Can positional vertigo be prevented?

Positional vertigo cannot be prevented in most cases, according to eMedicineHealth. However, treatments such as using more than one pillow while sleeping, not sleeping on the side of the affected ear, avoiding tilting the head backwards, and slowly arising from bed may help to alleviate symptoms.

Positional vertigo is an inner ear disorder that causes a feeling of spinning, notes eMedicineHealth. It occurs as the result of false signals being sent to the brain when small calcium particles within the inner ear canal that help control balance do not move normally. Moving the head in a certain way often triggers bouts of vertigo, and episodes typically only last a few minutes.
