Researchers from UT Southwestern Medical Centre have developed a vacuum-equipped sleeping bag intended for astronauts. The sleeping bag pulls down body fluids that naturally flow to the head and squash the eyeballs, preventing associated vision problems.
Scientists hope the hi-tech sleeping bag will stop eyeballs being squashed by zero-gravity in space.
The sack built at the University of Texas Southwestern Medical Center works by using vacuum tech to relieve the fluid pressure on the brain and the optical nerve.
