Space travel weakens the immune system of astronauts.. Know the details of the discovery


A new study, published in Nature Scientific Reports, about that cells (Tregs) in the human body suffers from abnormal activation during space travel, and with its activation, this affects the immune systems negatively, and astronauts are exposed to disease after returning to Earth.

According to the British newspaper, “Daily Mail”, the researchers simulated an immune response, and put a chemical that was used to mimic pathogens in blood samples, and eventually found that Tregs I started to activate.

Significantly, we found that microgravity simulation enhanced signaling responses STAT5 for immunosuppressive signals.

The researchers added, “Our results indicate that microgravity exerts a dual effect on the human immune system, at the same time dampening cellular responses while enhancing cellular function. Tregs“.

A number of Apollo astronauts suffered from colds or other infections, with many experiencing reactivation of dormant viruses, such as chickenpox.

The early Apollo astronauts also suffered from other disabilities, such as inner ear disorders, an irregular heartbeat, low blood pressure, dehydration, and a loss of calcium in their bones.

Also, after Apollo 11 astronauts, Neil Armstrong, Michael Collins, and Buzz Aldrin returned to Earth, they were quarantined for three weeks for fear of pathogens returning from the moon.

Recounting his time during quarantine, Aldrin tweeted that he spent his time writing task reports, making debriefs and exercising.

The study findings come right after emerging space tourism and concerns about the health of space travelers are making their way into society, and the space tourism industry is expected to be worth $23 billion by 2030, it is reported. CNBC From before.
