If the Earth is rotating why don't we get dizzy?

Answer 1

Our sense of balance comes from fluid in our ears. When you spin in a circle and come to a stop, inertia keeps the fluid in your ears spinning. This makes you feel dizzy.

However, as the earth spins, the fluid in our ears is spinning at the same rate as our bodies. That is, it is moving relative to some non-moving point, but it is not moving relative to our bodies.

That is why we don't get dizzy while spinning in a circle. Only after we come to a stop do we feel dizzy.

That is the same reason we don't feel dizzy while the Earth rotates.

Answer 2

We don't feel dizzy because we, along with everything else on Earth's surface, are rotating at the same speed as the Earth itself. Our bodies have adapted to the Earth's rotation over millions of years, so we don't perceive it as motion. Dizziness typically occurs when there is a mismatch between the signals from our eyes, inner ear, and body position, which is not the case with the Earth's rotation.
