Avoid triggers Don’t travel on small planes, which tend to be worse than larger jets. If you are on a boat, keep towards the centre, where there is less movement. In a car, being the driver helps; the worst place to sit is in the back seat, because it is harder to see out the window. Unfortunately, this is where children typically sit – and people are most susceptible to travel sickness from the age of eight to about 12, says John Golding, a professor of applied psychology at the University of Westminster. Adults who suffer migraines are also more susceptible. Keep your eyes on the horizon The best explanation for motion sickness is the sensory conflict theory, which puts it down to a mismatch between what your eyes see and the information on movement detected by your inner ear. “If you can get a view of the outside and a horizon reference, it’s helpful,” says Golding. “The fewer outside cues you have, the less you can resolve any conflict.” Don’t read or look at your phone.
