10 Scary Things That Happen To Your Body In Space

The video explores ten physiological effects of space on the human body, including blood boiling, bone density loss, lung risks, fluid behavior, sleep disorders, radiation exposure, body expansion, muscle shrinkage, freezing, and heart changes. Each section delves into the scientific reasons behind these effects and their potential long-term impacts on astronauts' health. The video concludes by encouraging viewers to reflect on these challenges and consider their willingness to travel to space.
