"Your nervous system’s job is to protect you from harm." Information overload, overstimulation and uncertainty can keep the brain on high alert, activating the autonomic nervous system, the neurologist said.

The neurologist outlined the following five strategies for recognizing these patterns, calming the nervous system and developing healthier responses to stress.

When seeing patients, Resnick said his first step is to listen to them, to ensure that he understands what they’re feeling.
