Q

How might NV and motion sickness be related?

A
  • Motion sickness is caused when there is a mismatch between what the eyes see, the inner ear senses, outer ear senses, and what the body feels.
  • Differences in sensations confuses the brain and may lead to NV as part of the body’s protective response (due to unusual movement).
