Which measure could help prevent heat cramps, heat exhaustion, and heat stroke?

Drinking plenty of fluids is crucial in preventing heat cramps, heat exhaustion, and heat stroke. When the body is exposed to high temperatures, it loses water and essential electrolytes through sweating. Maintaining proper hydration helps regulate body temperature, supports cardiovascular function, and ensures that sweat can evaporate efficiently, which is the body's natural cooling mechanism. By consuming adequate fluids, individuals can replenish what is lost and mitigate the risk of heat-related illnesses.

The other choices do not provide the necessary support for preventing these heat-related conditions. Decreasing salt intake may actually hinder the body's ability to retain fluids and electrolytes, which can exacerbate dehydration. Taking fewer work breaks can lead to prolonged exposure to heat, increasing the risk of overheating. Wearing heavier clothing fosters heat retention rather than allowing the body to cool down, which can contribute to heat-related complications.
