It's no coincidence that "nauseous" derives from the Greek word, Vαῦς, for "ship." If you've ever been on a cruise, especially in the middle of the ocean during winter, then you know exactly what we are talking about -- and it's not pretty.
Cruising is supposed to be fun, easy. It's supposed to be a mindless vacation, filled with a never-ending buffet, all-you-can-drink bar tab and open hot tub. But, if you're one of those many vacationers sensitive to the movement of a ship, then you know how easily seasickness can ruin a good time.
Whether you're in a car, on a plane or ferry, the causes and symptoms for motion sickness are the same. Even if you're on huge boat with thousands of other people, it's still possible to become nauseated from a few rocks of the boat. How is that?
According to WebMD, this happens when one part of your balance-sensing system (like your eyes, inner ears and sensory nerves) knows you are moving, but the other parts don't.
For example, if your inner ears, which are responsible for balance, sense you are moving, but your eyes can't make that connection while at sea, your brain senses a "conflict." "That sensory conflict is believed to be the basis for motion sickness," said Dr. Steven Rauch to SELF.
Fortunately, there are plenty of ways to combat seasickness.Here's how things like the type of cabin, food and even posture can influence seasickness. Scroll through above to see our top tips.
