Why do you get dizzy on swings?

Getting dizzy on swings is primarily due to the effects of motion on the vestibular system, which helps regulate balance and spatial orientation. As the swing moves back and forth, the rapid changes in position and speed can confuse the brain, leading to a disorientation of sensory signals. This disorientation can trigger dizziness or vertigo as the brain struggles to process the conflicting information from the inner ear, eyes, and body. Additionally, swinging can alter blood flow and pressure in the brain, further contributing to the sensation of dizziness.
