Can we retaining proper body functions after prolonged periods in space (weightlessness, etc etc etc can cause complications in the body functions if the said body have been in space for years)..
The human body undergoes a series of changes when exposed to the microgravity environment of space. These include bone and muscle loss, changes in cardiovascular function, and a weakening of the immune system.
Without the constant force of gravity, the body does not need to support its own weight and therefore experiences bone and muscle loss. This can lead to a decrease in bone density and muscle mass, making it difficult for astronauts to perform physical tasks upon returning to Earth.
In microgravity, the heart does not need to work as hard to pump blood against the force of gravity. This can lead to a decrease in heart muscle mass and a decrease in overall cardiovascular function. Astronauts may also experience changes in blood pressure and heart rate in space.
The immune system is weakened in space, making astronauts more susceptible to infections and illnesses. This is due to the decrease in white blood cells, which are responsible for fighting off infection.
Astronauts must undergo rigorous physical training before and during their time in space to combat the effects of microgravity on the body. They also follow a strict diet and exercise routine in space to maintain bone and muscle health. Additionally, astronauts may use specialized equipment such as treadmills and resistance machines to simulate the effects of gravity on their bodies.
