Have you ever been in a car, bus, or boat and suddenly felt dizzy, nauseous, or like you might be sick? For many, this is a very familiar and frustrating experience. Even if you are heading out for a fun trip, this discomfort can quickly ruin the entire journey. Today, we are talking about the common issue of motion sickness. While it is not a dangerous medical condition, the discomfort it causes is very real for those experiencing it.
Why does this happen to us?
Simply put, motion sickness occurs when there is a conflict between the signals your brain receives from different parts of your body. Your eyes, muscles, and specifically the inner ear provide information to the brain about your environment. When this information is conflicting, your brain becomes confused.
Imagine you are sitting in the back seat of a car looking at your phone.
- Your eyes are focused on the phone, sending a message to your brain that says, "You are sitting still."
- However, your inner ear and body clearly sense the speed of the car, the turns, and the vibrations from bumps in the road. These senses tell your brain, "No, you are moving rapidly."
Now your brain is receiving two contradictory messages. Because of this confusion, your brain reacts by making you feel dizzy, breaking out in a cold sweat, feeling nauseous, and eventually vomiting.
How are our ears and brain involved?
A primary center for controlling your body's balance is located in your inner ear. This is called the vestibular system.
This system contains fluid-filled canals and small sacs. When you move your head, this fluid shifts accordingly, sending constant feedback to your brain about your head's position. Additionally, gravity-sensitive parts tell your brain whether you are standing or lying down.
Normally, your brain collects and analyzes all this data to create a coherent picture. However, when traveling, the disconnect between what you see and what your inner ear senses makes it difficult for your brain to process the information. This confusion is what causes motion sickness.
For example, after being on a ship for several days, you might still feel like you are swaying even after you step onto solid ground. This is because of the temporary mismatch between sensory input and brain function.
Who is most affected?
Motion sickness can happen to anyone, but some people are more prone to it.
- Young children (between 2 and 12 years old)
- Pregnant women
- People who suffer from migraines
Most importantly, this is not a contagious disease; you cannot catch it from someone else.
Common symptoms
Motion sickness can start suddenly. It may begin with slight discomfort and increase in intensity over time.
| Symptom | Description |
|---|---|
| Nausea and vomiting | This is the primary and most troublesome symptom. |
| Dizziness | A feeling as if your environment is spinning. |
| Cold sweats | Suddenly feeling cold and breaking out in a sweat. |
| Increased salivation | Often occurs just before vomiting. |
| Pale skin and loss of appetite | Change in skin color and a total lack of desire to eat. |
| Other symptoms | Some may experience headaches, extreme fatigue, or shallow breathing. |
How can you reduce this discomfort?
Often, once you adjust to the travel or the journey ends, these symptoms disappear on their own. If you can't wait for that to happen, try these simple tips:
- Look ahead: Look at a stable object far in the distance, such as a tree or a hill, through the front window. On a boat, look at the horizon.
- Stay calm: Take deep breaths. Some people find closing their eyes helps.
- Avoid reading: During the journey, avoid reading books, magazines, or staring at your phone. This is a primary trigger for motion sickness.
- Allow fresh air: Open a window to let fresh air reach you. Avoid being near people who are smoking, and avoid smoking yourself.
- Food and drink: Don't travel on an empty stomach, but avoid eating heavy meals. Eat light snacks. Avoid alcohol completely.
- Choose the best seat: If possible, choose the front seat in a car, the middle of a bus, over the wing of a plane, or the center of the deck on a ship. These locations have less vibration and motion.
Natural Remedies
Some people find relief with these options:
- Ginger: Often recommended for nausea. However, ginger can thin the blood, so if you take medication for other conditions (especially heart disease or diabetes), be sure to talk to your doctor before trying this.
- Mint: Chewing mint gum or smelling peppermint can provide relief for some.
Medications and Medical Advice
If you suffer from this discomfort frequently or severely, talk to your doctor about suitable medication. While some are available over-the-counter, consulting a medical professional is safest.
- Dimenhydrinate (Dramamine) and Meclizine (Antivert, Bonine) are commonly used. These should be taken about an hour before travel.
- Scopolamine is a patch worn behind the ear. It is typically applied a few hours before travel and remains effective for up to three days.
Remember, many of these medications can cause drowsiness and dry mouth. Therefore, you should avoid driving or operating heavy machinery after taking them.
When should you see a doctor?
Usually, motion sickness fades after the journey. However, you should consult a doctor if you experience the following:
- Continued dizziness or vomiting for hours after the journey ends.
- Severe headaches.
- Chest pain.
- Hearing loss or ringing in the ears.
- Difficulty walking or persistent balance issues.
In such cases, please consult your doctor immediately to determine if these are symptoms of motion sickness or another underlying medical condition.
Key Takeaways
- Motion sickness is not a serious illness; it is a temporary condition caused by conflicting signals to your brain.
- Avoid reading or looking at screens while moving. Looking into the distance and getting fresh air can help manage symptoms.
- Children and pregnant women are more susceptible.
- Before taking any medication, especially if you have other health conditions, always consult your doctor.
- If symptoms are severe or persist long after travel, seek medical advice.
