Why Does Spicy Taste 'Hot' and Minty Taste 'Cool'?

The video explains why mint tastes cool and chili tastes hot by exploring how certain chemicals activate the same sensors in our bodies that detect temperature. Ion channels in nerve cells are triggered by different stimuli, and some chemicals can mimic these stimuli. Menthol in mint binds to the TRPM8 ion channel, tricking the brain into sensing cold, while capsaicin in chili binds to the VR1 ion channel, making the brain perceive heat. Thus, the sensations of hot and cool flavors are not metaphorical but are based on actual sensory responses.
