Loud Noise is Harmful

Too much information or communication, especially when it’s loud can harm you. The health effects of sound may, literally, echo through our bodies. A study in the Journal of Occupational Health took nighttime readings on workers who were exposed to loud sounds during the day.

The workers' sleep quality was poor, their nighttime heart rates never dropped as low as those of people not exposed to noise, and their cortisol levels were still elevated the following morning.
