The reason why we stumble when we are drunk. Alcohol enters the bloodstream and diffuses into the fluid in the semicircular canals of the inner ear. That causes a temporary change in the density and viscosity of the fluid, which can create a mismatch between what your eyes see and what your inner ear senses. It is this mismatch that leads to symptoms such as dizziness, vertigo, and stumbling, especially when you move your head or change position.
