History Photographed on Instagram: "This is the phenomenon of astronauts temporarily having difficulty readjusting to Earth's gravity after spending time in space.⁠ ⁠ This condition, which is called orthostatic intolerance, is a condition where the 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 press
