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.

 

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.

 

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

 

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.
