6. Heart attack
While experiencing a heart attack, many people’s first symptom is dizziness. Once your heart isn’t pumping enough oxygen-filled blood to your brain, you may feel faint, off-balance, and dizzy. A heart attack compromises cardiac function, and in such a situation, the brain is deprived of adequate oxygen, thus producing a lightheaded feeling.
7. Motion sickness
The disfunction between the vestibular systems’ sense of motion and the perceived movement causes motion sickness. Those prone to motion sickness feel nauseous and dizzy while in any form of travel, including ships, cars, and airplanes. When in movement, your muscles feel something, your ear feels something else, and your eyes see other things. The brain of a person who experiences motion sickness cannot take all that at once, and they end up feeling nauseous and dizzy. The dizziness eases immediately the movement stops.
