It appears that the sounds we hear throughout the day impact our mood and mental health. In a new study published in the journal Scientific Reports, researchers at the Max Planck Institute for Human Development in Germany studied the effects of traffic noise and birdsong on close to 300 participants. They found that listening to birdsong significantly reduced anxiety and paranoia. It did not have a noticeable effect on depression. On the other hand, traffic noise worsened the participants’ depressive states. Going outside, or even listening to birdsong audio clips, might be a way to improve your mental health and well-being.
