壓力源

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.

將自己暴露在噪音可以把壓力穿在你身上,因為它激活你的戰或逃反應,引發高腎上腺素和血壓,作者A.J.雅各布斯在他的書中倒斃健康說:一個人的卑微的追求完美的身體。

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.

雅各布斯引用的一項研究,孩子在公立學校安靜的環境下學習與那些在課堂上每五分鐘聽見火車的孩子相比。在安靜的環境下是提前一年讀六年級。

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

另一項研究表明,那些在嘈雜的環境工作的人的心臟病發病率是那些在安靜的環境中工作的人兩到三倍的。

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.

如果我們整天聽到噪音,我們的頭腦和身體將激活“戰或逃反映”,這意味著我們不得到急需停機時間。
