BPPV happens when tiny calcium crystals (otoliths) in the inner ear get displaced and move into the balance canals. When the head moves, these crystals send wrong balance signals to the brain causing the spinning sensation. Stress and poor sleep don't cause it but worsen the brain's ability to compensate. Treatment: Epley maneuver by a physiotherapist or ENT repositions these crystals and resolves most cases quickly.

Positional vertigo (BPPV) occurs when tiny calcium crystals in the inner ear become displaced and move into the balance canals. When the head changes position, these crystals send incorrect balance signals to the brain, causing a brief spinning sensation. It can occur without any obvious reason, but aging, minor head injury, viral ear infections, prolonged bed rest, or inner ear disorders may increase the risk. Stress and lack of sleep do not directly cause BPPV, but they can make the symptoms feel more frequent or severe.
