Why do some mints make water 'taste' colder?
gpt
You have cells with enzymes that act as receptors to signal warmth and cold. The molecule menthol, which gives mint its taste, activates your cold receptors and gives a 'cold' sensation. Capsaicin, the molecule that gives chili its 'hotness' works in a similar way, activating heat receptors.
