In the micro-gravity of space, the human body loses muscle and bone density.

Not only that but eyes change and fluids shift to the brain, among other issues.

The European Space Agency (ESA) is deep diving into dry-immersion baths as a way to recreate aspects of living in microgravity, part of their human spaceflight research.

In suspension

Similar to bath tubs, large containers hold study participants in suspension for many days.

ESA explains that the studies benefit from placing less pressure on the body as volunteers are supported and suspended evenly in the tub. In that way a condition is created that mimics the floating astronauts experience on the International Space Station.

“Results from this type of research,” ESA states, “does not only benefit astronauts but has implications for people on Earth who are bedridden for long periods of time.”
