Kinetosis: what é, symptoms, causes and treatment

The motion sickness, popularly known as "motion sickness", is characterized by the appearance of symptoms such as nausea, vomiting, vertigo, cold sweats and malaise, when traveling by car, plane, boat, bus or train, for example.

Generally, the symptoms of motion sickness can be prevented with simple measures, such as sitting in the front of the vehicle and avoiding alcoholic drinks or heavy foods before a trip, but in some cases, the doctor may also prescribe taking antiemetic medication to help relieve discomfort.

What causes motion sickness

Still motion sickness happens when the signals that the brain receives through the eyes are different from the movement felt by the body.For example, when traveling by boat, especially at sea, it is possible for the body to feel that it is rising and falling in the swell, but the eyes may not see this change, which causes the brain to receive different signals, developing the sensation. of malaise and nausea.

Some people are more sensitive to this type of change and, therefore, may present symptoms of motion sickness even at other "more common" times such as traveling by car or bus, for example.

Symptoms can be even worse when doing another task on the move, such as reading or using a laptop, as the eyes are watching a fixed image, while the body continues to feel the movements of the trip.

Main symptoms

Symptoms that can occur in people with motion sickness are:

  • Sickness;
  • Vomiting;
  • Dizziness;
  • Cold sweats;
  • General malaise.

Also, some people may also have difficulty maintaining balance.

These symptoms are especially common in children aged between 2 and 12 years and in pregnant women.

How the treatment is done

To avoid and relieve motion sickness caused by motion sickness, it is important to adopt some measures such as:

  • Sit in the front seat or by a window and look at the horizon;
  • Avoid reading while traveling or using devices such as cell phones, laptops or tablets;
  • Avoid smoking and drinking alcohol before and during travel;
  • Have a light and he althy meal before the trip, avoiding very acidic or fatty foods;
  • Open the window slightly to get fresh air whenever possible;

In addition, if the symptoms persist or if they are very intense, the doctor may also prescribe the use of medicines that prevent symptoms, such as dimenhydrinate (Dramin) or meclizine (Meclin), which should be taken about half an hour to an hour before travelling. Learn more about Dramamin.

These drugs act on the vestibular and reticular systems, responsible for nausea and vomiting, and also act on the vomiting center, preventing and treating the symptoms of motion sickness. However, they can cause side effects, such as drowsiness and sedation and, therefore, should always be indicated by a doctor.
