Is it true that the Earth is a “cage” for our species?

(ORDO NEWS) — Space travel will not be able to last long, as the microgravity environment has too much influence on human physiology, leading to serious clinical diseases.

Microgravity causes a number of serious diseases. In particular, the integrity of the strong cellular barrier that lines our intestines is disrupted.

This barrier prevents bacteria, fungi and viruses from entering the human body from the intestines. Leaky gut syndrome (leaky gut or irritable bowel) can significantly increase your risk of infection and inflammation, celiac disease (digestion), type 1 diabetes, and liver disease.

Microgravity also weakens the human immune system and promotes the growth of intestinal disease-causing bacteria such as salmonella.

That is, the microgravity environment makes epithelial cells less resistant to an agent that weakens the barrier properties of these cells, and the defect persists up to 14 days after returning to Earth.

The barrier function of the intestinal epithelium is critical to maintaining a healthy gut. Permeability can lead to the leakage of unwanted substances and bacteria into the body.

But it’s not a definitive “no”. Knowing the dangers will help you better prepare for long-term space travel and colonization, during which exposure to a foodborne pathogen can lead to more serious pathologies than on Earth.
