Curling your tongue may seem like a party trick, but science shows it taps into one of the body’s most powerful relaxation systems. When you curl the tongue, you activate cranial nerves that are deeply connected to the vagus nerve. The vagus is the main highway of the parasympathetic nervous system, responsible for lowering heart rate, calming the stress response, improving digestion, and even balancing inflammation.

Modern studies show that vagus nerve stimulation reduces anxiety, improves mood, and promotes resilience against stress. Research has also demonstrated that simple tongue and oral movements influence cranial nerve pathways that connect directly to the autonomic nervous system. This is why curling the tongue can instantly shift your body from “fight-or-flight” into “rest-and-digest.”

Try it right now: curl your tongue, take a few slow breaths, and notice the difference in how your body feels. Subtle signals — like increased saliva, a sense of warmth, or calmness — are all signs that your parasympathetic system is kicking in.
