What is the recommended temperature range for hot water immersion used for pain management after a Man-o'-War sting?

Answer

About $45^ ext{o} ext{C}$ ($113^ ext{o} ext{F}$).

Once the venom cells are deactivated and tentacles are removed, the primary focus shifts to alleviating the severe residual pain caused by the injected venom. The most effective, non-pharmaceutical treatment supported for this involves thermal therapy. The affected area must be submerged in hot water kept at a temperature that is tolerable to the skin but hot enough to break down the toxin, specifically cited as approximately $45^ ext{o} ext{C}$ or $113^ ext{o} ext{F}$. Immersion in water within this precise range, sustained for 20 to 45 minutes, is necessary to denature the protein-based components of the venom responsible for the lasting discomfort.
