Motion sickness (travel sickness) is common, especially in children. It is caused by repeated unusual movements during travelling. These repeated movements, such as going over bumps or round in a circle, send lots of messages to your brain. Your balance mechanisms in your inner ear feel different signals to those that your eyes are seeing which then sends your brain mixed, confusing messages. This then causes the symptom of nausea (feeling sick). Other symptoms you may experience include sweating, drooling saliva, headaches, feeling cold and going pale.

Motion sickness can also be triggered by anxiety or strong smells, such as food or petrol. Sometimes trying to read a book or a map can trigger motion sickness.

Motion sickness is more common in children and also in women. Fortunately, many children grow out of having motion sickness. It is not known why some people develop motion sickness more than others.
