Russian cosmonaut complained of fatigue from the enclosed space

The astronauts who were selected and training and was allowed to fly, unknown to claustrophobia, but the orbit may develop fatigue from the enclosed space, said Russian cosmonaut Ivan Wagner.

"There is no such that there was a strong desire to go out ... there is more accumulated fatigue from a closed space," he said during a linkup with the ISS.

While Wagner noted that if the person who somehow got into the cosmonaut corps, there is claustrophobia, to hide it he will not succeed. This fear will become clear during training and workouts on the Ground.

In addition, the cosmonaut noted that a person with claustrophobia would be very difficult to work in space because the suits are a little space ship, inside of which very little space.
