Noise is bad for you

What happens to us when things get too loud

The world is becoming ever louder. However, our ears have not evolved to deal with this constant strain. And when we feel overwhelmed by noise, this leads to stress. From 90 dB, the hormones adrenaline and noradrenaline are released, with cortisol also released at 120 dB. The arteries constrict, heart rate and blood pressure rise, and the muscles and the subconscious nervous system are affected. Beyond a certain decibel level and exposure time, hearing is also permanently damaged. When the delicate sensory hairs in the ear die, this is irreversible. Once hearing is damaged, it cannot be undone. It is therefore very important to look after your hearing.
