Why are the soles of your feet itchy? But some people are not afraid? How to avoid it?

people do feel itchy. Usually, our armpits, groin, soles and other places are most sensitive to itching. The reason is that these places are "non-exposed areas", and there are few chances of being scratched and stimulated at ordinary times. In addition, the skin receptors in these parts are rich and combined, so the feeling of itching is much more acute. But some are most ticklish in nose hair, eyelashes and lips, followed by armpits and soles.

people are different. I think these are all congenital. Since they are not diseases, I think it is useful to avoid them on purpose.
