When astronauts return to Earth, they often experience orthostatic intolerance—a condition where their bodies struggle to adjust to Earth’s gravity in an upright position. In space, their bodies adapt to microgravity, which weakens leg muscles and causes cardiovascular changes. Back on Earth, standing up can lead to a sudden drop in blood pressure, resulting in fainting or lightheadedness. It takes time for their bodies to readjust and function normally in Earth’s gravity. This phenomenon underscores the challenges of shifting between different gravitational environments.
