Find answers to medical questions from experts about motion sickness and symptoms of anxiety disorder.
Question: I’m been driving for over 15 years since I was 21, but each time I am a passenger in someone else’s car, I get motion sickness. What causes this nauseous feeling? Why do I only get it when I don’t drive? What can I do to prevent this?
Answer: Motion sickness symptoms such as nausea and vomiting may occur when there is a conflict between your eyes and inner ears. A mismatch of information between the eyes and vestibular system will confuse the brain and result in motion sickness. The vestibular system is a network of nerves, channels and fluids in your inner ear, which helps control balance.
As a driver, your brain anticipates and reconciles what you see and feel through your movement of the steering wheel. Although it is generally agreed that controlling a moving vehicle greatly reduces the likelihood of motion sickness, few studies have addressed this issue directly, and the theoretical explanation for this phenomenon is not completely clear.
Mild symptoms of motion sickness can usually be improved by the following techniques:
You should also avoid eating a large meal or drinking alcohol before travelling. Keep hydrated throughout the journey by drinking water. If you are prescribed with motion sickness medication, take them before you start the journey.

Question: These days, even the most ordinary situation, like an overflowing inbox, makes me anxious. My breathing gets short, my palms get sweaty, and I just want to escape from the office. How can I control this? Is there a cure for my anxiety? I am in my mid-40s.
Answer: Having some anxiety symptoms occasionally is a natural response to the stressors we commonly face in life and actually serves to warn and protect us from danger. It is only when anxiety symptoms are severe, long-standing and interfere with our daily functioning that it becomes a ‘disorder’. This then would require treatment.
The most common example of such a disorder is Generalised Anxiety Disorder (GAD), in which one becomes easily worried about many things throughout the day for a period of more than six months. As a result, the person cannot function in his or her work/studies.
Another example is panic disorder, in which there are frequent recurring “anxiety attacks” (short episodes of severe anxiety symptoms, including palpitations and shortness of breath), as well as anticipatory fears of subsequent ‘attacks’. While these symptoms are not life-threatening, they may affect the person’s daily activities or cause him to turn reclusive.
In your case, try making some changes to your lifestyle. Ensure that you have sufficient sleep and adequate exercise. Certain foods and beverages such as caffeinated beverages can cause anxiety-like symptoms such as tremors and palpitations, so avoid or consume these in moderation.
If you are still worried, visit a doctor for an assessment. A person diagnosed with anxiety disorder can be helped with both medication and psychological therapies.
