The Science behind Motion Sickness

Motion sickness can ruin your mood and trip. This occurs because of repeated movements in a vehicle that disturb the motion-sensing organs of the inner ear.

Here are the causes, symptoms, and treatments for motion sickness.

Causes of Motion Sickness

Motion sickness occurs when the sensory organs send mixed signals to your brain, and it can’t make sense of this information. As a result, you feel nauseous, dizzy, and sick.

Our nervous system has different pathways, including the eyes, inner ear, and tissues on the body’s surface. Our body can sense motion when our brain synchronizes the input from all these pathways.

However, when the nervous system receives conflicting messages from the sensory organs, the symptoms of motion sickness occur. For instance, when you’re sitting in a moving car, but your eyes see a static view, the inner ear senses movement left and right. This confusion can create a conflict between the input causing motion sickness.

Symptoms Of Motion Sickness

Some common signs of motion sickness include:

  • hazy vision
  • excessive cold sweat
  • mild headaches and dizziness
  • nausea
  • upset stomach
  • shortness of breath

How To Prevent Motion Sickness

Food Intake Before a Trip

Having a large meal before you get in your car for a long road trip is not a wise decision. It may worsen your sensitivity causing you to be more nauseous throughout the ride.

Pack a light snack or have small meals before and during your trips to minimize and eliminate any chances of throwing up.

Choose the Right Seat

Always sit on the middle seat where the aircraft or vehicle’s movements are less erratic and noticeable. Avoid reading or using your phone as the strain will cause you to lose orientation and make you nauseous.

Fresh Air

Open a window to let in fresh and cool air inside. This can relieve motion sickness slightly by making the space feel less congested, allowing you to breathe more easily, expelling any weird smells from your vehicle.

Window Seats

Looking outside the window of a moving vehicle can create a sense of balance and provide you visual evidence of motion. When you’re traveling by air, try to book a window seat.

Motion Sickness Relief

Symptoms of motion sickness don’t always cease after the motion stops. While these measures can help, it’s always a good idea to pack motion sickness relief drugs.
