How come scolding hot showers feel so good on a Poision Ivy rash?

In: Biology

The itchiness is caused by a protein, proteines denture under heat, which is why hot water provides a great relief from itching sores. Works for mosquito bites as well.

It’s because the same nerves that convey the itchy feeling also convey the feeling of heat. Your nerves can only handle so many impulses at once before they temporarily shut down to rest. The super hot water overwhelms the itchy nerves and causes them to shut off for a while.
