WHAT IS MOTION SICKNESS?

Motion sickness occurs when a disagreement exists between your visually perceived movement and your vestibular system’s (inner ears) sense of movement. For example, when you are travelling in a moving vehicle and at the same time concentrating on a still object such as a book, your brain will be confused by the messages of movement coming from your inner ear and the conflicting messages of being still coming from the optic nerves. Anxiety from previous attacks, a full stomach and a stuffy atmosphere can make matters worse.

WHAT ARE THE MO SICKNESS SYMPTOMS?

Nausea, vomiting and dizziness are the common symptoms of travel sickness. In some case, sweating and general feeling of discomfort may be experienced.

HOW TO PREVENT MOTION SICKNESS?

Look out of the window of the moving vehicle and concentrate on something on the horizon in the direction of travel. Sit in the front seat when travelling by car and look at the distant scenery. On a boat, go up on the deck and watch the motion of the horizon. In an airplane, sit by the window and look outside. Sitting over the wings in a plane is beneficial since the motion is minimized.

Fresh, Cool air can relieve motion sickness. Foul odors can worsen nausea.

Avoid reading or studying close objects. When travelling by car or train or coach and make regular stops if possible. Do not sit in a seat facing backward.

Avoid excessive alcoholic drinks.

Avoid eating or drinking too much before travelling.

Acupuncture bands for the wrist might be helpful. alternatively, applying pressure for about 5 minutes on a certain acupressure point on either wrist can relieve nausea.

Herbal preparations containing ginger have also been shown to reduce sickness.

Medicines for prevention and treatment are most effective when administered well before the motion activity takes place.
