ELI5, why do minty things feel cold?
gpt
It happens that the nerves in our mouth that are sensitive to cold are also sensitive to menthol, which is the chemical that makes mint taste minty. When you eat mint, the nerves that sense coldness are activated and you experience cold.

A similar thing happens when you eat hot chilis. In that case, the chemical is called capsaicin. The nerves in your mouth that sense heat are triggered by capsacin and when you eat it, it feels like your mouth is on fire.
