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:
“...there is hope for a tree, if it is cut down, that it will sprout again, and that its shoots will not cease. Though its root grows old in the earth, and its stump dies in the ground, yet at the scent of water it will bud and put forth branches like a young plant. But mortals die, and are laid low; humans expire, and where are they?”
—Bible: Hebrew, Job 14:7-10.
“When my body leaves me
I’m lonesome for it.
but body
goes away to I don’t know where
and it’s lonesome to drift
above the space it
fills when it’s here.”
—Denise Levertov (b. 1923)
