A new study by scientists confirms that the so-called "fear of smell" does exist. The researchers explained that through the special chemicals (pheromone) secreted by the body's skin, people can "infect" their fears to the people around them. In addition, this information can be passed to many people around.
A total of 49 volunteers participated in this special experiment organized by scientists from the University of Düsseldorf, Germany. During the test, Dr. Betkina and his colleagues used a small cotton swab to collect the sweat secreted by 21 volunteers one hour before the start of the test and the sweat secreted during training on the bicycle contactor.
The other 28 volunteers were asked to smell the collected sweat and determine which were collected before the test and which were collected during the training.
Although no one of the volunteers can make the right distinction, the brain scan device shows that when the volunteers smell the sweat collected before the test, the emotional and social part of their brains will be more active. Scientists believe that this reflection in the brains of volunteers shows that special chemicals secreted by people in fear and panic can infect others around them.
Many scientists believe that although odor plays a very important role in people's relationship, their research is extremely limited. Previous trials have shown that temperatures from men with stronger immunity are more likely to attract women because this temperature can make the next generation better resistant to disease. In addition, when people are looking for a spouse, they are more willing to choose those who have a different temperature than themselves, because it can avoid the situation of close relatives getting married as much as possible.
A study funded by the US Department of Defense last year also showed that odors from fear or nervousness can trigger reactions in other people's brain-related areas. The sweat used in this test was collected from the first skydiver. Analysts pointed out that the US military hopes to extract chemical substances that play a key role through such tests in order to create a climate of fear in enemy forces. Meditech Medical Network
