Motion Sickness

What Is Motion Sickness?

Motion sickness is a condition that happens when your brain has trouble processing movement. It occurs when your inner ear, eyes and body send conflicting messages to the brain about how you are moving.

For example, when riding in a car, your inner ear senses motion, but your eyes may be focused on a stationary object, such as a phone or book. This mismatch can trigger motion sickness symptoms.

Motion sickness is not dangerous, but it can be uncomfortable and disruptive. Symptoms usually improve once the motion stops.

What Causes Motion Sickness?

Motion sickness is caused by confusion within the body’s balance system, known as the vestibular system.

Common triggers include:

• Traveling by car, bus or train
• Boat or cruise ship travel
• Flying in an airplane
• Amusement park rides
• Virtual reality or video simulations
  
  

Certain factors can increase the risk of motion sickness:

• Being a child between ages 2 and 12
• Pregnancy
• History of migraines
• Inner ear conditions
• Anxiety related to travel

Common Motion Sickness Symptoms

Symptoms may range from mild to severe and can include:

• Nausea
  
• Vomiting
• Dizziness or lightheadedness
• Cold sweats
• Pale skin
• Fatigue or drowsiness
• Headache
  
  

Symptoms often worsen with continued motion and improve once movement stops.

How Is Motion Sickness Diagnosed?

Motion sickness is usually diagnosed based on symptoms and a person’s history of motion-related discomfort.

Diagnostic steps may include:

• Reviewing travel and symptom history
• Discussing triggers and frequency of symptoms
• Physical exam, if needed, to rule out other causes of dizziness or nausea
  
  

In most cases, testing is not required unless symptoms occur without motion or are severe or persistent.

How Is Motion Sickness Treated?

Motion sickness treatment focuses on relieving symptoms and preventing episodes.

Treatment options may include:

• Over-the-counter medications: Such as antihistamines to reduce nausea and dizziness
• Prescription medications: Including motion sickness patches or oral medications for longer trips
• Lifestyle strategies: Sitting in the front seat, looking at the horizon, and avoiding screens while traveling
• Hydration and light meals: Eating small, bland foods before travel
• Acupressure bands: Which may help some people manage nausea
  
  

A health care provider can help determine the best option based on age, travel type and medical history.

Can Motion Sickness Be Prevented?

Many people can reduce or prevent motion sickness by planning ahead.

Helpful prevention strategies include:

• Choosing seats with the least motion, such as over the wings on a plane or near the center of a boat
• Keeping fresh air circulating
• Avoiding heavy, greasy or spicy meals before travel
• Staying hydrated
• Taking motion sickness medication before symptoms begin
  
  

Children may outgrow motion sickness over time, while others learn which strategies work best for them.

Motion sickness is common and manageable. With the right prevention steps and treatment plan, most people can travel comfortably.

If motion sickness symptoms are severe, frequent or occur without movement, talk with a health care provider to rule out other conditions.
