Motion Sickness (Travel Sickness): Symptoms, Causes, Types & Treatment

Motion sickness is the feeling that develops when the motion you sense with your inner ear is different from the motion you visualise. Most of us have experienced this distasteful sensation while travelling in an aeroplane, automobile, or amusement park ride. It develops in the event of a conflict between the vestibular, visual, and other proprioceptive systems and is the common response to motion stimuli during travel [1] .

You will feel nauseous and may vomit, as well as develop a severe headache. In comparison to adults, children between the ages of 3 and 12 are increasingly susceptible to motion sickness. Women experience motion sickness more than men and are increasingly viewed during menstrual cycles and pregnancy [2] .

The dizziness, light-headedness, or nausea caused by motion sickness is a result of your body's sensory organs' mixed signals to the brain. Your inner ear helps in controlling the sense of balance (a part of the vestibular system which contains three pairs of semicircular canals and two sacs, called the saccule and the utricle) and send information to the brain whether you are lying down or standing up [3] , [4] .

When you are moving in an aeroplane, you will know the feeling. However, your eyes will not be able to distinguish it - causing your brain to get mixed signals that can be confusing. It is the same when it comes to sailing in a ship or a boat (sea sickness). This, in turn, results in the development of nausea and headache [5] .

Types Of Motion Sickness

Travel sickness is categorised into three and they are as follows [6]

1. Motion is felt but not seen

In this, the motion is felt by one's vestibular system but no motion or little motion is detected by the visual system. This is termed as terrestrial motion sickness. Carsickness, airsickness, seasickness, centrifuge motion sickness, virtual reality disorientation, and dizziness due to spinning all fall under this category.

2. Motion is seen but not felt

In this case, the motion is sensed by the visual system, so the motion is seen, but no motion or little motion is sensed by the vestibular system. It is referred to as visually induced motion sickness. Space motion sickness, disorientation from films, video games, and other screen images, and virtual reality disorientation fall under this category.

3. Motion that is seen and felt, but visual and bodily perceptions are different

In this, the sense of motion in the vestibular system does not match with the motion that is seen. This happens in an environment where gravity is simulated [7] .

Symptoms Of Motion Sickness

The severe signs of the condition are as follows [8]

  • nausea
  • vomiting
  • pallor
  • pale skin
  • sweating
  • drooling
  • loss of appetite
  • short breath
  • dizziness
  • drowsiness

Mild symptoms of the condition are as follows [9]

  • headache
  • mild unease
  • yawning

Some of the other common symptoms include sweating, malaise and a general feeling of discomfort [10] .

Causes Of Motion Sickness

Travel sickness develops when there is a conflict between one's senses. When the central nervous system receives conflicting messages from the sensory systems, that is, the inner ear, eyes, skin pressure receptors, and the muscle and joint sensory receptors - one gets motion sickness [11] . The brain will not be able to understand all the mixed signals, thereby causing the symptoms such as nausea and dizziness [12] .

Diagnosis Of Motion Sickness

As the condition does not have any complications, it usually resolves quickly without the need for professional diagnosis. It can be easily diagnosed by observing the signs and symptoms that occur when you are moving or travelling [13] .

Treatment For Motion Sickness

Various medications are available for treating the signs and symptoms. The medicines can be taken prior to travel so that it will help in preventing motion sickness [14] .

Medications

  • Promethazine: It has to be taken 2 hours before travelling and the effect lasts for 6-8 hours. It may cause drowsiness and dry mouth [15] .
  • Scopolamine: It is the most commonly prescribed medication for motion sickness. You need to consume this one before the symptoms come to the surface. You can get it in the form of a patch, and place it behind the ear 6-8 hours before travel.
  • Cyclizine: It is most effective when taken at least 30 minutes before travel and is not recommended for children younger than 6.
  • Meclizine: It is most effective when taken 1 hour before travel and is not recommended for children under 12.
  • Dimenhydrinate chewing gum: This allows the absorption of the medication through the cheek [16] .
  • Dimenhydrinate: It has to be taken every 4-8 hours.

Tips To Ease Motion Sickness

Most people are not really affected by the symptoms of the condition when they tend to get used to the situation or the movements. You can adopt the following steps to ease the discomfort caused by the symptoms [17] .

  • Focus on a stable object. For example, if you are in a car, look through the windshield.
  • Relax and focus on things like taking deep breaths or counting backwards from 100.
  • Close your eyes for sometime.
  • Chew on peppermint or chewing gums.

Prevention Of Motion Sickness

  • Do not smoke [18] .
  • Avoid reading.
  • Do not consume alcohol [19] .
  • Avoid dairy products, foods high in salt, protein, or calories, unpleasant odours, and large meals.
  • Do not watch or talk to another traveller who is having motion sickness, as it can cause you to develop the same.
  • Try not to sit in a seat facing backwards [20] .
  • Get plenty of rest the night before travelling.
