What happens in the brain when we feel fear?
In Parshas Shoftim, the Torah says that a soldier who is afraid should go home. Fear begins deep in the brain, in a part called the amygdala. This small, almond-shaped structure scans everything you see and hear for danger. If it senses a threat, it sends out an instant alert, before your brain finishes thinking it through, and triggers a fight-or-flight response. The heart beats faster, breathing speeds up, and muscles tense. The body gets ready to run, hide, or fight. At the same time, parts of your brain that handle logical thinking slow down—too much fear can cloud judgment. Understanding fear helps us recognize how Hashem designed our brains to help us survive, and know when to step back and when to push through.
