Aerospace physiology is the study of the effects of high altitudes on the body, such as different pressures and levels of oxygen. At different altitudes the body may react in different ways, provoking more cardiac output , and producing more erythrocytes .
The leans is the most common type of spatial disorientation for aviators.Through stabilization of the fluid in the semicircular canals, a pilot may perceive straight and level flight while actually in a banked turn.
Illusions in aviation are caused when the brain cannot reconcile inputs from the vestibular system and visual system. The three semicircular canals, which recognize accelerations in pitch, yaw, and roll, are stimulated by angular accelerations; while the otolith organs, the saccule and utricle, are stimulated by linear accelerations.
Air Vice Marshal William Kilpatrick Stewart, CB, CBE, AFC, QHP (28 June 1913 – 2 May 1967) was a Scottish researcher in aerospace physiology, senior consultant in physiology to the Royal Air Force, and commanding officer of the RAF Institute of Aviation Medicine.
The first type is more common as pressure reduction from normal atmospheric pressure to a vacuum can be found in both space exploration and high-altitude aviation. Research and experience have shown that while exposure to a vacuum causes swelling, human skin is tough enough to withstand the drop of one atmosphere .

The 20 g centrifuge at the NASA Ames Research Center. High-g training is done by aviators and astronauts who are subject to high levels of acceleration ('g'). It is designed to prevent a g-induced loss of consciousness (g-LOC), a situation when the action of g-forces moves the blood away from the brain to the extent that consciousness is lost.
