Few things are as unpleasant as seasickness. What you might not expect, however, is to feel sick once you're back on land; although you felt good on the boat.
This phenomenon is known as "land sickness" or "mal de terre" and affects many people who have been on a cruise ship, boat or yacht at sea.
Groundsickness is a problem that often occurs after exposure to passive motion, such as traveling by boat, car, or plane. The official term for land sickness is "mal de terre," which comes from the French language. Many people feel it for a short period of time. In some rare cases, however, the sensation does not end. Then "mal de terre" becomes a chronic condition with a new name. Mal de débarquement syndrome (MdDS) is a neurological disorder that causes a constant sensation of motion that never ends. Symptoms of motion sickness include a constant feeling of rocking or swaying - as if you are on a moving ship - after being on land. Symptoms can be unpredictable, and the sensation of movement usually subsides when a person is in motion again, such as driving or walking.
Fatigue, difficulty concentrating, and impaired balance can also manifest as symptoms when someone suffers from motion sickness. The constant feeling of movement can be exhausting and cause some people to suffer from anxiety and depression as a result. Although we know that the sensation occurs in the brain and is a neurological disorder, the exact mechanism causing the earth disease is unknown. Earth disease is thought to primarily affect the brain's balance and movement centers. It is most common in women between the ages of 30 and 60. There is no specific test for this disease, so the diagnosis is made by exclusion, mainly based on the patient's medical history and described symptoms. All we know is that it is usually triggered by long boat trips or other forms of passive movement, so avoiding them as much as possible can reduce the risk (which may not be very practical). | BGNES
