Hydration refers to the process of consuming fluids to maintain a balance of water and electrolytes in the body. Hydration is essential for the optimal functioning of the body, as water is necessary for a variety of bodily functions such as digestion, regulating body temperature, and transporting nutrients. Hydration products can include water bottles, hydration packs, electrolyte supplements, and other products designed to promote proper hydration during physical activity or in extreme environments. Proper hydration is especially important during exercise, outdoor activities, and in hot and humid conditions to prevent dehydration and heat-related illnesses.
