Reasons Why Spaceflight is Bad For The Human Body:

The idea of space travel isn’t all cool tech, new planets to explore and lasers as the Hollywood movies make it out to be. In fact, space is a harsh, cold void of dark matter with no mercy for those that go beyond their natural environment because of curiosity or hubris. It is no place that you venture into without a thorough game plan on how to survive with multiple escape plans if things go wrong. Here are some ways that space is out to kill you:

Space radiation:

This must be the #1 reason why space is deadly to the human body. The radiation that comes from the sun in terms of UV radiation is far more deadly without the protection of an atmosphere. Proof of this occurrence is evident with the astronauts that stay in the International Space Station for long periods at a time as they tend to develop cancers and even cataracts due to the random genetic mutations that occur due to radiation exposure.

Reliance on technology:

As space is not the environment that we have adapted to, we have to use lots of technological inventions to compensate for our biological shortcomings. One clear example is the use of artificial gas exposure to simulate the air exposure that we have here on Earth (21% of which is oxygen). The only problem with this is that this will all be computer regulated and your life will constantly depend on that computer not malfunctioning.

Blood pooling:

Due to the lack of gravity (even in the microgravity environment of a spaceship) blood tends to pool around the torso and away from the extremities (legs and arms). This is because gravity aids the pumping of blood to the limbs via arteries, without the extra stimulus the heart doesn’t exert enough force to get blood to the limbs effectively. This is detrimental as this means the limbs won’t be receiving the nutrients and oxygen that they require.

Bone and muscular atrophy:

The other effect of a lack of gravity of course is that the bones and muscles no longer have the stimulus that they require to hold on to adequate muscle mass or bone density. Even those inactive on earth will get more of a training stimulus than sedentary astronauts on a spaceship, hence why NASA recommends up to 2 hours of exercise every day for astronauts aboard the International Space Station.

Conclusion:

As you can see space is not a kind environment at all and we need to devise ways in which we can be prepared to handle these challenges. In fact, I have written an eBook on this very topic! If the idea of finding solutions to these problems interests you, then please check out the eBook using the following link: https://www.amazon.com/dp/B09X1TRPWC
