Space travel has different health on men than it does on women, according to a recent study jointly conducted by NASA and by the National Space Biomedical Research Institute (NSBRI).
The study, which looked at 477 male astronauts and 57 female astronauts, all of whom had been to space up to June 2013, was conducted in anticipation of longer duration spaceflights in the future. One of these will include a manned mission to Mars in the 2030s.

Six working groups studied data from the spaceflights in which the astronauts had participated. They concentrated on cardiovascular, sensorimotor, behavioral, musculoskeletal, immunological, and reproductive and impacts on these due to having spent periods in space.

In several of these areas, men appear to tolerate spaceflight better than women. Female astronauts tended to  increased heart rates in times of stress and had rates of Urinary Tract Infections (UTIs), as well as rates of cancer caused by , than their male counterparts.

After returning to Earth, women astronauts also had a harder time without fainting–a condition known as orthostatic intolerance–than did men.

Men were found to be more likely to experience loss of hearing and vision as consequences of space travel, the study indicated.

Behavioral the same in both genders.

The study is reported in a recent issue of the Journal of Women’ Health.
