Several previous studies proved that the compound molecules in tears varies trigger. Emotional tears when sadly different dripping with tears when exposed to steam onions or irritation by dust.
Emotional tears dripping on women as sad and cry a hormonal influence on the men who breathe it. Production decreased male hormone testosterone, which in turn can reduce aggression and sexual arousal.
This fact was revealed in a study carried out an expert team at the Weizmann Institute of Science. In that study, a team led by Prof. Noam Sobel participants included 24 adult males with an age range that are not mentioned in more detail.
Each was given 2 types of liquid to be inhaled, ie, emotional tears of a woman and a solution of common minerals that are equally odorless. After inhaling a liquid whose composition is kept secret of the participants exhibited some random woman’s facial image, and then asked to give an assessment.
Analysis of assessment results show, 17 participants felt the distinct impression after inhaling the two types of liquids. The pictures that appear less stimulating after participants sipped liquid containing tear, compared to normal after inhaling mineral solution.
Apart from the results of an assessment of the picture, the participants’ brain scans with magnetic resonance imaging (MRI) provides the same conclusion. Activity in the brain that usually increases during sexual arousal appears to decrease after inhaling tear.
“The fact that the composition of different tear is an indication that the tear is a chemical signal for humans to communicate. This study further reinforces these allegations,” said Prof. Sobel.
For a while this effect was discovered in the tears of women, especially the drips due to emotional factors and not because of irritation. In subsequent research later, Prof. Sobel wanted to observe whether the same effect also occurs in tears of men and children.
