Fair question.
If spicy food feels like it’s burning your mouth, why isn’t your mouth actually on fire?
Because capsaicin — the compound that gives chili peppers their heat — activates TRPV1, a receptor that also responds to heat and helps trigger that burning sensation.
“Then why does it hurt?”
Because those sensory nerves are still sending your brain a very convincing HOT / BURNING signal, even though there’s no actual flame involved.
So technically, no fire.
Gary brought the extinguisher anyway.
What weird body fact should Gary investigate next? 🌶️
