It would be just perfect if motion sickness didn’t happen at all, but that’s not the case. First thing to do is try to reduce the sensory conflict. If in a moving car try to focus on something inside of it, put down that stationary object. Closing your eyes won’t work as studies show that even blind people are susceptible to motion sickness. Try to focus on the path or horizon ahead, only look straight ahead not to the side as that will make it worse, looking ahead will help to align sense of motion in muscles and inner ear with what is being seen to help minimize the sensory conflict. Sitting in the middle or in in the front seat can also help.
Sitting in the front normally isn’t an option on a plane, but that middle seat still comes into play especially over the wing which is the most calm spot available. Ensuring that there is plenty of cool air blowing on your face will be of great value while trying to breath slowly and deeply, keep in mind that this can dehydrate you so be sure to drink plenty of water.
What you eat before you travel can contribute to motion sickness regardless to manner of travel. It is best to avoid consuming spicy, heavy, fatty foods before travel as studies show that these can contribute to making more people susceptible to motion sickness. Alcohol is also on the avoid list, it is recommended to wait until your feet are on solid ground to indulge.
