What Is Motion Sickness?
Motion sickness is an unpleasant combination of symptoms like dizziness, nausea, and vomiting that can happen from any kind of movement. It has been estimated that one in three people may get motion sickness at some point. This condition is commonly seen in women and children aged 2 to 12. But still, the condition can affect anyone.
What Are the Causes of Motion Sickness?
Motion sickness or kinetosis occurs when two motion messages to the brain conflict. One motion message is from the inner ear (controls balance), and another is from the eyes; due to a change in position caused by travel, these two motion messages conflict, causing motion sickness.
Sensory organs play a major role in the mechanism of motion sickness. The sensory organs will inform the brain in what direction the body is pointing, moving, and whether standing still or turning. These messages will be then passed on to the inner ears, eyes, the skin pressure receptors in the feet, muscle, and joint sensory receptors, which track what body parts are moving, and the central nervous system that includes the brain and spinal cord for processing all incoming sensory information.
They are also named car sickness, airsickness, or seasickness. People with a history of motion sickness should ask a healthcare provider how to prevent another episode from occurring in the future.
There is a disagreement between the brain's signals from ears, eyes, and other sensory receptors.

Sit where there is fresh air while traveling.
-
Take medication for motion sickness at least 30 to 60 minutes before traveling.
-
Do not travel during difficult weather conditions like storms, large waves, air turbulence.
-
Avoid traveling in rough terrain, where frequent acceleration and deceleration will occur.
-
Avoid traveling where visibility is reduced.
-
Avoid watching or talking with a co-traveler who is having motion sickness.

The head can rest on the back of the seat.
What Is the Favorable Position With Least Motion?
-
Plane: Over the wing.

Boat: The level closest to the water surface with a face towards the waves and away from the rocking bow.
-
Bus: Sit near the front at the lowest level facing forward.
-
Train: Sit at the lowest level facing forward.
How to Treat Motion Sickness?
The symptoms of motion sickness will stop once the motion stops. But medication can help manage the condition during travel.
An antiemetic is a group of drugs that help control motion sickness symptoms. Over-the-counter medicines, Meclizine, can be very effective. Medications such as Meclizine (Antivert, Bonine, Meni-D, Antrizine, Phenergan, Phenadoz, Promethegan), Promethazine, Scopolamine (transdermal patches, Transderm-Scop), Dimenhydrinate (Dramamine), Diphenhydramine (Benadryl), and Cyclizine (Marezine) can be very helpful.
Before taking the medications for motion sickness, read the precautions on the package because most of these drugs may have side effects like drowsiness, dry mouth, blurry vision, or disorientation. These medications should not be taken by people who drive vehicles or operate heavy equipment.
What Are the Home Remedies for Motion Sickness?
Treatment for motion sickness usually consists of simple changes in the environment, which includes:

Getting fresh air.

Biofeedback training.

Relaxation techniques.
-
Herbs like ginger, peppermint, and tea.

Complications with motion sickness are not usually seen, but it may cause dehydration, electrolyte problems, or a lower esophageal tear due to severe or continuous vomiting when left untreated.
Conclusion:
Motion sickness is the unpleasant sensation that causes nausea and dizziness while riding in a moving vehicle. Nearly all people are affected with motion sickness, and most people will experience motion sickness at least once in their lifetime. Astronauts in zero-gravity space also suffer from motion sickness called the space adaptation syndrome. This condition cannot be cured but can be avoided and managed.
