It helps. Many people get seasick, but the exact mechanism of motion sickness has not yet been figured out. Read about different ways to cope with motion sickness. in my article yesterday. There are persuasions and persuasions in the list of useful activities.
Motion sickness occurs somewhere in the head, and therefore, if you convince a person that he will not vomit, then he is usually less sick. The method of persuasion does not matter.
One of the methods includes gluing the navel crosswise with an adhesive plaster. This thing doesn't affect nerves or reflexes in any way, but it distracts attention from nausea and reminds of the promises the victim received.
In the overseas version, not just gluing the navel, but gluing an aspirin tablet to the navel is also involved. This, of course, is already stupidity, because aspirin can cause dermatitis or allergies. Better to just cover the navel with a plaster.
From experience I know that when people, even for a serious reason, prescribe gluing something with a plaster, then many are enraged. That is, they pay attention to the patch too often. In the case of motion sickness, this is exactly what is needed. With each inhalation and exhalation, the patch pulls on the skin and clings to the shirt. The victim is distracted by this case, and he is less sick.
There is an opinion that those bracelets for motion sickness if in some cases help, which is probably for the same reason.
Immediately I thought that chewing a match or sucking candy is also from this opera.
