Heat-related illnesses can be prevented by keeping hydrated and using portable coolers while working outdoors or in hot environments. Hydration and fluid replenishment can be achieved by drinking bottled water, sports drinks, and thirst quenchers. During transportation, coolers keep food and beverages chilled and contained. A sports drink and thirst quenchers can provide hydration after physical exertion. Heat-related illnesses can be prevented if these products are used in high-heat environments.
