Seasickness

Seasickness, or motion sickness, is a disorder caused by the movement of a vehicle, usually a ship or boat. It manifests itself in the form of nausea, dizziness, sweating and sometimes vomiting.

Motion sickness often occurs when a person first finds himself on the open sea. It is caused by a conflict between the visual perception of movement and the vestibular apparatus, which is responsible for balance. The brain receives conflicting signals about body movement.

To prevent motion sickness, it is recommended to look at the horizon rather than the deck of the ship, take medications an hour before boarding the ship, and avoid fatty and spicy foods. It is also useful to stay in the central part of the boat, where there is less rolling. Motion sickness usually goes away after a few hours or days as you get used to the movement.

Seasickness is a condition in which a person experiences discomfort such as nausea, dizziness, headache and general weakness as a result of seasickness caused by deck motion. This condition can lead to a deterioration in a person's quality of life, for example, to the inability to undertake long sea voyages on board a ship, and can also cause loss of work related to maritime activities if this negatively affects the quality of work. However, steps can be taken to reduce the likelihood of seasickness and reduce its intensity.

Causes of the disease

Sea sickness is the result of exposure to specific signals from the vestibular and auditory system on the central nervous system. In other words, seasickness occurs as a result of a malfunction in the system of perceiving the position of the body in space. Factors that can trigger the development of this condition are the following:

The sea and the wave of the ship's movement. All of the above symptoms usually occur when the vestibular apparatus is exposed to changes in the acceleration of the vessel moving up and down, turning left and right. When the central nervous system cannot correctly interpret signals from this organ system, dizziness and other symptoms occur. The more the ship rolls, the more seasickness manifests itself.

Sea water temperature. It often happens that people develop seasickness after drinking alcohol. In this case, this condition is caused by a lack of oxygen for brain tissue. In addition, seasickness may occur in cold or hot weather with low blood pressure, visual fatigue, vega
