Why you get an itch

You get an itch because of the stimulation of pruriceptors, which are itch-sensing nerve endings, in your skin. These pruriceptors can be activated by various stimuli like mechanical, thermal, or chemical factors. When these nerve endings are stimulated, they send signals to your brain, which generates the sensation of itchiness. Scratching or rubbing the itchy area may offer temporary relief, but it can also cause further irritation or even infection. It's important to identify and treat the underlying cause of the itch to achieve long-term relief.
