Spinning tunnels can make you dizzy, and research points to a sensory mismatch — but no study has directly tested the tunnel itself.

The basic mechanism has some indirect support. Other research shows that when your eyes and inner ear send mismatched signals about movement, it can make you dizzy and unsteady, which fits the idea that a spinning tunnel throws your senses out of sync. Another study found that moving visual patterns can alter how quickly people react to keep their balance after a fall, though it didn't test spinning tunnels or the feeling of vertigo itself. For the specific claim that a spinning tunnel can cause vertigo, there's related evidence that watching a moving visual scene can make you feel like you're moving — a sensation tied to dizziness — but again, the study didn't have people walk through a tunnel. When it comes to loss of equilibrium, we couldn't find studies in our databases. The big caveat: none of this directly tested the walk-through-a-spinning-tunnel experience; it's all proxy evidence for the underlying mechanism.
