compared kids at a public school who studied in quiet settings vs. those who were in classrooms who hearda train go by every five minutes. Those in the quiet setting were one year ahead in reading by the sixth grade.

雅各布斯引用的一项研究,孩子在公立学校安静的环境下学习与那些在课堂上每五分钟听见火车的孩子相比。在安静的环境下是提前一年读六年级。

Another study showed that people who worked at noisyjobs had two to three times the heart problems as those who worked in quiet environments.

另一项研究表明,那些在嘈杂的环境工作的人的心脏病发病率是那些在安静的环境中工作的人两到三倍的。

If we're hearing loud noises all day long, our mindsand bodies will keep activating the fight-or-flight response, which means wedon't get the much-needed downtime.

如果我们整天听到噪音,我们的头脑和身体将激活“战或逃反映”,这意味着我们不得到急需停机时间。
