Many people experience unease as soon as they sit in a vehicle, often feeling nauseous after travelling a short distance, leading to a ruined trip. This frequent occurrence causes considerable worry for many. Recently, Patna’s popular educator Khan Sir shared a simple, practical solution to tackle this issue, sparking interest among his students for its straightforward approach.
While discussing sense organs with his students, one asked why people feel nauseous in vehicles. Khan Sir explained that this sensation is due to conflicting signals sent to the brain by the ears and eyes. When these signals don’t match, the brain becomes confused and induces vomiting.
Why Car Sickness Causes Vomiting
Khan Sir explained that vomiting occurs when the signals sent by our sense organs to
the brain don’t match. In a car, for instance, the ears detect movement, but if the windows are closed, especially with the AC on, the eyes perceive a stationary environment. This mismatch confuses the brain, which interprets it as a problem in the body. As a result, the brain triggers vomiting to relieve the perceived threat, causing car sickness.
Why Drivers Rarely Experience Car Sickness
While explaining this, a student asked, “Sir, why doesn’t the driver vomit?” Khan Sir clarified that a driver’s body remains highly active during the journey. Their brain, eyes, hands, and feet are constantly engaged, monitoring the road, speed, and traffic. This coordinated activity ensures that the signals from the eyes and ears match, preventing confusion in the brain. As a result, drivers rarely experience dizziness or vomiting.
How To Prevent Car Sickness
Khan Sir shared practical tips to avoid this problem. He suggested sitting near a window and looking outside to align the movement signals from the eyes and ears, reducing nausea. Driving oneself can also help, as the activity keeps the brain engaged with consistent signals.
Additionally, there are medications available to prevent vomiting, which should be taken under a doctor’s guidance. He also mentioned a mobile game that can help by giving the eyes the right sense of motion, alleviating symptoms for some.
Khan Sir’s Recommended Remedy
In a light-hearted moment, Khan Sir recounted his own experience of feeling dizzy while travelling to the hills of Sikkim. He mitigated this by eating Hajmola, which shifted his brain’s focus from motion to taste and chewing. He suggested that engaging the mind in another activity can significantly reduce the feeling of nausea.
