Hydration plays a critical role in metabolic processes, as water is essential for nutrient absorption, digestion, and waste elimination. Proper hydration facilitates the transport of oxygen and nutrients to cells while helping to regulate body temperature. Dehydration can impair metabolic function and lead to decreased exercise performance, fatigue, and muscle cramps. Consuming adequate fluids is crucial for optimal energy levels, efficient metabolism, and overall health, ensuring that the body performs at its best during physical activities.
