Motion Sickness.

What is motion sickness?

Motion sickness is a sensation of wooziness. It usually occurs when you’re traveling by car, boat, plane, or train. Your body’s sensory organs send mixed messages to your brain, causing dizziness, lightheadedness, or nausea. Some people learn early in their lives that they’re prone to the condition.

The Role of the Ears.

Your inner ears, in particular, help control your sense of balance. They are part of a network called the vestibular system.This system includes three pairs of semicircular canals and two sacs, called the saccule and the utricle. They send information about what’s going on around you to the brain.

The semicircular canals hold a fluid that moves with the turns of your head. The saccule and utricle are sensitive to gravity. They tell the brain whether you’re standing up or lying down.

The Role of the Brain.

Your brain takes in all this data, and it usually comes together and makes sense. But sometimes your brain gets confusing signals.

On a flying plane, for example, you feel like you’re moving, but your eyes tell your brain that you don’t appear to be going anywhere. The opposite is true as well. After a long sea voyage, you can stand still on dry land but still feel like you’re moving.

The result is the same: motion sickness.

What causes motion sickness?

You maintain balance with the help of signals sent by many parts of the body — for instance, your eyes and inner ears. Other sensory receptors in your legs and feet let your nervous system know what parts of your body are touching the ground.

Conflicting signals can cause motion sickness. For example, when you’re on an airplane you can’t see turbulence, but your body can feel it. The resulting confusion can cause nausea or even vomiting.

What are the symptoms of motion sickness?

Motion sickness usually causes an upset stomach. Other symptoms include a cold sweat and dizziness. A person with motion sickness may become pale or complain of a headache. It’s also common to experience the following symptoms as a result of motion sickness:

▪️ nausea.

▪️vomiting.

▪️loss of or trouble maintaining your balance.

What are the risk factors for motion sickness?

Any form of travel, on land, in the air, or on the water, can bring on the uneasy feeling of motion sickness. Sometimes, amusement rides and children’s playground equipment can induce motion sickness.

Children between the ages of 2 and 12 are most likely to suffer from motion sickness. Pregnant women also have a higher likelihood of experiencing this kind of inner ear disturbance.

How is motion sickness diagnosed?

Motion sickness resolves itself quickly and doesn’t usually require a professional diagnosis. Most people know the feeling when it’s coming on because the illness only occurs during travel or other specific activities.

How is motion sickness treated?

Several medications exist for the treatment of motion sickness. Most only prevent the onset of symptoms. Also, many induce sleepiness, so operating machinery or a vehicle isn’t permitted while taking these types of medications.

Frequently prescribed motion sickness medications include hyoscine hydrobromide, commonly known as scopolamine. An over-the-counter motion sickness medication is dimenhydrinate, often marketed as Dramamine or Gravol.

How is motion sickness prevented?

Most people who are susceptible to motion sickness are aware of the fact. If you’re prone to motion sickness, the following preventive measures may help.

▪️ Plan ahead when booking a trip. If traveling by air, ask for a window or wing seat.

▪️ On trains, boats, or buses sit toward the front and try to avoid facing backward.

▪️ On a ship, ask for a cabin at water level and close to the front or the middle of the vessel. Open a vent for a source of fresh air if possible, and avoid reading.

▪️ Sitting at the front of a car or bus, or doing the driving yourself, often helps. Many people who experience motion sickness in a vehicle find that they don’t have the symptoms when they’re driving.

▪️ It’s important to get plenty of rest the night before traveling and avoid drinking alcohol. Dehydration, headache, and anxiety all lead to poorer outcomes if you’re prone to motion sickness.

▪️ Eat well so that your stomach is settled. Stay away from greasy or acidic foods before and during your travels.

▪️ Have a home remedy on hand or try alternative therapies. Many experts say peppermint can help, as well as ginger and black horehound. Although their effectiveness hasn’t been proven by science, these options are available.

For pilots, astronauts, or others who experience motion sickness regularly or as part of their profession, cognitive therapy and biofeedback are possible solutions. Breathing exercises have also been found to help. These treatments also work for people who feel unwell when they even just think about traveling.

Tips to Ease It.

For most people, symptoms usually don’t last long. They often go away once you get used to the situation, whether it’s the rocking of a boat or the movement of a train.But there are some simple things you can do if the motion sickness isn’t going away on its own:

▪️ Relax. Find something to focus on, whether it’s taking deep breaths or counting backwards from 100. Closing your eyes can help, too.

▪️ Look at a stable object. If you’re on a boat, look at the horizon. If you’re in a car, look through the windshield.

▪️ Avoid alcohol. Eat lightly before travel but don’t fast.

▪️ Breathe fresh air — and don’t smoke.

▪️ Avoid reading.
