Seasickness is hardly fatal, but with symptoms such as nausea, stomach cramps and vomiting, it can certainly put a damper on your cruise fun. Motion sickness is thought to be caused by the visual disorientation resulting from being on an object in motion (ship) competing against our body's natural inclination for balance. Whatever the technical cause, the majority of cruisers are familiar with how rough, rocking seas can leave us feeling less than our best.
Mal de mer, however, is not caused by choppy waters alone. Scientific studies have shown that some folks become seasick by suggestion. They simply convince themselves that being on a ship will make them ill. On the other hand, for those who can forget about it, it's often smooth sailing.
Some people have a genuine proclivity for motion sickness and will undoubtedly suffer more during rough seas. According to medical professionals, seasickness is more prevalent in children and women. On the other hand, children under 2 seem to be immune from the ailment. Of equally interesting note, elderly people are less susceptible.
If you have a propensity to motion sickness or are concerned that you might develop symptoms, arm yourself with preventive measures beforehand.
