NASA is conducting a bed-rest experiment to allow scientists to study some of the effects of microgravity on the human body.
It will take place in the Human Test Subject Facility of Johnson Space Center and the participant will be paid $17,000 to stay in bed for 90 straight days.
According to Human Test Subject Facility website:
Participants will spend 90 days lying in bed, (except for limited times for specific tests) with their body slightly tilted downward (head down, feet up). Every day, they will be awake for 16 hours and lights out (asleep) for 8 hours.
The purpose of this test is to study the effects of gravity on human body because astronauts who’ve spent lengthy stays in space have suffered serious repercussions. Our bodies have evolved mechanisms to deal with a certain amount of gravitational force–namely, the amount present on Earth; reduce g and blood pools in the feet, muscles atrophy and bones lose their density. It can take astronauts months to readjust to the Earth’s gravitational force.
