Curvy roads and looking at your phone make you nauseous? Find out why

Many of us have experienced it: during a car trip, while reading or using our phone in the back seat, we get nauseous, dizzy, or have a headache. The trip is ruined.

But help may come from an unlikely source: astronauts. They too face motion sickness during space missions. Scientists studying the phenomenon in space hope to help not only space exploration, but also people on Earth.

A 2020 study found that 59% of participants had experienced motion sickness in the past 5 years. For astronauts, it's even more common, with about 70% experiencing serious symptoms, despite medications like scopolamine.

According to researcher Aaron Allred of the University of Colorado, one of the most widely accepted theories is vestibular sensory conflict, a mismatch between what we sense through the vestibular system and what our brain expects to sense. For example, when you read in a moving car, your brain doesn't "anticipate" the motion, causing dizziness.

In contrast, the car driver sees the road and anticipates movement, so he rarely feels motion sickness.

In a 2025 study, participants were placed in a device that simulated lateral movement while receiving electrical stimulation to the vestibular system. Some stimuli were used to alleviate symptoms, while others were used to worsen them.

Results: incentives aimed at reducing the disease decreased it by 26%, while those that worsened it increased it by 56%.

This technology is not yet available to the public. So the main advice is: avoid sensory conflict. Don't read in the car, look at the horizon, or close your eyes.

If symptoms persist after you stop traveling, it could be something more serious. Some conditions, such as vestibular migraines or balance system disorders, can mimic motion sickness. A proper diagnosis requires medical attention.

Hope lies in research for astronauts, which can translate into solutions for travelers on Earth. / Discover Magazine - Syri.net
