Are allergies impacting your nervous system or is your nervous system causing your allergies?
I am asked this after people begin to understand how their body tells a story.
The answer is actually both. It is a continuous loop.
Under normal circumstances, your autonomic nervous system is the driver. It actively swells the tissue in your nose to close one side and open the other. It does this on purpose to force your brain to switch gears between resting/parasympathetic nervous system and focusing/sympathetic nervous system.
But when you have a physical blockage in your nose, like allergies, stuffiness, sinus inflammation or a deviation, that feedback loop breaks.
Your brain relies on the sensation of airflow to confirm that your nervous system has switched. If you physically cannot breathe through the side your brain is trying to activate, the signal never is transmitted.
If your left side is blocked, you lose the feedback loop to your parasympathetic system. Your body can’t get the clear signal to rest and digest, so you stay stuck in a wired, anxious state.
If your right side is blocked, you lose the connection to your sympathetic system. You struggle to trigger the alert response, leaving you feeling foggy or unmotivated.
The nervous system tries to drive the car, but without that airflow, the wheels aren't turning.
This is the classic chicken or egg story. Are you allergies or stuffiness cutting off your nervous system OR is your nervous system causing your allergies?
Try this test, plug each side of your nose one by one and breathe in. Which side feels like less air flow?
