Why is the application of heat (hot water immersion) specifically noted as not recommended for Chironex fleckeri envenomation in high-risk areas?

The effort might detract from crucial symptom control and resuscitation

While heat therapy, involving immersion in water between 110–113°F (around 45°C), is cited by some authoritative sources as helpful for pain management and venom breakdown for many stings, its application for severe Australian box jellyfish envenomation requires careful triage. In high-risk geographical areas where the primary threat is immediate cardiovascular collapse from C. fleckeri venom, applying heat therapy is not recommended as a standard part of initial treatment. This is because the time and effort required to correctly prepare and apply prolonged heat therapy could potentially divert focus and resources away from more vital actions, such as stabilizing the patient's failing cardiovascular system or initiating resuscitation efforts.
