A recent study from the Weizmann Institute of Science found that the smell of women's tears can calm down men and reduce their aggression.
Scientists discovered a special chemical in tears that sends a calming message to men's brains, making them less likely to act aggressively.
To test their idea, researchers had 31 men play a frustrating computer game. Before playing, they smelled either a salty solution or women's tears (disguised as droplets on swabs under their noses).
The results were surprising – the men who smelled tears showed a big decrease (43.7%) in aggressive behaviour, especially in how they reacted to unfair situations in the game.
Brain scans also confirmed these changes, showing that the areas in the brain linked to aggression were less active in the men who smelled tears.
Professor Noam Sobel, the lead researcher, said that whatever is in tears seems to lower aggression. Previous research by Sobel also found that women's tears can reduce male hormones and sexual desire.
Sobel thinks that these tear-related signals may have evolved to protect babies who can't communicate when they feel threatened.
Even though using tears to influence emotions in adults might have some limitations, Sobel suggests that this biological tool could have developed to ensure the safety of helpless infants.
This study adds a new layer to our understanding of human emotions.
It suggests that crying, often seen as a sign of weakness, might actually be a powerful tool for calming conflicts and protecting people during vulnerable times.
The researchers are even hopeful about discovering similar calming signals in the tears of men and children in the future.
