Liz Warren, NASA Johnson Space Center operations lead for the International Space Station Medical Project, discusses why exercise and nutrition are important to maintaining good health on Earth and even more important to astronauts on the International Space Station. She also discusses how living in space causes changes in the human body such as loss of bone density, decreased cardiovascular fitness, and muscle atrophy. Astronauts participate in experiments to measure changes in their bodies so that we can prevent those types of changes in the future.
