motosairaus

Motosairaus is a term of Finnish origin that translates to "motor sickness" or "motion sickness." It refers to the unpleasant symptoms that can arise when there is a conflict between sensory information received by the brain during movement. Specifically, it occurs when the inner ear, which is responsible for balance and spatial orientation, detects motion, but the eyes do not see the expected visual cues of movement.

The primary symptoms of motosairaus include nausea, vomiting, dizziness, cold sweats, and a general feeling of malaise. These symptoms can be triggered by various forms of transportation such as cars, boats, airplanes, and even amusement park rides. Factors contributing to motosairaus can include poor ventilation, strong odors, jerky movements, and focusing on stationary objects inside a moving vehicle.

While the exact physiological mechanisms are not fully understood, it is believed that the discrepancy between vestibular (inner ear) and visual input confuses the brain. This sensory conflict can lead to a stress response, which manifests as the characteristic symptoms of motion sickness.

Treatment and prevention strategies often involve minimizing the sensory conflict. This can include looking out at the horizon, avoiding reading or looking at screens inside a moving vehicle, ensuring good ventilation, and avoiding heavy meals before travel. Over-the-counter medications, such as antihistamines and scopolamine patches, are also available and can be effective in preventing or alleviating symptoms. In some cases, behavioral therapies and acupressure may also be used.
