Safety from Heat Stroke

Moving out in hot Sun ? Don't forget to drink a glass or two of cold water. The network of blood vessels in our body acts just like a radiator works in a car to keep the engine cool. The radiator needs water or coolant which is kept circulating around the engine for taking away the heat. Similarly enough cold water entering the circulation takes the core heat of the body to a surface and allows enough evaporation and sweating for losing heat. In this way, the external heat is prevented from entering the body and causing heat stroke.
