Recent research published in Nature journals shows that space tourists undergo physiological changes similar to astronauts during space travel.

Data from the Inspiration4 mission by SpaceX revealed shifts in cells and changes to the immune system.

Approximately 95% of health markers return to normal within three months of returning to Earth.

Studies on four space tourists highlighted the impact of spaceflight on the skin, kidneys, and immune system.

Overall, short-term spaceflight did not pose significant health risks.

Female astronauts may tolerate space travel stress better due to their bodies' adaptability.

Researchers are optimistic about the feasibility of safe Mars missions despite concerns about radiation exposure.

The findings provide valuable insights for both astronauts and the emerging space tourism industry.

Emphasis is placed on the need to counteract the negative effects of space travel.
