Checking bed angle in bedrest study
Get some rest Why are 12 volunteers about to spend 21 days in bed, lying with their heads tilted below the horizontal? Their experience will help to understand and address changes in astronauts' bodies in space as well as in bedridden people on Earth. Far from being a period of rest and relaxation, the volunteers in this bedrest study will undergo regular and intensive daily activities, including tests and examinations. They will not be allowed to get up, not even once, for a breath of fresh air, a change of scenery, a shower or to use the toilet. The volunteers in this study are expected to repeat their 21-day ordeal twice in the space of one year. As we age, our bodies lose bone density and muscle strength. Astronauts in space suffer similar changes but at a much faster rate than on Earth. Finding ways to combat this process is important to space agencies, hospital patients and everyone who plans on growing old.
