What is the ideal temperature for hot water immersion for a stingray sting?

Around $110^ ext{F}$ or $43^ ext{C}$

The recommended protocol for treating a stingray sting via immersion requires the water temperature to be significantly elevated to effectively denature the venom proteins, yet kept low enough to prevent thermal injury to the patient. The specific target temperature cited is approximately $110^ ext{F}$ or $43^ ext{C}$. This temperature range is hot enough to destabilize the venom's protein structure quickly, facilitating pain relief, but it must be monitored carefully as it is the highest temperature the individual can safely tolerate without actually causing a burn. If the water is too cool, the venom remains active; if it is too hot, secondary burns introduce new complications, underscoring the importance of hitting this specific thermal benchmark.
