We are the only creatures who shed tears of anger, sadness, pain or joy. What is in the liquid?
It just happens that we cry and occasionally shed a tear, usually without being able to control when it happens. One thing is clear: when tears fall from our eyes, it (usually) has something to do with strong emotions.
1. Tears are not all the same
Our body produces three types of tears: Basal tears lubricate our eyes 24/7. Reflex tears protect our eyes from external stimuli and roll down when we chop onions or when it’s too windy. We cry emotional tears when we are sad, angry, or happy. These tears contain more protein, which makes them thicker and falls more slowly. Heather Christle, author of the book “Crying”, suspects that there is a social signal behind it: “The longer a tear takes to run down a cheek, the greater the probability that someone will notice it and its message will be perceived”.
We feel better after crying. This could be because emotional tears contain a large amount of what is called adenocorticotropin (ACTH). A German biochemist reportedly showed in 1981 that we cry the chemical that causes stress with our tears. This theory is now controversial because, according to researchers, the amount of ACTH is too low. But other studies have shown that tears are a relief when they see someone we like or who is close to us. Even better if that person also gives us comfort.

3. Tears resolve conflicts
Anyone who starts crying can end an argument in the blink of an eye. “Tears evoke compassion and guilt. This mechanism can save relationships,” explains Jesse Bering of the University of Belfast on “Huffpost.com.” Punishing someone or arguing with someone who is crying will be hard on us. “Tears are like a trigger that symbolizes: Now we have to withdraw.”
4. Tears are unattractive
Supposedly, tears are a real lust killer. No, not because of the distorted face and red eyes. In 2011, researchers in Israel found that men who smelled women’s tears rated their counterparts as less attractive. Not only that, the smell of tears even reduced sexual arousal: The male participants’ testosterone levels dropped when they smelled the women’s tears.
5. Tears run down the nose
As soon as the tears roll down, it doesn’t take long for the runny nose to appear. This is because the eyes and nose are connected by the tear duct. When we cry, our tear ducts produce more fluid than usual. A part is excreted through the eye, the rest runs through the tear duct through the nose. smell!
do you cry often? Or do you find it quite difficult to allow emotions?
