Why Does Motion Make Me Feel Sick?

Have you ever experienced an unpleasant feeling of nausea or dizziness while traveling on a bus? This common ailment, known as motion sickness, affects many individuals and can significantly diminish the enjoyment of otherwise enjoyable journeys.

Motion sickness arises from a sensory conflict that occurs within the inner ear and the eyes. As the bus moves, the inner ear detects the changes in motion and sends signals to the brain. Simultaneously, the eyes provide visual information about the bus’s surroundings.

When these signals conflict, the brain becomes confused and interprets the information as a mismatch between the body’s actual movement and the perceived movement. This sensory dissonance triggers the release of neurotransmitters that can cause nausea, vomiting, and dizziness.

The jarring rhythm of the bus, with its constant swaying and bouncing, exacerbates this sensory conflict. The repeated acceleration and deceleration create unpredictable and conflicting signals, further confusing the brain and intensifying motion sickness symptoms.

Other factors that can contribute to motion sickness include:

• Susceptibility to vestibular disorders (conditions affecting the inner ear)
• Genetics
• Age (children and young adults are more prone to motion sickness)
• Certain medications
• Anxiety or stress

While motion sickness can be a frustrating and unpleasant experience, there are several strategies to mitigate or prevent its symptoms:

• Choose a seat facing forward to minimize the visual-vestibular conflict.
• Look at a fixed object in the distance, such as the horizon or a stationary tree, to stabilize the eyes.
• Avoid reading or using electronic devices that can create additional visual conflict.
• Take over-the-counter anti-nausea medications before your journey.
• Try ginger supplements or candies, which have anti-nausea properties.
• Consider wearing motion sickness bands or earplugs that apply pressure to specific points to reduce nausea.

If motion sickness persists or becomes severe, seeking medical attention is advisable to rule out any underlying medical conditions that may contribute to the symptoms.
