WHAT'S ALL THAT RACKET?
In the past 25 years, the number of honking cars on the road and roaring planes in the air has ballooned. And consider all the new noises that didn't exist until fairly recently, like surround-sound movie theaters, car alarms, and ring tones. Sudden loud noises trigger a fight-or-flight response: The heart pumps harder, blood pressure rises, and the body releases stress hormones including adrenaline and cortisol. It's the inability to predict the sound that brings on the response; that's why the blast from your blender doesn't stress you out the way the sudden revving of a motorcycle does, even if the blender is actually louder. Here's how to stay healthier:
- Noise-proof your health
- Close your windows
- Sleep with earplugs
- Use noise-reducing headphones
- Replace your rumbling dishwasher
- Install sound-absorbing insulation
