  CSA - Why do astronauts suffer motion sickness in space?
In reflecting on this observation and some of his experience in space life sciences, Dr Watt asked himself whether such a strategy might play a role in the motion sickness, or space adaptation syndrome, that affects about 50% of astronauts at the beginning of a space flight.
TRE was conducted in space during this flight by Canadian astronaut Bob Thirsk.
It was found that astronauts do indeed adopt a torso rotation strategy early in flight and that this may play a role in the motion sickness often experienced early in flight.

A contributing factor to space sickness may be a conflict between astronauts' visual cues and the absence of inner ear and somatic sensations (pressure on your feet or seat).
Space motion sickness is a significant cost in terms of astronaut "down time", reduced work quality, and danger due to impaired co-ordination.
In space, many tests were performed with the astronaut free floating, and alternately wearing a constant force spring harness that provides artificial "down" cues to the shoulders and hips.

 Space adaptation syndrome information - Search.com
Space adaptation syndrome, or space sickness, is what astronauts go through during adaptation to microgravity.
Space sickness was effectively unknown during the earliest spaceflights, as these were undertaken in very cramped conditions; it seems to be aggravated by being able to freely move around, and so is more common in larger spacecraft.
Around 60% of all Space Shuttle astronauts currently experience it on their first flight; the first case is now suspected to be Gherman Titov, in August, 1961 onboard Vostok 2, who reported dizziness and nausea.

 Space Travel 101: Fundamentals of Space Travel
Space adaptation syndrome, also called space motion sickness, is very common in astronauts.
Motion sickness is an equilibrium disorder caused by a mismatch of information between visual input from the eyes and the vestibular apparatus located in the ear.
Another way to handle space adaptation syndrome is through autogenic feedback training, which involves controlling bodily functions that are usually involuntary.

If the motion sickness medication did not help you much, try lying down where your body does not feel the motion as much as when it is standing.

Each study was designed to test the effectiveness of AFT as a countermeasure for motion sickness, and the feasibility of using AFT to prevent or reduce the severity of space motion sickness symptoms in aerospace crews.
Other results showed that tolerance to motion sickness increased only in the group that received AFT, and that these effects were still present three years after this treatment ended.This effect was achieved with 6 hours of training and both sexes learned to increase their tolerance equally.
Included among these are tests of AFT for training cancer patients to suppress the nausea associated with radiation or chemotherapy; improvements in the effectiveness of the treatment of essential orthostatic intolerance (e.g., as in paralyzed patients); the successful treatment of military pilots suffering from intractable airsickness, for whom all other forms of treatment had failed.

 About Motion Sickness and Ways to Prevent It
Another new theory for some cases of motion sickness is the postural instability theory, based on experiments in which motion sickness was preceded by statistically significant increases in several indices of postural sway.
In these cases, motion sickness symptoms were not linked to sensory conflict, but rather to a decreased ability to actively control the body's postural motion.
Scopolamine is the single most effective antimotion sickness drug, consistently providing more protection than any other single medication in clinical trials.(9) It is particularly useful for intense motion or for patients who are very susceptible to motion sickness remedy.

To understand how to prevent space sickness and how our vestibular sense works with other systems, Cullen has been recruited by NASA as a member of the National Space Biomedical Research Institute.
In space, astronauts experience sensory conflict called an "inversion illusion." "An astronaut will feel that he is upright and then will see another astronaut who is oriented the other way and this is very provocative for motion sickness," says Cullen.
