Itching is most often called the released histamine, which affects the nerve endings. The reasons for the release of histamine are usually allergic. As you know, scratching relieves itching. That is why this happens: blood rushes to the site of scratching of the itchy area - this accelerates the local nonspecific immune response to the released histamine. So, when an itchy area of ​​the skin gets under hot water, the vessels expand and blood rushes to it, which also accelerates the immune response. Mechanical and thermal effects equally relieve itching, only scratching is more effective, because it allows you to irritate with the desired intensity and only the desired area, without affecting others.
