Space travel has been found to have detrimental effects on the human body, according to a recent study published in Nature Communications. The research, which focused on the immune system, revealed that spaceflight can cause mutations in DNA, wasted muscles, and even ‘blood destruction’.

The study, based on data collected from the SpaceX Inspiration4 mission in 2021, observed that the immune system undergoes significant changes during space travel. In particular, the immune system becomes dysregulated, leading to inflammatory responses and disruptions at the cellular level.

One of the key findings of the study was the impact of spaceflight on muscles. Researchers identified the production of various cytokines, which are substances secreted by the immune system and play crucial roles in immune response and muscle regulation. Some of these cytokines, known as exerkines, are proteins produced by muscles during exercise.

The study also noted that muscle tissue showed significant increases in certain myokines, proteins produced by skeletal muscle cells. These changes were attributed to a physiological response to microgravity rather than a typical immune response.

Interestingly, non-muscle tissues did not exhibit alterations in key proteins associated with inflammation, indicating that the effects of space travel on the body are complex and multifaceted.

While the study highlighted the negative impact of space travel on the human body, it also suggested that women may have a biological advantage when it comes to withstanding these effects. Further research is needed to fully understand the long-term implications of space travel on human health.

Overall, the study sheds light on the horror effects of space on humans and underscores the importance of further investigating the physiological changes that occur during spaceflight.
