Motion sickness is caused by the difference between what you see and what you feel when you are in a moving vehicle. You register the moving motions with the motion with your ear. The fluids in your ear send messages to your brain which helps determine your sense of balance. Your ears determine to your brain that you are moving. However, your eyes send information to your brain that you're not moving. The mismatch in the signals coming from this sides and front of your head and makes your brain confused.
Stress hormones like adrenaline race into your head and your stomach muscles give out some electrical jolts and contract faster than usual. This is what usually leads to throwing up.
To reduce the effects of motion sickness:
- Don't travel on an empty stomach. Eat a light meal beforehand. Empty stomachs just increase your queasiness.
- You can give “sea bands” a try. Those are elastic bands worn on your arms with a plastic button that presses down on a special point in your wrist. The art of acupressure states that it reduces motion sickness.
- Also, people try motion sickness drugs, but they can make you drowsy or dizzy
- You can try the method of looking out the window so both your eyes and your ears tell your brain that you are moving
