Motion sickness refers to a set of symptoms—such as nausea and dizziness—that can occur when traveling by boat, plane, or car. It is particularly common in children, but not exclusively; even animals can be affected. The condition arises from a mismatch between the movement detected by the eyes and the lack of motion sensed by the inner ear.
Homeopathy can be especially helpful in these situations, as it helps relieve symptoms without causing drowsiness or other side effects.
