While altitude sickness and motion sickness may share similar traits, they are two different illnesses. There are a variety of symptoms that present with altitude sickness. If left untreated, it can become a serious health problem quickly. It occurs when one ascends to a higher altitude too quickly. Altitude sickness is not all that different, it is also known as Acute Mountain Sickness. It mostly happens to people who travel by land, sea, and air. We know that motion sickness happens when your inner ear does not sense the movement that your eyes are seeing. South Georgia and the South Sandwich Islands.These medications tend to be dehydrating, though, so drink plenty of water.
A dose is usually recommended about an hour prior to setting sail, and as needed at sea. Consider an over-the-counter medication to prevent or minimize motion sickness.Staying leeward (the side of the ship that’s sheltered from the wind) will ensure that an unpleasant experience doesn’t get even worse. If you have to vomit "over the side,” though, check the direction of the wind and waves.
This simple approach allows for peace of mind by eliminating some of the panic of getting seasick. The closed-in quarters below deck magnify the vessel’s motion and worsen symptoms.
Stay on deck, even if it’s raining, because the fresh air is often enough to speed recovery. Most people find that being busy keeps their minds off their discomfort. Drink water, low-acidity juices like apple and carrot, or clear soup, and avoid milk and coffee. Seasickness and related medications cause dehydration and headaches.

Seasickness usually occurs in the first 12 to 24 hours after “setting sail,” and dissipates once the body acclimates to the ship's motion. Agitated by this perceptual incongruity, the brain responds with a cascade of stress-related hormones that can ultimately lead to nausea, vomiting, and vertigo.Īdditionally, an affected person’s symptoms can be magnified by the strong odors of things like diesel fumes and fish. But, since the cabin moves with the passenger, one’s eyes register a relatively stable scene. Inside the cabin of a rocking boat, for example, the inner ear detects changes in both up-and-down and side-to-side acceleration as one’s body bobs along with the boat. Seasickness is a result of a conflict in the inner ear, where the human balance mechanism resides, and is caused by a vessel’s erratic motion on the water. If you've ever had motion sickness when traveling by car, plane, or amusement park ride, you may be more susceptible to seasickness while aboard a vessel. An individual's susceptibility to seasickness is highly variable. 
One of the least pleasant aspects of going to sea is the possibility of getting seasick. A large wave towering astern of the NOAA Ship Delaware II in 2005 while crossing the Atlantic Ocean's New England Seamount Chain.
