Reducing anxiety and stress with pupil feedback

The brain’s state of arousal is the key to many stress-​ and anxiety-​related disorders. Researchers at ETH Zurich have now found a way to influence it with a new biofeedback method.


In brief

  • Researchers at ETH Zurich demonstrate that the arousal centres in the brainstem can be influenced when we receive feedback about pupil size.
  • This biofeedback helps us learn effective relaxation or activation techniques.
  • In the future, this means stress-​ and anxiety-​related disorders could be treated in a playful way using a VR headset.
