    Why these volunteers are in bed for 60 days straight

    A group of volunteers is spending two months lying in bed—with their feet up and one shoulder always touching the mattress—even while eating, showering, and using the toilet. But why? This extreme bedrest study is helping scientists understand how space travel affects the human body and how to keep astronauts healthy on long missions.

    Microgravity causes muscle and bone loss, fluid shifts, and other physiological changes similar to those experienced by bedridden patients on Earth. By studying volunteers here on Earth, researchers can develop better countermeasures for astronauts and even improve treatments for medical conditions like osteoporosis.

    In this study, participants are divided into three groups: one stays in bed with no exercise, another cycles in bed to mimic astronaut workouts, and a third cycles while being spun in a centrifuge to simulate artificial gravity. Scientists hope artificial gravity could become a key tool in protecting astronauts during deep-space missions.

    Could you handle 60 days in bed for the sake of space exploration? Let us know in the comments!

    There is no point in sending human explorers on long voyages around the solar system if they arrive at their destination in poor physical shape. Long stays in zero gravity are not good for the human body.

    We already know that astronauts lose bone mass at around 1% for every month they are in space; muscles – including heart muscles – atrophy despite hours of exercise; and there are a host of other problems.

    Humans are adaptable beings. Wear glasses that turn your view of the world upside-down and within two weeks your brain will have adapted to the topsy-turvy world.

    Researchers suspect that astronauts’ brains adapt to living in weightlessness by using previously untapped links between neurons. As the astronauts learn to float around in their spacecraft, left–right and up–down become second nature as these neuronal connections are activated.

    To confirm this theory, up to 16 astronauts will be put through advanced Magnetic Resonance Imaging (MRI) scanners before and after their flights to study any changes in their brain structure. A control group on ground will undergo the same scans for further comparison.

    The research is providing scientists on Earth clues where to look in the brains of people who suffer from disorders based on previous traumatic experiences such as vertigo.
