What
makes people dizzy
when they spin?
Rolling down a hill or spinning around in endless circles
causes dizziness or vertigo because hair-like sensory nerve
cells in our ears send wrong messages to our brain.
The motions of our bodies are detected by the vestibular
system found in the upper part of our inner ear. The vestibular
system senses whether we are standing up or lying down.
When we spin in circles or get up too fast from the couch,
we feel dizzy and lightheaded due to the vestibular system's
nerve reactions to these unusual motions.
