Long car trips, jaunts on a boat, or even a smooth plane ride ¨C for someone prone to motion sickness, all can be miserable experiences. Up to 80% of people have experienced motion sickness in varying degrees, but few know what causes it.
Motion sickness is the result of the inner ear and the brain receiving mixed signals. For example, an airplane passenger feels the plane moving but does not see his surroundings change. His inner ear tells his brain that he is in motion, but his eyes disagree. As a result, the passenger feels queasy. Another common cause of motion sickness is reading in a car. In this case, a passenger¡¯s inner ear is telling her that she is moving, but her eyes are only focused on the immobile book or magazine.
The scenario of motion sickness can also be reversed. Large screen movie theatres, like IMAX, will advise their audiences that if they become dizzy or nauseated during the movie, they should simply close their eyes. In this example, the movie makes the viewer feel like he is piloting a rocket through space, when, in actuality, he is only sitting in a chair. This contradictory state can cause motion sickness. Even watching something spin or swing for extended periods of time can make individuals feel ill.
Symptoms of motion sickness generally include dizziness, headaches, nausea, and vomiting in various degrees. Some individuals feel just slightly uncomfortable, while others may be affected for hours or days after the trip. Either way, motion sickness is not fatal or even particularly serious.
Despite its lack of seriousness, motion sickness is still bothersome, especially for those who are prone to it. Migraine sufferers and people who have problems with inner-ear pressure (frequent ear popping or clogging) are more likely to suffer from motion sickness than anyone else. An individual with Meniere¡¯s disease (having an excess of pressure in the inner ear) also has increased susceptibility to motion sickness.
Changing certain factors can help alleviate motion sickness. Poor ventilation can exasperate the symptoms, so an open window or standing on the deck of a boat is advisable. Additionally, eating spicy, rich foods and consuming alcohol before a trip can increase an individual¡¯s susceptibility for motion sickness, so both should be avoided.
Other factors of motion sickness cannot be changed, but being aware of their effect can aid in preventing discomfort. Some individuals are genetically predisposed to motion sickness because of their parents or even their heritage. Also, woman are more likely to suffer from motion sickness during their pregnancy than other times, though the symptoms of motion sickness and morning sickness are admittedly similar. Lastly, the more emotionally charged a person is (either with fear or excitement), the less likely they will become sick.
If motion sickness becomes more than just an annoying feeling while traveling, an ear, nose, and throat doctor can be consulted. Although no cure for motion sickness exists, evaluating a patient¡¯s medical history can offer insight into why he has severe travel problems. Medications, infections, injuries, etc. can all contribute to the intensity of motion sickness.
Additionally, over-the-counter drugs can help with some of the symptoms of motion sickness, and a pharmacist can make specific recommendations. Another treatment option is more natural remedies, such as ginger or acupressure. Ginger is known to calm the stomach in any situation, so sipping ginger tea can help with any nausea related to the trip. Acupressure bands, created to treat motion sickness, place slight pressure on the inside of each wrist along the Pericardium-6 acupuncture point. Most drug stores carry these bands.
While the mixed sensory messages that cause motion sickness cannot be prevented, the effect they have on an individual can be controlled. Eating lightly, not consuming alcohol, and using medication or natural remedies may all reduce the symptoms and annoyance of motion sickness.
