Do I have full health to fly into space?

Astronauts can spend on the International Space Station no more than six months. And for good reason. The loss of muscle and bone mass in zero gravity during this time is so great that continued presence in space for humans is not possible.

Future space tourists will not go through the same tough training as cosmonauts and astronauts — how flight can affect their health? In an article published by the British medical journal, argued that the district doctors in British clinics need to be prepared for the fact that in the near future, patients will be interested in them, able to move their body space travel. However, only a few physicians have sufficient knowledge in the field of space medicine to give expert advice.

Cause for Concern

Previous studies have shown that spaceflight changing physiology of the human body, but it is unclear how they might affect the imaginary unprepared 50-year-old camper. Professor David Green of King's College in London, believes that in the next two years, quite a few Earthlings will make a suborbital flight in a specially constructed for this spacecraft. They leave the Earth's atmosphere, for about four minutes will experience weightlessness, and then once again return to Earth.

According to Green, powerful acceleration and hard braking, which will be essential attributes of these trips can be a big problem for some. "It is quite likely that you will experience nausea, and this is cause for alarm. It may also be a problem with the fact that all the tourists, experiencing weightlessness, returned to their seats before the descent to Earth. During the descent any tangible overload, and you can even lose consciousness "- says Green.

The main problems during space flight are considered to motion sickness, fatigue, dehydration, loss of appetite and back pain. During the vertical take-off and then a rapid descent to the human heart is difficult to deliver blood to the brain at a sufficient level. "If you have heart disease, they may occur," — says Green.

More research is needed
John Scott, who works at QinetiQ and a member of the working group for the study of conditions in outer space at the UK Space Agency, examines the impact of congestion on the pilot jet. "In extreme cases, someone can cope with congestion in 3G, and someone with a 6G. But some average of all there. It would be great if doctors in outpatient clinics could offer advice to patients, "- says Scott.

Researchers from the United States are considering how congestion can carry certain segments of potential space tourists. According to Scott, it is necessary to gather information about the individual characteristics of different groups depending on their age and health to space companies could decide to admit tourists to fly. "We need a balance between respect for the precautionary and the development of space flight industry. Additional information will help us find that balance, "- says Scott.
