Space Travel: Find Out What Traveling To Space Does To Your Body
As reports about astronauts traveling to deep space, exploring Mars and even transferring humans to another planet flood the media, people should also consider what space actually does to the human body.
According to their study, among the major effects of traveling to space is the weakening of bones. Since an astronaut's bones do not need to support as much weight and are not subjected to handling the usual stress in microgravity, the calcium in their bones will tend to be broken down and released to the blood stream, reflecting a decrease in bone density.
Some scientists even say that the body breaks bones down faster than building them up in microgravity. The bone density could decrease by 1 percent in a span of one month, which may lead to bone fracture when astronauts get back to Earth.
Microgravity could also lead to decrease in muscle strength and volume due to lack of activity even with regular exercise.
According to another research involving 27 astronauts, with an average of 108 days spent in space, 22 percent of them showed a flattening at the back of their eyeballs. This condition is found among patients with Idiopathic Intracranial Hypertension.
Meanwhile, despite the overwhelming good feeling of being able to travel in space, the astronaut's heart still would not be completely happy with the effects of microgravity. Study says that the heart could lose its mass in space and can turn into a slightly spherical shape due to a decrease of blood in the body.
This could mean a decrease in blood pressure and a possibility for the astronaut to feel dizzy or faint when he comes back to Earth.
