A remedy for athletes foot, when the skin is breaking down and cracking open is salty water 115 degrees Fahrenheit. My feet turn RED, and it kills the fungus.
An experiment concerning your butt: Use a digital chef's meat thermometer.
Make a POT or bucket of such a foot bath, OK? Take a sip, your mouth knows about hot drinks, giving you a good reference along with the digital.
Sit in a chair and put you feet in the 115F till they tell you, "Ee-enough!"
Now sit in it. Predictably, your butt will not get nearly as agitated by the hot water as your feet do and will let you sit in it with no alarming problem at all.
YOU HAVE TO TAKE CARE AND PROTECT YOUR ASS,,, hole buddy. Your anus and colon are not able to give you hot signals like your feet or mouth.
To all my friends, please do not infuse with enema waters above 105 degrees Fahrenheit. 😉
If you have ever made any kind of cultured brews, we never allow it to get up to or even near 110 F
That is why a short dip into 115 F is therapeutic on infected feet. But on the other hand do not force anyone to keep their feet in hot water either, nor their butt. It can be destructive.
I have used hot saline wash rag to hold against an infected eye lid. But understand, this is lots different than flooding your innards with hot water. 😕
