Does your heart race when you get an unexpected text? Do you find yourself jumping at small noises or feeling constantly on edge? Your amygdala - your brain's built-in alarm system - might be working overtime. It is trying to protect you from danger, even when there isn't any. That's its job. Not to decide when there is danger, but to be ready- in case there is some. While this ancient protective mechanism kept our ancestors alive, it can become overwhelmed by modern life's constant stream of perceived "threats" that aren't physically dangerous - from work deadlines to social media notifications.
