    Why is it that after you eat something minty, your mouth feels cold and after you eat something spicy, your mouth feels hot?

    Question #78767. Asked by kisstherainbow. (Apr 12 07 7:42 PM)


    Rizeeve

    		The cold and hot sensations are due to electrical patterns in our brains from the sensation of eating particular things. Menthol in mints interacts with nerve cells called TRP-M8, signalling cool temperatures to our brain. Similarly, molecules in spicy foods will affect nerve cells called TRP-V1, signalling hot temperatures to our brain.

    Why is it that when you are suntanning all day your body feels cold in normal room temperatures in the evening?

    I know the temperature where I am isn't anything like it is where Qp lives, but it still feels cold here. In Celsius and Fahrenheit, you can have negative (minus) temperatures. Can you have them in the Kelvin scale? (Beware - Baloo at work...)

    Does the suffix '-mouth' in a place name refer to the mouth of a river, as in Plymouth, Dartmouth, et al?
