Scientists have developed a hi-tech sleeping bag that could prevent the vision problems that some astronauts experience while living in space.
In zero-gravity, fluids float into the head and squash the eyeball over time.
It's regarded as one of the riskiest medical problems affecting astronauts, with some experts concerned it could compromise missions to Mars.
The sleeping bag sucks fluid out of the head and towards the feet, countering the pressure build-up.
Its development was led by Dr Benjamin Levine, professor of internal medicine at University of Texas (UT) Southwestern Medical Center in Dallas, who is working on having the device deployed on the International Space Station (ISS).

What will they think of next. A sleeping bag that sucks the fluid from your eyeballs and sends it towards your feet.

In 0 gravity, body fluids react to pressure, I don't think it would matter if you were upside down or standing etc.
