motion sickness (DOC) by madhosexy


									Motion sickness
Motion sickness can happen from any kind of movement -- even movement that you' re anticipating.
People tend to get motion sickness on a moving boat, train, airplane, car, or amusement park rides.
Motion sickness usually stops as soon as the motion stops.

Although motion sickness is fairly common and often only a minor nuisance, it may cause problems for
people who travel frequently. Fortunately, the more you travel, the more you get used to the motion.
You can also take precautions to reduce the chance of getting motion sickness.

Signs and Symptoms:
The most common signs and symptoms of motion sickness include:

      * Nausea

    * Pale skin

    * Cold sweats

    * Vomiting

    * Dizziness

    * Headache

    * Increased salivation

    * Fatigue

Motion sickness happens when the body, the inner ear, and the eyes send conflicting signals to the
brain. This most often happens when you are in a car, boat, or airplane, but it may also happen on flight
simulators or amusement park rides. From inside a ship's cabin, your inner ear may sense rolling
motions that your eyes cannot see. On the other hand, your eyes may see movement on a "virtual
reality" ride that your body does not feel. Once a person gets used to the movement and the motion
stops, symptoms may come back (although usually only briefly). Sometimes just thinking about
movement can cause anxiety and symptoms of motion sickness. For example, a person who had motion
sickness before might become nauseous on an airplane before take-off.

Risk Factors:The following are the most common risk factors for motion sickness:
    * Riding in a car, boat, airplane, or space shuttle
     * Young age -- children ages 2 - 12 are most likely to get motion sickness.

     * Being prone to nausea or vomiting

     * Higher level of fear or anxiety

     * Poor ventilation in the vehicle

     * Sitting in the back seat or where you cannot see out the window

Most people who have had motion sickness in the past ask their doctor how to prevent it next time.
Your doctor will ask about your symptoms and find out what usually causes the problem, such as riding
in a boat, flying in a plane, or driving in car. Your doctor doesn' t usually need laboratory tests to make a

Preventive Care:There are several ways you can try to prevent motion sickness:
     * Sit in the front seat in a car.

     * Keep your eyes on the horizon. Don't read.

     * Rest your head against the seat back, to keep it still.

     * Turn the air vents toward your face.

     * Don't smoke.

If you have motion sickness on a plane, try these tips:

     * Avoid big, greasy meals and alcohol the night before air travel.

     * Eat light meals or snacks that are low in calories in the 24 hours before air travel.

     * Avoid salty foods and dairy products before air travel.

     * Sit toward the front of the aircraft or in a seat over the wing.

     * Turn the air vent flow toward your face.

If you have motion sickness on a boat, try these tips:
     * Ask for a cabin on the upper deck or toward the front of the ship.

     * When on deck, keep your eyes fixed on the horizon or land.

Treatment:You can use medication to control your symptoms, but people who travel often may want
to learn to control -- and prevent -- symptoms. Mind-body practices, such as cognitive-behavioral
therapy and biofeedback, may help. Other alternatives to medication include homeopathy,
acupuncture, dietary supplements, dietary changes, and physical exercise.

Medications.Medications or motion sickness may cause drowsiness. Pilots, ship crew members, or
anyone operating heavy equipment or driving a car should not take them. These medications may help
people who have motion sickness:

     * Scopolamine (Transderm Scop) -- most commonly prescribed medication for motion sickness. It
must be taken before symptoms start. It comes in patch form to put behind your ear 6 - 8 hours before
travel. The effects last up to 3 days. Side effects may include dry mouth, drowsiness, blurred vision, and

    * Promethazine (Phenergan) -- take 2 hours before travel. The effects last 6 - 8 hours. Side effects
may include drowsiness and dry mouth.

    * Cyclizine (Marezine) -- most effective when taken at least 30 minutes before travel. It is not
recommended for children younger than 6, and side effects are similar to scopolamine.

     * Dimenhydrinate (Dramamine) -- take every 4 - 8 hours. Side effects are similar to scopolamine.

     * Meclizine (Bonine) -- most effective when taken 1 hour before travel. It is not recommended for
children under 12, and side effects may include drowsiness and dry mouth.

Nutrition and Dietary Supplements.A comprehensive treatment plan to treat motion sickness
may include a range of complementary and alternative therapies. Ask your team of health care
providers about the best ways to incorporate these therapies into your overall treatment plan. Always
tell your health care provider about the herbs and supplements you are using or considering using.

Following these nutritional tips may help reduce symptoms:

     * Avoid spicy, greasy, or fatty meals.

     * Don't overeat.

     * Drink plenty of water.

     * Dry crackers and carbonated sodas (such as ginger ale) help some people avoid nausea.

     * People who tend to have motion sickness may want to eat small, frequent meals.

Herbs.herbs therapy, you should work with your health care provider to get your problem diagnosed
before starting any treatment. You may use herbs as dried extracts (capsules, powders, teas), glycerites
(glycerine extracts), or tinctures (alcohol extracts). Unless otherwise indicated, you should make teas
with 1 tsp. herb per cup of hot water. Steep covered 5 - 10 minutes for leaf or flowers, and 10 - 20
minutes for roots. Drink 2 - 4 cups per day. You may use tinctures alone or in combination as noted.
    * Ginger (Zingiber officinale) standardized extract, 250 mg three times daily as needed, for
symptoms of nausea. Ginger is a traditional remedy for nausea, and some studies show it may help with
motion sickness. Not all studies find that it works, however. Ginger may increase the risk of bleeding,
especially if you also take blood-thinners such warfarin (Coumadin) or aspirin.

     * Peppermint (Mentha piperita) standardized extract, 1 enteric coated tablet two to three times
daily as needed. You may also make a tea of the leaf. Peppermint can interact with some medications,
so ask your doctor before taking it.

    * Black horehound (Ballotta nigra), 1 - 2 ml as a tincture or 1 -2 tsp. of leaves steeped as a tea,
taken three times per day. This is a traditional remedy for motion sickness, but no scientific studies have
been done to test the benefits. Black horehound can interact with Parkinson' s medications.

Acupuncture.Some studies suggest that acupressure may help reduce symptoms of motion sickness
in the same way as acupuncture, although the evidence is not clear. An acupressure practitioner works
with the same points used in acupuncture, but uses finger pressure rather than inserting fine
needles.The acupuncture point known as Pericardium 6 traditionally has been said to help relieve
nausea. It is on the inside of the wrist, about the length of 2 fingernails up the arm from the center of
the wrist crease. Many travel stores sell wrist bands with built-in buttons that apply acupressure to this

Homeopathy.Few studies have examined the effectiveness of specific homeopathic remedies. A
professional homeopath, however, may recommend one or more of the following treatments for
motion sickness based on their knowledge and clinical experience. Before prescribing a remedy,
homeopaths take into account a person' s constitutional type -- your physical, emotional, and
intellectual makeup. An experienced homeopath assesses all of these factors when determining the
most appropriate remedy for a particular individual.

     * Borax -- for nausea caused by downward motions, such as landing in an airplane

     * Cocculus -- the primary treatment for motion sickness, particularly if nausea and vertigo or other
type of dizziness are present

     * Nux vomica -- for motion sickness accompanied by headache, nausea, and ringing in the ears

     * Petroleum -- for dizziness and nausea that occur when riding in a car or boat

     * Sepia -- for motion sickness brought on by reading while in a moving vehicle

     * Tabacum -- for motion sickness with severe nausea and vomiting

There are "combination" remedies that include these remedies together. Although a classically trained
homeopath may frown upon such combinations, some find them easier and effective for home use.

Mind-Body Medicine
Biofeedback Training and Relaxation

In a study of 55 pilots who had to stop flying due to motion sickness, 76% of them overcame their
motion sickness and were able to return to work after a biofeedback training and relaxation program.
The pilots sat in a tilting, rotating chair to bring on motion sickness, while biofeedback instruments
recorded skin temperature and changes in muscle tension. While in the chair, the pilots used relaxation
techniques, such as deep muscle relaxation and mental imagery. Over time, the pilots became used to
the rotating chair and no longer felt sick as they learned to relax.

Cognitive Behavioral Therapy

Cognitive behavioral therapy is used to reduce the anxiety some people have just thinking about
movement or motion sickness. In a study of 50 pilots who occasionally had motion sickness, 86% of
them got better after cognitive behavioral therapy. During this therapy, people are slowly exposed to a
situation that causes motion sickness (such as a tilting, rotating chair) until they have some symptoms of
motion sickness, but not until the symptoms become overwhelming. As they get used to the movement,
they build confidence and their anxiety goes down.

Breathing Techniques

In a study of 46 people with motion sickness, those who took slow, deep breaths had a fewer symptoms
than those who breathed normally or counted their breaths. Rapid and shallow breathing often makes
symptoms of motion sickness worse. While it makes sense that slow, deeper breathing would help lower
anxiety, more studies are needed to see whether breathing techniques really help in reducing other

Other Considerations:

Prognosis and Complications.Although motion sickness usually goes away after the motion stops
and causes no lasting harm, it can be devastating for people whose jobs involve constant movement,
such as a flight attendant, pilot, astronaut, or ship crew member.

People who don't travel often may get used to movement during a trip lasting several days. Even those
who travel often may find that symptoms get better as they are more often exposed to motion.
However, people who get anxious before a journey often have worsened symptoms of motion sickness.
They may need help such as biofeedback and relaxation training.
