What immediate action should you take if you suspect someone is experiencing heat stroke?

If you suspect someone is experiencing heat stroke, the most immediate and crucial action is to move them to a cooler environment. This is essential because heat stroke is a serious condition characterized by an elevated body temperature that can lead to organ failure and potentially be life-threatening. Quickly reducing the ambient temperature is vital to prevent further physiological damage and help stabilize the individual.

While other measures, such as encouraging fluid intake or using wet towels, can be beneficial in mitigating heat-related illness, they are not as immediately effective as relocating the person to a cooler area. It's important to prioritize actions that directly address the dangerous hyperthermia associated with heat stroke. By moving the individual to a cooler environment, you not only help lower their body temperature more rapidly but also provide them with a more conducive setting for further medical care.

Performing abdominal compressions is not relevant in this scenario; such an action does not address the symptoms or the dangerous rise in body temperature associated with heat stroke and can divert attention from necessary cooling measures.
