How Lying In Bed For 60 Days Helps Astronauts
Ep 2 · Jun 24, 2025 · 27 min
In space, microgravity changes the body. Body fluids shift from the legs toward the head, the back of our eyes flatten, we lose muscle strength, our bones lose some of their density, and even the amount of blood pumped by the heart with each beat drops. To learn more about how microgravity affects the human body and develop new ways to help astronauts stay healthy, scientists are asking dozens of volunteers to spend 60 days in bed with their heads tilted down at a specific angle. This research a…
