Reduce the occurrence of seasickness by medication or training, and minimize boat rides in daily life to avoid stimulus induced vertigo. We should sit in front or in the middle of the boat near the water level, try to avoid reading books and playing with cell phones during the boat ride, do not smoke or sit near smokers, and avoid strong smells, spicy and greasy foods, and alcohol. Under medical supervision, take medication at least 30-60 minutes before the trip to prevent seasickness from occurring. In general, the best way to prevent seasickness is to get out of the boat riding environment, that is, to stop riding the boat, and also to prevent seasickness through moderate training, such as balance training, for example, let the seasick person repeatedly ride the boat several times, so that the body gradually adapt to the environment, and achieve no onset or reduce the symptoms of seasickness.
