I have been a subscriber to How It Works for over two years and I have loved every issue. I was wondering, why does my mint shower gel make me cold? Thanks,

Thanks for the question Henry! Mint contains menthol, which can really mess around with how you perceive temperature. Your nerves are telling your brain it is cold, when it’s not really because it triggers a protein called TRPM8 in your skin. This causes the cold receptors to become particularly sensitive and over fire. Nobody is sure why this happens, but it’s likely that the menthol ‘key’ just fits perfectly with the cellular ‘lock’. Thanks for the question Henry.
