Sensory conflict theory [ edit ] At present a "fully adequate theory of motion sickness is not presently available" but contemporary sensory conflict theory, referring to "a discontinuity between either visual, proprioceptive, and somatosensory input, [en.wikipedia.org]
In the 5th/6th century AD Hesychios Alexandrinos presented an alphabetical dictionary on these different meanings of “ναυτία” and “ναυσία” and their derivatives. [ncbi.nlm.nih.gov]

- Malaise

Gastrointestinal
- Nausea
Seasickness is hardly fatal, but with symptoms such as nausea, stomach cramps and vomiting, it can certainly put a damper on your cruise fun. [cruisecritic.com]
Nausea results when histamine reaches the brain. Some people are more susceptible than others but given the right conditions anyone can become seasick. [mahina.com]
If the cause of the nausea is not resolved, the sufferer will usually vomit, but vomiting may not relieve the feeling of weakness and nausea, which means the person might continue to vomit until the underlying cause of the nausea is resolved. [en.wikipedia.org]
Going on board drunk, hungover, or exhausted can make the problem much worse. [10] Alcohol is especially risky if you plan to take anti-nausea medication, since it can increase the sedative effect or cause dangerous drug interactions. [wikihow.health]
The Latin words “nausea” and “nauseare” were derived from the Greek. [ncbi.nlm.nih.gov]
Psychiatrical
- Fear
It was feared that Hannibal could begin crossing the Rhone at any moment. [ncbi.nlm.nih.gov]
Neurologic
- Headache
As soon as seasick symptoms appear (mild headache, queasiness, sweating, drowsiness, depression) sensory conflict has caused histamine production to start and a more disciplined response is required. [mahina.com]
Thus, afflicted individuals were described as suffering from agitation and pressure on the breast, headaches, and the urge to vomit. [ncbi.nlm.nih.gov]
- Apathy
Other authors, such as Homer and Gellius, stress the occurrence of faintness, apathy, and abulia during seasickness. [ncbi.nlm.nih.gov]
- Confusion
Prolonged vomiting causes dehydration surprisingly quickly, hypothermia (even in the tropics) anxiety, confusion, depression and shock. Once in shock, an enema or IV is the next step to rehydration and your survival. [mahina.com]
Treatment

Available only by prescription, the Scop is preventive, not a treatment, and can cause possible side effects such as dry mouth, blurry vision, drowsiness and dizziness. [cruisecritic.com]
Having dealt with over 400 seasick sailors over the past 42 years at sea, we have become very experienced at prevention and treatment. If you want to avoid seasickness or recover quickly, follow these steps. [mahina.com]

Etiology
A specific type of motion sickness with similar symptoms but a possibly different etiology is space adaptation syndrome (sometimes referred to as space motion sickness). [en.wikipedia.org]
Pathophysiology
The Greek view of the pathophysiology of seasickness was based on the humoral theory of Empedokles and Aristoteles and differed from the Chinese medicine of correspondences, which attributed malfunctions to certain body substances and the life force Qi [ncbi.nlm.nih.gov]

Treatment [ edit ] Many cures and preventatives for motion sickness have been proposed. Devices [ edit ] A motion blocking eyewear device was patented (US patent 6,275,998) [29] to prevent carsickness-related terrestrial motion sickness. [en.wikipedia.org]
There are many over-the-counter medications for preventing motion sickness. [wikihow.health]
Therapy Greek and Roman Approaches Prevention Some ancient authors reflected on how to prevent seasickness, most often emphasizing the importance of becoming accustomed to sea travels. [ncbi.nlm.nih.gov]
