What Causes Anxiety?

Based on a Harvard Medical School article, anxiety is a reaction to stress that has both psychological and physical features.

As neurotransmitters carry the impulse to the sympathetic nervous system, heart and breathing rates increase, muscles tense, and blood flow is diverted from the abdominal organs to the brain. In the short term, anxiety prepares us to confront a crisis by putting the body on alert.

And when it persists, anxiety can take a toll on our mental and physical health.
