Why do you get dizzy when you bend your head back?

Dizziness when bending your head back can be caused by changes in blood flow to the brain, which may occur due to the position of your neck. This movement can compress blood vessels or affect the vestibular system, which helps regulate balance. Additionally, issues with the inner ear or underlying medical conditions, such as cervical spine problems, may contribute to the sensation of dizziness. If this occurs frequently, it's advisable to consult a healthcare professional for a thorough evaluation.
