Try not to eat when you are seasick for the following reasons: first, the patient may have nausea and vomiting when he is seasick, and then eating will easily lead to nausea and vomiting again, and a large amount of food will easily enter the trachea leading to aspiration, and there is a possibility that it will become a foreign body in the trachea, especially for small children, which may lead to very serious consequences. Secondly, nausea and vomiting may exist when you are carsick, and eating again will increase the burden on the gastrointestinal tract leading to more vomit, making it more difficult for the patient, so it is best not to eat when you are carsick. If you feel hungry, you can eat something light and try not to eat greasy half an hour to an hour before the ride. If you have a past history of motion sickness, you can take a motion sickness pill half an hour before the ride, which may be able to reduce the performance of motion sickness.
