Motion sickness is a common problem experienced by many travellers, especially while reading books or using mobile phones during car journeys. The condition can cause nausea, dizziness, sweating, headaches, and vomiting, making what should be an enjoyable road trip uncomfortable. Doctors explain that the issue is not related to a weak stomach but is caused by a conflict between signals received by the brain from different senses.

According to Dr Amit Prakash Singh, consultant in internal medicine at CK Birla Hospital, Delhi, motion sickness occurs when the brain receives conflicting information from the eyes and the inner ear. While travelling, the inner ear detects movement, turns, and changes in speed, but the eyes may remain focused on a stationary object inside the vehicle, creating confusion in the brain’s balance system.

This sensory mismatch becomes stronger when passengers read books or scroll through phones while travelling. The eyes remain fixed on a nearby object, while the inner ear continues to sense the motion of the vehicle. This difference between visual and balance signals can intensify symptoms such as nausea and dizziness, which is why experts advise avoiding screen use or reading during journeys.

Certain groups are more likely to experience motion sickness, including children, pregnant women, people with migraines, and those who have experienced the condition earlier. Dr Singh said these individuals are more sensitive to the sensory imbalance that triggers discomfort during travel.

Doctors suggest several ways to reduce motion sickness symptoms. Travellers can sit in the front seat, look at distant objects outside the vehicle, keep their head steady, and ensure proper ventilation by allowing fresh air into the car. Avoiding heavy or oily meals before travelling and staying hydrated can also help reduce nausea and discomfort.

For people who frequently experience motion sickness, medication may be considered after consulting a doctor. Avoiding reading or scrolling, maintaining a stable posture, and focusing on the outside environment can make journeys more comfortable. Understanding the reason behind motion sickness can help travellers manage symptoms effectively and enjoy road trips with fewer disruptions.
