The anti histamine theory makes the bathes make sense. I knew from boy scouts to treat itch with hot water. Check this out.
"A hot bath or shower often produces relief in that heat releases histamine, the substance in the skin that causes intense itching. Therefore, a hot shower will cause intense itching as the histamine is being released. The heat should be gradually increased to the maximum tolerable and continued until the itching subsides. This process will deplete the cells of histamine, and the patient will obtain up to 8 hours of relief from itching.". https://www.healthcentral.com/encyclopedia/p/poison-ivy-and-poison-oak
Is the bath releasing histmines? And thus the comfort? can this be treated like an allergy regardless of causation?
