Humans in Space
The work of Cain ("Spaceflight" Dec 2007) and others have seen the need to understand the hazards and risks of working in a low gravity environment. The general effects on the body of space flight or reduced gravity for example, as may occur on the Moon or during the exploration of Mars include changed physical factors such as decreased weight, fluid pressure, convection and sedimentation. These changes will affect the body fluids, the gravity receptors and the weight bearing structures. The body will adapt to these changes over the time spent in space. There will also be psychosocial changes caused by traveling in the confined space of a spacecraft. Astronautical hygiene (and space medicine) needs to address these issues in particular the likely behavioral changes to the crew otherwise the measures developed to control the potential health hazards and risks will not be sustained. Any decrease in communication, performance and problem solving for example, could have devastating effects.
During space exploration there will be the potential for contact dermatitis to develop in particular if there is exposure to skin sensitisers such as acrylates. Such skin disease could jeopardise a mission unless appropriate measures are taken to identify the source of the exposure, to assess the health risks, and thereby determine the means to mitigate exposure.

Famous quotes containing the words humans and/or space:
“The difference between humans and wild animals is that humans pray before they commit murder.”
—Friedrich Dürrenmatt (1921–1990)
“True spoiling is nothing to do with what a child owns or with amount of attention he gets. he can have the major part of your income, living space and attention and not be spoiled, or he can have very little and be spoiled. It is not what he gets that is at issue. It is how and why he gets it. Spoiling is to do with the family balance of power.”
—Penelope Leach (20th century)
