" Q: Occasionally, when I play video games, I get motion sickness. Why is that? A: The accepted term for that particular variety of motion sickness has been called &amp;quot;simulator sickness,&amp;quot; and despite a few studies to determine its cause, nobody is quite sure why it happens. It doesn&amp;#039;t affect just video-game players. A 1995 report by the U.S. Army Research Institute found that almost half the military pilots who used flight simulators developed aftereffects -- and 10 percent of those respondents had symptoms lasting more than 4 hours. Like motion sickness brought on by planes and boats, simulator sickness seems to occur when there is a disagreement in the brain between what you&amp;#039;re seeing and what your inner ear reports is actually happening. One theory about motion sickness posits that it occurs because the area postrema portion of the brain associates the visual/balance discrepancy with hallucination. Since seeing things that aren&amp;#039;t there is often a sign of poison in the body, the brain tells the body to purge, unleashing the hot dogs. How can you fix it? You might try sitting farther away from the screen so that it doesn&amp;#039;t fill your field of vision. Also, experience often helps you get over it. It seems that after enough exposure to dizzying graphics, your brain learns that you don&amp;#039;t die from poison every time you play a first-person shooter, and it lets you enjoy your fun.
