When you have recovered, repeat step 1, but when you stop this time, immediately spin the same number of times to the left and stop. You should now find that when you stop, you do not feel as dizzy. In the second situation, you have begun to move the endolymph in opposite directions and the two effects of motion tend to cancel out. Frequently, astronauts in orbit become dizzy because, without the earth's strong gravity, they are constantly falling. Remember that sinking feeling in your stomach when your car hits a dip in the road or you experience a dip on a roller coaster ride.
Scuba divers have a similar experience.
Buoyancy affects the otolithic organs in the same way as the lack of gravity does. Therefore, it is easy for a diver to become disoriented underwater and not know which way is up or down without other visual cues. Inc. All rights reserved.
