When we say “touch,” we usually think of one sense - that feeling of contact. Anatomically, touch is really four different senses bundled together, each handled by its own kind of receptor in your skin.
There are mechanoreceptors, which detect pressure, vibration, and stretch. They’re what tell you you’re being touched at all, and they’re the most plentiful - your fingertips have an especially dense supply, which is why your hands are so good at exploring fine textures. There are thermoreceptors for temperature - separate cells for warmth and for cold. And there are nociceptors for pain - your damage detectors.
This is why touch can feel like multiple things at once. Holding ice triggers cold thermoreceptors AND pressure mechanoreceptors AND, if it’s really cold for long enough, pain nociceptors too. Your brain combines all of them into the single experience of “holding cold ice,” but really it’s getting four kinds of signal at the same time.
