Motion Sickness

Motion sickness occurs when the brain receives mixed signals from the inner ear, eyes, and body, leading to symptoms like nausea, dizziness, sweating, and vomiting. Consult an online GP to get quick advice and treatment options.

When to consult a doctor for motion sickness?

Causes

Motion sickness occurs when the brain receives mixed signals from different sensory systems. Several factors can contribute to this, including:

Conflicting sensory signals: The primary cause of motion sickness is a disconnect between what the eyes see and what the inner ear detects.

Sensitivity of the vestibular system: The inner ear’s vestibular system controls balance and spatial orientation. Some individuals have a more sensitive vestibular system, making them more prone to motion sickness.

Genetics and family history: Research suggests that genetics may play a role, as people with a family history of motion sickness are more likely to experience it themselves.

Migraines and inner ear disorders: People who suffer from migraines or conditions affecting the inner ear (such as Ménière’s disease) are more susceptible to motion sickness.

Anxiety and stress: Stress and anxiety can make symptoms worse, as they heighten sensitivity to bodily sensations.

Hormonal changes: Pregnant women, individuals on hormonal birth control, and those undergoing hormonal fluctuations (such as during menstruation) may be more prone to motion sickness.

Symptoms

Motion sickness symptoms can range from mild to severe and typically include:

Nausea and vomiting

Dizziness or lightheadedness

Sweating

Increased saliva production

Headache

Fatigue

A general feeling of discomfort

Symptoms usually resolve once the motion stops, but in some cases, they can persist for hours after travel

How to manage?

If you frequently experience motion sickness, here are some ways to manage and prevent it:

Choose the right seat: Sit in the front seat of a car, over the wing of an airplane, or in the middle of a boat where movement is less intense.

Focus on a stable object: Look at the horizon or a distant fixed point instead of reading or looking at screens.

Stay hydrated: Drink plenty of water and avoid alcohol or caffeine, which can worsen nausea.

Eat light meals: Avoid heavy, greasy, or spicy foods before travel, as they can trigger nausea.

Use acupressure bands: Wristbands that apply pressure to the P6 acupressure point may help prevent nausea.

Try ginger or peppermint: Both are commonly used natural remedies that may help reduce nausea for some people.

Get fresh air: Open a window or step outside to reduce discomfort when possible.

Take breaks: If traveling by car, stop for fresh air and movement to help reset your balance.

Practice relaxation techniques: Deep breathing and meditation can help reduce anxiety-related motion sickness.

Does anxiety contribute to motion sickness?

Yes, anxiety can heighten sensory sensitivity, making motion sickness worse. Relaxation techniques may help reduce symptoms.

Hola Health provides a convenient way to consult an AHPRA-registered doctor online, 24/7 across Australia.

Clinical note: A telehealth assessment can help evaluate your motion sickness symptoms, discuss preventive strategies, and issue prescriptions for anti-nausea medications if clinically indicated. Motion sickness is generally well-suited to telehealth assessment as it does not typically require a physical examination. If your symptoms include severe or persistent vomiting, significant dehydration, or dizziness that does not resolve after stopping motion, your GP may recommend in-person assessment to rule out other causes. We recommend sharing your consult summaries with your regular GP to ensure continuity of care.

Frequently Asked Questions

What is motion sickness? 

Motion sickness is a common condition in which your brain receives contradictory messages about movement from your eyes, inner ears, and body. It can happen when travelling by car, boat, plane, or any mode of transportation. Common symptoms include nausea, dizziness, sweating, increased saliva production, and, in rare cases, vomiting. Motion sickness is more prevalent in youngsters, but it may affect adults of any age. 

How can motion sickness be managed?

Motion sickness symptoms may be improved by reducing the mismatch between what your eyes see and what your inner ear perceives.

Some techniques that could help are:

Looking at the horizon or a fixed point outside the vehicle.
Sitting in the front seat of a car or on the wings of a plane.
Avoiding reading or using screens while travelling.
Keeping fresh air circulating.
Eating light meals before travelling.

A healthcare provider can discuss management options for frequent or severe motion sickness, including prescription medication (if clinically appropriate).

How can I prevent motion sickness while traveling?

You can reduce the chance of motion sickness by preparing before and during your journey. Helpful tips include:

Sit in the vehicle’s most stable position, such as the front seat of an automobile.
Instead of reading or using a device, focus on a fixed point in front of you.
Keep the air flowing and avoid heavy odours.
Eat a light meal before departing.
Consume adequate water.

If you experience motion sickness frequently, a healthcare professional can recommend extra preventative measures.

Can motion sickness go on its own?

Yes, motion sickness normally improves once the movement stops. Many people feel better after arriving at their destination or leaving a moving environment. Symptoms may recur during future journeys, especially if you are exposed to the same type of movement again. 

Can children get motion sickness?

Yes, children can develop motion sickness, and it is particularly prevalent between the ages of two and twelve. Children may experience nausea, vomiting, dizziness, sweating, or fatigue while travelling. Planning breaks, choosing a suitable seat, and focusing on the distance outside the vehicle may help alleviate problems.

Is motion sickness more common during pregnancy? 

Motion sickness may be more apparent during pregnancy, particularly for those who are already experiencing pregnancy-related nausea. Hormonal changes during pregnancy might alter how the body reacts to activity. If you experience severe nausea or if it interferes with your ability to stay hydrated, consult a healthcare provider.

Are natural remedies effective for motion sickness?

Some natural remedies may help alleviate motion sickness symptoms, but they are not effective for everyone. Strategies such as eating light meals, staying hydrated, and avoiding triggers may be beneficial. If motion sickness occurs frequently or interferes with travelling, a healthcare expert can discuss appropriate management options.
