I’ve always considered dizziness a bit like itchiness ― even though we all recognise the feeling, most of us have no idea exactly what’s happening to our bodies while we’re experiencing it. Healthcare providers and research centre The Mayo Clinic says that dizziness refers to “a range of sensations, such as feeling faint, woozy, weak or wobbly.” But what makes our brain feel like it’s spinning or fading in the first place, and when should it worry us?There are a few factors, but many involve our eyes and earsThe “spinning” type of dizziness that most of us experienced as a child after going on carnival rides or whirling around is the “most common”, neurologist Dr Kevin A. Kerber, who specialises in dizziness, told Scientific American. This feeling actually happens due to changes in our ears, he says. The movements create an “asymmetry in the signals that stem from the vestibular system ― a sensory system situated on each side of the head in the inner ear compartments ― and that are processed in the brain”.
