Motion Sickness: Causes, Symptoms, and Ways to Prevent It

Have you ever felt queasy and dizzy while riding in a car or boat? This common condition, known as motion sickness, can strike during travel, particularly on winding roads or choppy seas. It's a sensory disturbance that affects the body's balance center, and not everyone is susceptible to it.

Why Does Motion Sickness Occur?

Motion sickness arises from a mismatch in the signals sent from three sensory areas to the brain: the visual area, the vestibular system (inner ear balance organ), and the somatosensory system (sense of touch). These sensory areas work together to stabilize the body's balance by sending signals to the brain, which interprets them as information about the body's position and movement.

However, when the signals received by the brain are inconsistent, the brain gets confused, leading to dizziness or nausea. For example, while riding in a vehicle and looking at your phone, your eyes don't sense movement, but your vestibular system does. This discrepancy in signals sent to the brain triggers dizziness and nausea.

What Factors Can Trigger Motion Sickness?

Several factors can contribute to the development of motion sickness. Some individuals are more prone to motion sickness due to underlying medical conditions, age, or physiological changes. For instance, people with conditions like vertigo or Parkinson's disease might be more susceptible to motion sickness.

Children between 2 and 12 years old and adults over 50 are more likely to experience motion sickness compared to other age groups. Additionally, women who are menstruating, pregnant, undergoing hormone replacement therapy, or taking birth control pills are also at a higher risk.

Common Symptoms of Motion Sickness

Motion sickness typically presents with various symptoms, including:

• Nausea
• Fatigue
• Headache
• Dizziness
• Sweating
• Excessive salivation
• Vomiting (in severe cases)

While not dangerous, motion sickness can disrupt your activities. However, the symptoms usually subside once the body's balance is restored.

Effective Tips to Prevent or Alleviate Motion Sickness

There are several preventive measures and remedies that can help alleviate or prevent motion sickness:

• Avoid Reading or Using Mobile Phones: Focusing on the horizon or a fixed point while traveling helps maintain consistent signals sent to the brain, minimizing the discrepancy that causes motion sickness.
• Choose a Stable Seating Position: Avoid seats in the back of the vehicle or near windows, as the movement is more noticeable in these areas. Opt for seats closer to the front and center, where the motion is less pronounced.
• Take Anti-Nausea Medication: Consult with your doctor for appropriate anti-nausea medication to address motion sickness. They can recommend the best medication based on your individual needs and medical history.
• Take Regular Breaks: Stopping for short breaks during long journeys allows your body to regain its balance. Step out of the vehicle, stretch, and take in some fresh air.
• Eat Light Meals: Avoid fatty or greasy foods before traveling and have light snacks during the journey to prevent nausea. Opt for easily digestible options like crackers, fruits, or vegetables.

If you experience severe or frequent motion sickness, seeking medical advice from a doctor is advisable. They can identify the underlying cause and provide personalized recommendations and treatments.
