Motion sickness occurs when the movement a person visually perceives disagrees with his or her internal sense of movement. When it happens in the car, we call it carsickness, an affliction that seems more prevalent in children.
Is there a cure? Beyond stopping the car, there are really only a couple of ways to treat carsickness…
ADJUST PERCEPTION. Since carsickness is an issue involving perception, there are a few tricks that can help. You can focus on the “horizon or on a distant, stationary object,” according to the Mayo Clinic. Also, try keeping your head still. It also helps a lot of people to drive, rather than riding as the passenger.
DRUGS. A lot of people find that certain over-the-counter antihistamine medications can help. Others can’t tolerate the side effects as they can make you extremely drowsy. If carsickness is particularly severe, there are prescription medications as well.
There is also a lot of folk cures that some people swear by. If the mainstream methods don’t work for you, you could try some of those. Like placing a lunch bag in the waistband of your pants! Really.
