Motion sickness can happen from any
kind of movement, even movement that you are anticipating. People tend to get
motion sickness on a moving:
* Boat
* Train
* Airplane
* Car
* Amusement park rides
It usually stops as soon as the
motion stops.
Causes
Motion sickness happens when the
body, the inner ear, and the eyes send conflicting signals to the brain. This
most often happens when you are in a car, boat, or airplane, but it may also
happen on flight simulators or amusement park rides. From inside a ship's
cabin, your inner ear may sense rolling motions that your eyes cannot see. On
the other hand, your eyes may see movement on a "virtual reality"
ride that your body does not feel. Even viewing a 3D movie may cause symptoms
of motion sickness.
Once a person gets used to the
movement and the motion stops, symptoms may come back (although usually only
briefly). Sometimes just thinking about movement can cause anxiety and symptoms
of motion sickness. For example, a person who had motion sickness before might
get nauseous on an airplane before take off.
Remedy
Researchers believe that they could
develop a new treatment for seasickness in the next few years, thanks to a
breakthrough in the area of concern.
A group of researchers from Imperial
College London (ICL) found in a new study that after shooting a mild electrical
current to the scalp, people suffering from overstimulation of their responses
like motion sickness will lessen their inadaptive capacities. With that said,
feelings of nausea or even vomiting during a boat or a roller coaster ride will
considerably be lessened when an adequate amount of electrical current is given
beforehand.
It helps the brain in reducing the
impact of the confusing inputs that it receives. Thus is becomes able to
prevent the problem that originates motion sickness’ symptoms. According to
researchers, people who suffer seasick in a ship will be able to get an effective
cure within five to ten years.
The lead researcher, Dr. Qadeer
Arshad said that after a series of tests, their team concluded that using such
technique is safe for use. Eventually, when all the paperwork is done, the
electrical devices will then be available in drugstores. The proponents of the study also added that the
device would be very similar to that of a tens machine used to alleviate back
pain. They are also thinking of integrating the technology in mobile phones by
putting it into headphone jacks wherein the jacks will deliver small amounts of
electricity into the surface of the skin.
Before coming up with the conclusion,
they experimented on the effects of the electrical signals by attaching
electrodes on the scalp of their respondents for about ten minutes. After such,
the participants of the study were asked to ride on a motorized rotating chair,
which could induce motion sickness. After collating data, the scientists
concluded that those who received the electrical signals were less likely to
report feelings of nausea.
The researchers think that this
breakthrough technique will be the ultimate solution to motion sickness because
the tablets available to treat such can cause severe drowsiness. The goal of
the study is to give people quality experiences even in motion-packed
activities.
Findings of the study appeared in the
most recent edition of the prestigious journal Neurology.
