In fact, itching is a defense mechanism. From the evolutionary point of view, in ancient times, in order to resist the stimulation of the external environment, the human body must maintain a sensitive state, even if it was slightly itchy.

Some people think that people with very good itching reflex become the best survivors in nature, while those who do not respond to itching are gradually eliminated. Therefore, in the long run, it has become a reaction of people.

Modern research has found that itch receptors are widely distributed on human skin, and everyone's nerve endings respond differently to external stimuli, so some people are particularly afraid of itching.

In addition, nerve endings in armpits, soles and other places are more abundant than other parts, so they are more sensitive to external stimuli, so they will feel itchy when scratching the soles of their feet and creaking their nests.
