Dizzy

Definition

Feeling dizzy refers to a sensation of lightheadedness or unsteadiness, often accompanied by a spinning or whirling sensation. It is caused by disturbances in the vestibular system, which controls balance and spatial orientation.

Vestibular System:

The sensory system responsible for providing information about motion, equilibrium, and spatial orientation. It includes structures in the inner ear.

Perceptual Adaptation:

The ability of the brain to adjust and adapt to changes in sensory input over time. In the case of an ice skater spinning rapidly without getting dizzy, their perceptual adaptation allows them to suppress the sensations of dizziness.

Balance:

The ability to maintain body stability and control during various movements and activities. Achieving balance involves coordination between multiple systems including vision, proprioception (awareness of one's body position), and the vestibular system.
