Land sickness is a temporary sensation of motion that continues after returning to stable ground from a moving environment, such as a boat. This experience is a real adjustment for the body.
Understanding Land Sickness
Land sickness, also known as “mal de débarquement,” occurs when the brain struggles to re-adapt to a stable environment after prolonged motion exposure. Common symptoms include sensations of rocking, swaying, or bobbing, alongside unsteadiness, dizziness, and sometimes nausea. Unlike typical motion sickness, which arises from motion itself, land sickness is a “lack-of-motion” sickness.
The inner ear’s vestibular system is crucial for balance. While on a moving vessel, the brain adapts to constant motion. Back on solid ground, the brain may continue to anticipate this learned motion, creating a conflict between the body’s balance system, visual input, and sensory receptors. This sensory mismatch causes the lingering feeling of movement.
Typical Duration and Influencing Factors
The duration of land sickness varies, typically lasting from a few hours to a couple of days. Most sensations resolve within 24 to 48 hours as the brain recalibrates. However, symptoms can sometimes persist longer.
Several factors influence how long land sickness lasts. The length and intensity of motion exposure play a role, with longer voyages potentially leading to more pronounced sensations. Individual susceptibility also contributes, as some people are more prone to these after-effects.
Women aged 30-60 and those who frequently experience migraines tend to be more susceptible to persistent forms. Overall health, stress levels, and sleep quality can also influence symptom intensity and duration.
When sensations persist for more than a few days or a week, it’s often called Mal de Débarquement Syndrome (MdDS). This is a rarer, more persistent neurological disorder. A distinguishing characteristic of MdDS is that symptoms often temporarily improve with re-exposure to passive motion, such as riding in a car.
Coping with Symptoms
Several practical steps can help alleviate land sickness symptoms. Focusing on a stable, fixed point, like the horizon, provides consistent visual input, reducing sensory conflict. Staying well-hydrated is also beneficial.
Eating light, bland meals and avoiding heavy, greasy, or spicy foods, alcohol, and caffeine can help settle an upset stomach. Fresh air, by going outdoors or opening a window, can provide relief. Avoiding activities demanding visual focus on moving objects, such as reading or using electronic devices, may also be helpful.
Finding a quiet environment and resting aids the body’s re-adaptation. Some find consuming ginger (supplement, ginger ale, or candies) helps with nausea. Gentle, controlled movements like walking or short car rides can sometimes assist the brain in recalibrating.
When to Seek Medical Attention
While land sickness often resolves on its own, medical consultation is appropriate if symptoms persist for more than a few days to a week. This is especially important if symptoms transition into Mal de Débarquement Syndrome.
Severe or worsening symptoms, including extreme vomiting, profound dizziness leading to falls, or any new and unusual sensations, warrant immediate medical evaluation. Seek professional advice if land sickness significantly interferes with daily activities or quality of life. Typical motion sickness medications are generally not effective for land sickness or MdDS. A healthcare provider may recommend specific therapies, such as vestibular rehabilitation, to help the brain re-learn balance.
