Why do astronauts easily die from cardiovascular disease?

Those who discovered the universe on Apollo spacecraft were found to be five times more likely to suffer from cardiovascular disease.

The scientific world is preparing to bring people to the universe to carry out their mission longer and deeper. Mars is the target of both private firms and state space agencies. And those pioneers who do such expeditions will endure their bodies with dangerous radiation conditions in the universe.

A recent study found a worrying fact about the risk of astronauts having higher cardiovascular disease after they were exposed to the radiation environment.

In the first study related to the deaths of astronauts traveling on Apollo - manned spacecraft that advanced the most far into the universe, including the mission to land on the Moon - shows near a half of them died of cardiovascular disease.

The authors of the study published in the journal Nature Nature in mid-2016 evaluated the health records of seven astronauts (out of 24) who had explored the Apollo ships and died.

The team compared those who died with astronauts who only flew in Earth's low orbit and those who had recently completed training but had not left Earth. The results show that the risk of those who fly deep into the universe is 43% higher than the other groups.

The cause is thought to be due to radiation in the universe . Energy rays in the universe and solar particles emitted from the solar storm are the cause of radiation.

hinders long-term missions in the future. The US Aerospace Agency (Nasa) calls this a "significant threat".

In 2013, NASA measured radiation levels on the Moon and found that even low levels of radioactivity caused more damage to the body.

To test radioactive theory, scientists conducted experiments on 44 mice to see the long-term effects of the weightless state and radiation simulating space conditions on the cardiovascular system. The test lasted 6 months, with the weight and size of the mouse body so similar to humans in 20 years in the universe.

The results show that equivalent radiation conditions in the universe cause vascular endothelial dysfunction.

Not only that, many studies have also shown that astronauts suffer from hearing, vision, kidney stones, pulmonary dust, immune system disorders and many other problems.
