How to feel less nauseous. Will brain ‘zapping’ work?


How to feel less nauseous.

As part of the quest to find out how to feel less nauseous when travelling, the use of electric shock therapy is being trialled at the Imperial College London. Scientists believe that electricity will stimulate areas of the brain which will reduce the symptoms of motion sickness.

A selection of 20 volunteers were subjected to an experience in the ‘Chunder chair’ which spins the person around at an angle to induce motion sickness. 1 hour later half of the participants had small electrical currents passed through the scalp to change the brain activity. The other half were subjected to dummy treatment. For those who had the stimulation it took an extra 200 seconds for the motion sickness to develop. Those receiving the dummy treatment experienced motion sickness problems around 60 seconds earlier.


It would be irresponsible to conclude that this study provides anything more than very early evidence of a potential benefit.

Prof Chris Chambers is the head of brain stimulation at Cardiff University, he has commented: “It would be irresponsible to conclude that this study provides anything more than very early evidence of a potential benefit. Until the findings are replicated in a large registered trial, I recommend that the public approach any claims about treatment benefits with a healthy scepticism.”

Those of us who suffer from travel sickness must surely wonder why the delay of 1 hour before administering motion sickness treatment of any kind as, for us, motion sickness problems would take effect immediately the chair started rolling around.

It surely must be questioned, why is it necessary to introduce electric shock treatment at all when there so many effective cures available over the counter?

Overload causes nausea.

The limited research into motion sickness that we have done clearly indicates that over-loading the brain with too much confusing information is what causes nausea. The solution to this problem is to reduce as much of this information as we can to a level where the brain can cope. One significant area where this can be reduced is visual information which we don’t need to see. If we can block out the fast moving scenery, as the Gamlin Travel Visor does, then this would be a good start down the road of managing nausea causes and cut out the need for any sort of motion sickness medication.
