Is science moving closer to unravelling the belief that every wife was created from her husband’s right rib? Your husband is aggressive? Science has discovered one thing a wife can do to help. Shed tears! You actually want to read this.
A chemical signal in human female tears lowers aggression in males, scientists in the United States have found out.
Platforms Africa reports that a study conducted by six researchers at the National Institute on Drug Abuse Intramural Research Program, UNITED STATES; Shani Agron, Claire A. de March, Reut Weissgross, Eva Mishor, Lior Gorodisky, and Tali Weiss, which revealed this also proved that between a man (husband) and woman (wife) exist so much more connections, physical and spiritual, than previously known.
The study, which also highlighted the different types of tears, notes that an emotional tear, effective on man’s aggression, has no odour.

A part of the hypothetical connection expressed as a belief by adherents of Abrahamic faiths – Islam, Jew, and Christianity – is that a wife was created from the Husband’s right rib, Platforms Africa reports.
Studying the connection between a female emotional tears and aggression in male, the study edited by Thorsten Kahnt of the National Institute on Drug Abuse Intramural Research Program, which used rodents in a laboratory experiment, submitted that sniffing emotional tears with no odor percept reduced human male aggression by 43.7%.
The study reads; “Rodent tears contain social chemosignals with diverse effects, including blocking male aggression. Human tears also contain a chemosignal that lowers male testosterone, but its behavioural significance is unclear. Because reduced testosterone is associated with reduced aggression, we tested the hypothesis that human tears act like rodent tears to block male aggression.
“Using a standard behavioural paradigm, we found that sniffing emotional tears with no odour percept reduced human male aggression by 43.7%.
“To probe the peripheral brain substrates of this effect, we applied tears to 62 human olfactory receptors in vitro. We identified 4 receptors that responded in a dose-dependent manner to this stimulus.
“Finally, to probe the central brain substrates of this effect, we repeated the experiment concurrent with functional brain imaging.

“We found that sniffing tears increased functional connectivity between the neural substrates of olfaction and aggression, reducing overall levels of neural activity in the latter. Taken together, our results imply that, like in rodents, a human tear–bound chemosignal lowers male aggression, a mechanism that likely relies on the structural and functional overlap in the brain substrates of olfaction and aggression.
“We suggest that tears are a mammalian-wide mechanism that provides a chemical blanket protecting against aggression,” the study obtained by Platforms Africa showed.
