Why Some People Suffer From Motion Sickness—and Which Remedies Actually Work

Motion sickness is a common and often unpleasant experience for many travelers, with symptoms ranging from dizziness and nausea to vomiting and cold sweats. But why do some people suffer more than others, and what can actually help?

The Science Behind Motion Sickness

Motion sickness occurs when the brain receives conflicting signals about movement from the eyes, inner ears, and body. For example, if you’re reading in a moving car, your inner ear senses motion, but your eyes are fixed on a stationary page. This sensory mismatch confuses the brain, leading to the classic symptoms of motion sickness.

Recent research has found that electric vehicles may exacerbate motion sickness for some passengers. The quick acceleration and lack of familiar engine noise in EVs can further disorient the brain, increasing the likelihood of nausea. Notably, even drivers of self-driving electric vehicles are just as prone to motion sickness as passengers.

Who Is Affected?

While almost anyone can experience motion sickness under the right conditions, some people are more susceptible than others. Factors such as genetics, age, and previous experiences can all play a role. For some, symptoms may persist throughout life, while others may only experience them occasionally.

Effective Remedies and Prevention Strategies

Experts suggest several strategies to prevent or alleviate motion sickness:

• Focus on Stable Points: Looking out the window and focusing on a stable object (like the horizon or the wing of an airplane) can help reduce conflicting signals to the brain.

• Choose Your Seat Wisely: Sitting in the front seat of a car, over the wings in an airplane, or on the deck of a boat can minimize motion sensations.

• Avoid Triggers: Try to avoid reading, facing backward, or looking at other sick passengers. Also, steer clear of strong odors and heavy or spicy foods before and during travel.

• Get Fresh Air: Open a window or use a fan to get fresh, cool air, which may help relieve symptoms.

• Chewing and Ginger: Chewing gum, snacking, or using ginger (in tablet or fresh form) may help some people, though scientific evidence is mixed.

• Rest Your Eyes: Closing your eyes or napping can help resolve the sensory conflict, especially in environments where visual cues are limited.

Medications and Alternative Treatments

• Over-the-Counter Medications: Antihistamines such as dimenhydrinate (Dramamine®) and diphenhydramine (Benadryl®) are commonly recommended for motion sickness. However, they may cause drowsiness.

• Prescription Options: For severe cases, prescription medications and skin patches are available, but these should be discussed with a healthcare professional due to potential side effects.

• Alternative Remedies: Some people use anti-nausea wristbands or acupressure, though evidence for their effectiveness is limited.

The Future of Motion Sickness Treatment

Emerging therapies, such as mild electrical stimulation to the scalp, are being researched and may offer new hope for sufferers in the future. However, these are not yet widely available.

“In most cases, motion sickness can be prevented by behavioral and environmental modifications. Pharmacotherapy should be considered for more severe cases and is most effective when combined with these strategies.”
