Space travel is undoubtedly exciting, but it is also associated with negative effects on the human body. It is important to understand what strange things happen to the human body outside of Earth.

1. deadly space. The pressure in space is so low that the boiling point of liquids inside the body drops and gas bubbles begin to form. A person can only be conscious for 9-11 seconds, after which convulsions and paralysis will begin.
2. Nails, sorry. While in spacesuits, astronauts can sometimes experience hand injuries, including nails separating from the nail beds. Spacesuit gloves restrict movement and can cause pain and muscle fatigue.
3. Eye delusion. Astronauts sometimes report mysterious flashes of bright light in their eyes. These flashes may be caused by cosmic rays passing through the eye, and the mechanism is not fully understood.
4. legs like a child. In space, the soles of the feet soften like a newborn baby’s.
5. swollen face. The Earth’s gravity causes fluids to disperse beneath the heart. In space, fluids are distributed evenly throughout the body, causing astronauts’ faces to swell.
6. Problems with bones and muscles. Prolonged weightlessness can cause loss of muscle mass and bone tissue. Astronauts exercise to prevent these negative effects.

It is important to remember that the International Space Station and spacecraft provide conditions that guarantee the safety and health of astronauts, including artificial stress and training to maintain physical fitness. Source
