Coast sickness, also known as seasickness or motion sickness, is a physiological condition that occurs when an individual experiences symptoms of nausea, dizziness, and vomiting due to the motion of a boat or ship on the water. It is a form of motion sickness specific to being on a vessel at sea.
The term "coast sickness" refers to the particular manifestation of seasickness experienced by individuals while traveling along the coast or near the shoreline. It can occur when sailing, cruising, or engaging in any other activity on water close to land.
The underlying cause of coast sickness is a sensory mismatch between what the eyes see and what the inner ear, responsible for balance and spatial orientation, perceives. The continuous bobbing and rolling motion of the boat disrupts this sensory integration, confusing the brain and leading to feelings of discomfort and sickness. Other contributing factors to coast sickness include anxiety, stress, inadequate ventilation, and strong odors.
Symptoms of coast sickness may vary in individuals, ranging from mild discomfort to severe bouts of vomiting. Common signs include dizziness, nausea, sweating, pale complexion, headache, and fatigue. Fortunately, most cases of coast sickness usually resolve once the individual adapts to the motion of the boat or reaches stable ground.
Preventive measures for coast sickness include opting for a comfortable position on the boat, focusing on the horizon or a fixed point on the shore, avoiding excessive alcohol consumption, staying hydrated, and maintaining good ventilation. Medications such as antihistamines, scopolamine patches, or wristbands may also be used to alleviate symptoms or prevent their onset.
In conclusion, coast sickness refers to the specific form of motion sickness experienced by individuals while traveling along the coast or near the shoreline. It is characterized by symptoms of nausea, dizziness, and vomiting
