What cause dizziness?

Answer 1

There are many things that could cause dizzy spells. The person may be suffering from something as simple as dehydration.

Answer 2

Dizziness (vertigo) is caused when the signals from our muscles and inner ear are scrambled on the way to the brain, or when the brain misinterprets them. When those signals conflict with what we see around us, the brain is unable to deal with the conflicting information, and stops sending accurate information about our position in space and our balance.

The most common cause of dizziness is disruption of the signals from our inner ear, which senses body position and transmits that information to the balance center of the brain, which then coordinates the muscles to make corrections. That signal can be disrupted by rapid movement of the head (especially if it is in two planes at the same time) or by infections of the inner ear.

Other causes involve the brain itself, and are usually related to temporary or permanent impairment of its ability to interpret the signals from the body's kinesthetic (balance) sensors. Such impairment can be caused by alcohol, drugs, injury, organic brain diseases, low blood glucose, reduced oxygen levels and restriction of blood to the head.

Answer 3

Well when you are spinning around you are taking photons from too many areas, and that causes the brain overload.
