How Lying In Bed For 60 Days Helps Astronauts
Jun 24, 2025
Join Dina Feinmarin, a writer for NASA's Human Research Program, Andreas Joshi, a volunteer in a groundbreaking bedrest study, and Tim McCauley, a NASA scientist focused on health impacts in space. They discuss how lying in bed for 60 days simulates the effects of microgravity on the human body. The group explores muscle loss, balance issues, and innovative gaming exercises to keep astronauts fit. Dive into the rigorous selection process and learn why this research is vital for future missions to Mars and the Moon!

Episode notes
Adapting to Head-Down Tilt Pain
- Andreas Joshi experienced intense back pain the first night in head-down tilt bed rest.
- By day five, his body adapted, and the position became his new normal.
Combating Muscle Loss and Balance
- Astronauts lose balance and muscle strength despite in-flight exercise.
- NASA tests electrical muscle stimulation and balance training to improve post-flight recovery.
Use Gaming for Balance Training
- Try balance training with a tilt board air sled to simulate instability while lying down.
- Use the foot-controlled video game to engage and challenge balance muscles during bed rest.
