Body: You have separate receptors for warm and cold — not one…

Question

Did you know? You have separate receptors for warm and cold — not one temperature sense. That's why 30°C water feels FREEZING in your ear but lukewarm on your hand: ears have many more cold receptors. The "menthol" in toothpaste isn't actual cooling — it just chemically activates your cold receptors.

You have separate receptors for warm and cold — not one temperature sense. That's why 30°C water feels FREEZING in your ear but lukewarm on your hand: ears have many more cold receptors. The "menthol" in toothpaste isn't actual cooling — it just chemically activates your cold receptors.

Je hebt aparte receptoren voor warm en koud — niet één temperatuur-zin. Daarom voelt 30°C-water IJSKOUD aan in je oor maar lauw aan op je hand: oren hebben veel meer koude-receptoren. De "menthol" in tandpasta is geen koeling — het activeert alleen je koude-receptoren chemisch.
