Ergonomics as defined by Wikipedia and spacifically the IEA in 2007….
“Ergonomics (or human factors) is the application of scientific information concerning humans to the design of objects, systems and environment for human use (definition adopted by the International Ergonomics Association in 2007). Ergonomics is commonly thought of as how companies design tasks and work areas to maximize the efficiency and quality of their employees’ work. However, ergonomics comes into everything which involves people. Work systems, sports and leisure, health and safety should all embody ergonomics principles if well designed.(International Ergonomics Association in 2007) It is the applied science of equipment design intended to maximize productivity by reducing operator fatigue and discomfort. The field is also called biotechnology, human engineering, and human factors engineering.” http://en.wikipedia.org/wiki/Ergonomics
Ergonomics is the science of how humans are effected by their environment. Sleep ergonomics or more precisely the ergonomics of sleep is an ill defined concept with scanty references in literature found by this writer. The combination of the science of sleep and the ergonomic studies I have found has been relegated mostly to how the lack of sleep builds up sleep debt, is responsible for great losses in work productivity and is the number one cause for many work injuries.
The Ergonomics of Sleep as will be defined and discussed in this blog is, the ability to lie in repose, where a chosen sleep posture will either enhance comfort allowing the body to relax, or result in physical discomfort, requiring movement to find comfort again. The positions one choses to sleep in defines comfort at this moment and may last a short or longer periods of time. Sleep positions one does not lie in or moves out of relatively quickly, I argue, are positions that would bring about pain or enough discomfort that it activates the brains need to have the body move. This need to move the body and find comfort again is due to a physiological need to avoid pain. This being said I do believe that there are many reasons why one will move in bed. An important one, not sufficiently studied, in my opinion, is the need to avoid pain, by body positional changes necessary to gain relief and find comfort. Hence arises the study of “body sleep positions“, or what I term ”the ergonomics of sleep“.
How can a chosen body position during sleep cause pain and does this influence ability to fall asleep, go deeply into this state, and be able stay there for extended periods of time?
I am not a sleep specialist but do have expertise in ergonomics, anatomy and physiology so my ideas connecting the various sciences will be bolstered in time and supported by sleep and psychological sciences as I write. Please comment and add to the discussion as you deem fit.
All comments will be seriously considered and are appriciated.

And if tonight my soul may find her peace
in sleep, and sink in good oblivion,
and in the morning wake like a new-opened flower
then I have been dipped again in God, and new-created.
