ELI5:why is cold water so much colder after eating a mint?
gpt
**Menthol is the chemical in peppermint that stimulates the cold-sensitive nerve receptors in the tongue and skin.  It does not cause a drop in temperature, just the sensation of that.  Other chemicals that trigger temperature sensations are capsaicin (chili peppers) and zingerone (ginger) which both cause a sensation of heat (but don't change the temperature).**
