Do I need to be perfectly healthy to fly in space?

The main problems during space flight are considered motion sickness, fatigue, dehydration, loss of appetite and back pain

The astronauts can perform on the International space station not 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 the 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 flying can affect their health?

In an article published by the British medical journal, argues that the district doctors in British clinics need to be prepared for the fact that in the near future, their patients will begin to wonder whether their body to move space travel.

Only a handful of doctors have sufficient knowledge in the field of space medicine to give expert advice.

Cause for alarm

Previous studies show that spaceflight alter physiology of the human body, but it is unclear how they can affect an imaginary untrained 50-year-old tourist.

Professor David green from kings College, London, believes that in the next two godbole a lot of humans will make a suborbital flight in a specially constructed for this spacecraft. They leave the Earth’s atmosphere in about four minutes will feel weightless, and then again will return to the Earth.

According to green, powerful acceleration and hard braking, which will be essential attributes of these journeys can be for some a big problem.

“It is likely that you will experience nausea, and that’s a cause for alarm. Also may be a problem with all the tourists, experiencing weightlessness, returned to their places before descending to the Ground. During the descent there are tangible overload, and you even lose consciousness,” – says green.

The main problems during space flight are considered motion sickness, fatigue, dehydration, loss of appetite and back pain.

We need to understand what impact can have such flights John Scott, an employee of QinetiQ

During vertical take-off and then rapid descent to the human heart is difficult to deliver blood to the brain at a sufficient level.

“If you have cardiovascular disease, they may occur,” says green.

More research is needed

John Scott, who works at QinetiQ and is a member of the working group on investigation of conditions in outer space during space Agency the UK, is studying the impact of overload on the pilot jets.

“In extreme cases, someone may cope with congestion in 3G, but someone with 6G. But some average over all does not exist. It would be great if doctors in clinics can give advice to the patients,” says Scott.

Researchers in the United States consider how can tolerate overload certain segments of potential space tourists. According to Scott, it is necessary to collect information about the individual characteristics of different groups depending on their age and health, space companies could make decisions on the admission of tourists to the flights.

“The necessary balance between respect for safety and the development of space flight. Additional information will help us to find this balance,” says Scott.
