Things You Didn’t Know About Tears and Crying

· January 6, 2017
Did you know that humans are the only beings whose tears correspond to different feelings? Other mammal's tears don't have emotional importance.

Crying is a physiological process for all living creatures. But it’s different when humans shed tears. We are the only ones who cry to demonstrate different emotions.

In this article, we want to share some of the curiosities of tears and crying.

Crying is good for your health

For years, tears have been considered a sign of weakness and even manipulation.

In reality, when you are sad you can express it with tears. This happens because your body releases different chemicals. These substances act as a natural calming agent. In other words, they lessen the amount of pain you feel.

When you weep, your body enters a state of calmness. This is because your body releases oxytocin after crying. This chemical acts as a natural anesthetic.

Even though it may not happen often, crying is important. It protects the mucous membranes in your eyes from getting dehydrated. This helps to keep your eyes in perfect condition.

Another important factor is their cold fighting abilities. Tears can kill some bacteria. This is thanks to a fluid called Lysozime D.

To sum this up, crying is a good exercise. It helps to keep you healthy and your body functioning properly.

Are happy and sad tears the same?


The truth is, scientists put tears in three categories:

Basic tears

These are the tears that keep your cornea permanently dry. These lubricate your eyes. They also keep your eyes clean.

Under normal circumstances, a person sheds one-fifth of a teaspoon (1.1 grams) of tears a day. Over time, this amount can increase or decrease.

Reflexive tears

These are a result of some irritation. They are caused by foreign objects or the presence of irritating substances.

Anything can cause this kind of tear. The most common causes are onions, tear gas, paint vapors, and corrosive chemicals.

The purpose of these tears is to clean foreign objects from your eyes.

Emotional tears

These are the tears that are based on feelings. The feeling can be anything: happiness, sadness, anger, fury, etc.

Crying after sex

Many people feel like crying after reaching orgasm. There isn’t a consensus in the scientific community to explain this phenomenon. But, some believe that crying after sex is directly related to the hormonal fluctuation sex causes.

Others are inclined to say it is a psychological reaction. They say it can be for many reasons, such as:

  • The sensation of reaching climax.
  • Guilt when they are cheating on someone.
  • Sadness caused by being in a bad relationship.

If you always have this reaction, maybe you should analyze your relationship. You should see if your relationship makes you happy.

If you are crying because you’re happy then all is well. But, if it is because you’re unhappy, you should take a moment to consider your relationship. Think about whether it is worth it to you to stay with this person.

Men don’t cry as much as women


Stories that say that women cry more than men have been known for ages. This includes some jokes along this line. There are even studies that show that women cry four times more often than men.

This is due to the hormone prolactin. This hormone can cause a person to cry. This hormone is mostly present in women’s blood and tears.

On the other hand, women’s tear ducts have a different structure than those of men. This makes it easier for women to cry.

Animals also cry

Animals also have the ability to cry. Normally, this is noticed due to the sounds they make. It can also be noticed by the facial expressions or behavior they show.

The expressions of animals’ feelings vary from species to species. This is because of a different development of the limbic system in each species.

In some mammals and humans, it is connected with the reward center in the brain. However, humans shed tears based on emotion.

In other words, it’s impossible for animals to shed tears that have a deeper emotional meaning. They are only a result of a functional necessity.

Tears and their interesting properties


There are various “emotional” causes: to relieve stress, to show empathy and compassion, when we feel pain, when we call for attention, and even to show happiness.

Tears have the same physiological reaction. It doesn’t matter if scientists classify them as being caused by irritation or not.

What we do know is that tears provide an important function. They protect your eyes.
