👉 You’ve probably heard of the vagus nerve. But what does it actually do?
It’s one of the main nerves connecting your brain to your body and plays a big role in how your system regulates itself day to day. It helps control heart rate, breathing, digestion, and how your body responds to stress.
When everything is working well, your body can recover after stress and return to its normal state. When it’s not, that recovery process doesn’t happen as easily, which is why symptoms like dizziness, chest tightness, digestive issues, or a constant sense of tension can stick around even when medical tests don’t show anything concerning.
