what exactly causes non specific itchiness of the skin, not due to health issues, and why is it often felt in different areas at the same time?

Question

In: Biology

Answer 1

You are shedding dead skin cells all the time. Exfoliating the skin by rubbing it scratching feels good, so sometimes your skin just “wants” to be scratched.

If it happens a lot, you could have dry skin or allergies.
