When Sweat Stops WorkingBy midmorning in Santo Domingo, the air no longer feels passive. For the athletes arriving from 37 countries for the twenty-fifth Central American and Caribbean Games, that heaviness has become an opponent no coach can scout. The image is almost mythic: a Caribbean competition disrupted by sand lifted from another continent. Olympic medical protocols also recommend confirming suspected heatstroke through core-temperature measurement and using ice-water immersion when seconds matter. Centro Caribe Sports is using the international Wet Bulb Globe Temperature index, or WBGT, which combines heat, humidity, and solar radiation.
