Effective management includes prompt on‑site cooling and symptomatic treatment followed by intensive care for severe cases. In keeping heat‑related illnesses low, indoor stay, hydration, and public awareness campaigns play important roles. The urge of the article, therefore, is that HS demands very serious attention from the global arena and its proactive measures should be enforced to avert this medical emergency globally.
