Anxiety makes reading facial expressions harder, study suggests

Anxiety can do many things to the body, including increasing blood pressure and heart rate. But a new study suggests that it does not stop there. Researchers from the University of Bristol suggest a heightened state of anxiety affects the ability to read facial expressions, with some people unable to distinguish between happy and angry.
The study, State anxiety and emotional face recognition in healthy volunteers, was published in the journal of Royal Society Open Science.
They found that those suffering from a heightened nervous disorder saw angry facial expressions more often than not.
