Seasickness

Virtually anyone can be subject to sea sickness or motion sickness. In fact, 90% of the people have experienced motion sickness at one point in their lives and only veteran ocean sailors seem rather impervious to it.

Cause of seasickness

Motion sickness relates to our sense of spatial orientation, which tells the brain where the body is “in space”: what direction it is moving, what direction it is pointing, and if it is turning or standing still.

This sense of spatial orientation is regulated by complex interaction of the 4 following mechanisms:

The symptoms of motion sickness appear when the brain receives conflicting messages from the 4 systems. And a conflict on board can easily occur: when reading a book on deck your eyes observe no motion, yet your inner ears feel the motion of the yacht due to the waves.

Symptoms of seasickness

The first telltales of such a conflict are often lethargy and a slight drowsiness. But for the victims it will usually start with a nauseous feeling and/or a slight cold sweat. Then these symptoms increase, and the face becomes paler, perhaps even greenish. Any attempt to concentrate on a task will worsen this predicament. The nauseous feeling eventually becomes incontrollable, and leads to - sometimes violent - vomiting.
The victim should be wearing a life jacket and/or be tethered via a safety harness.

Prevention of seasickness

Hours before casting off you could well use an over-the-counter antihistamine such as meclizine or dimenhydrinate and you should - before and during the voyage - avoid spicy or rich foods, alcohol and apples. For longer trips, a prescription medication called Transderm-Scopolamine patch can be worn behind the ear for up to three days at a time. Side-effects of these medications usually consist of sedation and dry mouth. Interestingly enough : Recent studies have shown that ginger root may be useful onboard and is associated with fewer side effects. Yet, only as an anti-emetic and not as a treatment for underlaying motion sickness.

If, despite all these precautions, you still notice the early symptoms with one of you crew, act immediately and :
