Fluid Balance
Fluid balance refers to the state of equilibrium between the intake and output of fluids in the body. In the context of space and astronautical engineering, fluid balance is a critical aspect of human spaceflight as it is essential for maintaining the health and well-being of astronauts. The microgravity environment of space can cause significant changes in fluid balance, leading to a shift of fluids from the lower extremities to the upper body, resulting in facial edema, puffy eyes, and other symptoms. Astronauts must maintain proper fluid balance through a combination of hydration, exercise, and dietary measures. The study of fluid balance in space is an ongoing area of research, with the goal of developing effective countermeasures to mitigate the negative effects of microgravity on the human body.
