Sponge off the victim with cold water. Seek medical attention immediately. Heat stroke causes nausea, delirium and possibly vomiting, and your organs shut down. Drinking could lead to more nausea and vomiting. Children can withstand the heat better than adults.
Children lose water at the same rate as adults.
But since they have less body mass, the effects are more severe. When it's hot outside, no heat transfer can occur, and your body overheats like a high-revving car engine. Just 4 to 8 ounces of water can replenish lost fluids. Otherwise, you can get heat cramps or painful muscle spasms. Water is the best thirst quencher.
