Motion sickness is the term attributed to physiologic responses to travel by sea, car, train, air and virtual reality immersion. Anyone with a functional vestibular system can develop motion sickness depending on the individual threshold to the severity of the stimulus. Other risk factors that make a particular individual more susceptible are :
Age—children aged 2–12 years are especially susceptible, but infants and toddlers are generally immune. Adults >50 years are less susceptible to motion sickness.
Sex—women are more likely to have motion sickness, especially when pregnant, menstruating, or on hormones.
Migraines—people who get migraine headaches are more prone to motion sickness, more so during a migraine episode
