Why Does Mint Feel Cool in Your Mouth?
Menthol can activate TRPM8, a sensory channel that also responds to cooling. This can feel cool even when the food itself has not become colder.

What the illustration shows
Navy-and-gold poster titled Why Does Mint Feel Cool in Your Mouth? An open mouth with a gold sensory-ending overlay sits beside green mint leaves. A dotted connector leads to a circular membrane inset. Cyan arrows labeled Cooling and Menthol both point to a TRPM8 channel labeled conceptual, not a molecular model. A gold sensory-signal arrow leads toward a small head and brain icon labeled Cool sensation. The takeaway explains that menthol can activate TRPM8 and feel cool without the food becoming colder. The plain navy footer carries AllHumanBody.com and the full slogan.
How to interpret this poster
- The channel is not a molecular model or the only cold sensor. Response varies; no actual temperature drop, product efficacy, dose or health benefit is implied.
- AI-assisted educational illustration; not physician certification, microscopy, a diagnosis or individualized medical advice.
- Fine annotations need enlargement; the full description provides an accessible text alternative.
- Display the full uncropped illustration; do not trim titles, legends or boundary annotations.

EVIDENCE / CONTEXT
Sources and what they support
- Southern Cross University scientist-authored physiology explainer ↗
Supports oral menthol cooling through TRPM8 and separates sensory coolness from product temperature. Its broad all-receptors-open wording and proposed spreading explanation are not adopted.
- Peier et al., Cell 2002, primary channel-identification study ↗
Shows cloned TRPM8 responds to cold and menthol in experimental expression systems. This is mechanistic cell/animal evidence, not a human mint-product trial or proof that TRPM8 is the only cold sensor.
Evidence correspondence is limited to the abstract.
