👉 Fluids, including water and other bodily fluids, have several inherent limitations. Firstly, they are subject to evaporation and excretion, leading to a constant loss of volume and concentration changes over time. Secondly, their properties such as viscosity and density can vary significantly with temperature, affecting their behavior in different environments. Thirdly, fluids cannot store energy; they only convert between different forms (e.g., from liquid to gas), limiting their capacity for sustained energy provision. Lastly, fluids are susceptible to contamination and degradation, which can alter their composition and impair their functions. These limitations highlight why maintaining fluid balance is crucial for optimal health and bodily function.
