Why Your Heart Races When You’re Nervous | RapidSmartFacts

Ever felt your heart pounding like a drum when you're nervous or anxious?

Let's uncover why! That familiar thumping is more than just a feeling; it's a complex

biological response within your body. It all begins deep within your brain,

specifically in a small almond-shaped area called the amygdala. The amygdala acts as your body's

primary alarm system, detecting potential threats and dangers. Whether it’s a real physical threat

or a perceived social one, the amygdala quickly reacts. Once triggered,

the amygdala sends a signal to the hypothalamus, the brain’s command center.

The hypothalamus then activates your autonomic nervous system, which controls involuntary bodily functions.
