Why Do I Get Motion Sickness So Easy?

Motion sickness, also known as travel sickness or kinetosis, is a common condition that affects many people when they are in motion. Motion sickness is caused by a mismatch between the sensory information received by the brain, particularly the inner ear and the eyes, which can lead to symptoms such as nausea, vomiting, dizziness, and headaches. In this article, we will explore why some people get motion sickness so easily.

Inner Ear Sensitivity

The inner ear, also known as the vestibular system, is responsible for detecting motion and maintaining balance. For some people, the inner ear may be more sensitive to motion, leading to an increased risk of motion sickness. This sensitivity can be genetic or due to past experiences, such as a history of ear infections or head injuries.

Visual Distractions

Visual distractions can also contribute to motion sickness. When the eyes are focused on a stationary object, such as a book or phone, while the body is in motion, it can cause a sensory mismatch and lead to motion sickness. This is because the eyes are telling the brain that the body is not moving, while the inner ear is detecting motion.

In addition, visual distractions such as flickering lights or rapid movement in a vehicle can also contribute to motion sickness.

Motion Intensity

The intensity of motion can also contribute to motion sickness. When the motion is sudden or erratic, such as in a roller coaster or turbulent flight, it can be more likely to cause motion sickness. Additionally, long periods of motion, such as a car ride or boat trip, can also increase the risk of motion sickness.

Anxiety and Stress

Anxiety and stress can also play a role in motion sickness. When a person is anxious or stressed, their body produces stress hormones, which can contribute to nausea and other symptoms of motion sickness. Additionally, anxiety and stress can cause a person to focus more on their symptoms, leading to a worsening of symptoms.

Pre-existing Medical Conditions

Certain medical conditions can increase the likelihood of motion sickness. For example, migraine headaches, inner ear disorders, and gastroesophageal reflux disease (GERD) can all contribute to motion sickness. Additionally, some medications, such as antidepressants and antihistamines, can increase the risk of motion sickness.


Motion sickness is a common condition that can be caused by a variety of factors. Inner ear sensitivity, visual distractions, motion intensity, anxiety and stress, and pre-existing medical conditions can all contribute to motion sickness. While there is no cure for motion sickness, there are several strategies that can help reduce symptoms, such as focusing on the horizon, taking deep breaths, and taking medication. If you experience frequent or severe motion sickness, it is important to speak with a healthcare provider to rule out any underlying medical conditions and discuss treatment options.
