Checking fluids

Medical staff at MEDES in Toulouse, France, checking on a bedrest volunteer. During this session the volunteers spend 21 days non-stop in bed and are subjected to all manner of tests, experiments and monitoring to understand how the body reacts to immobility.

Bedrest studies can answer questions on how our bodies adapt to living in space and on how our bodies adapt to growing old. Many of the findings from bedrest studies apply directly to people on Earth.
