In such a situation, let us know what diseases astronauts get in space, how much time does it take to recover from them…
1. Space anemia
Anemia means lack of blood. Lack of hemoglobin and red blood cells (RBC) in the blood is called anemia. Lack of blood in astronauts in space is called space anemia. In space, the body tries to adapt itself to an environment without any natural air, due to which there is a lack of blood in it.
The body contains up to 70% water and many types of fluids, which flow downwards on Earth, but in space, the blood flows upwards towards the heart through the blood vessels, which reduces the production of blood and RBC in the body and can cause many dangerous problems.
2. Muscles and bones become weak
Staying in space for a long time weakens the muscles and bones. Research has shown that muscle mass can decrease by 20% in just two weeks and by 30% in long missions. Bones weaken by 1-2% every month. This increases the risk of osteoporosis and fractures.
3. Heart danger
4. Effect on the brain
There is no gravity in space, due to which the balance of body and mind is not maintained properly. Many researches have shown that the structure of the brain changes in space. There is a risk of swelling in the nerves and parts of the brain, which affects the ability to think and understand.
5. Radiation hazards
6. Psychological effects
Staying in space for a long time can lead to problems like stress, anxiety, depression, because the body lives in a completely different environment. Due to this, sleep disappears and the body starts facing many mental challenges.
