Hi there! Have you ever wondered why people cry? It’s a fascinating question, and today we’re going to explore the reasons behind it. Crying is something everyone experiences, and it can happen for many different reasons. Let’s dive into the science of crying and discover why it happens.
Crying might seem like a simple reflex, but it’s actually controlled by a part of our brain. The amygdala, which processes our emotions, sends signals to another part of the brain called the hypothalamus. This triggers the sympathetic nervous system, which is also responsible for the fight-or-flight response. That’s why when we cry, we might also notice our heart beating faster.
Another key player in crying is the lacrimal gland, located between your eyelid and eyeball. When something emotional happens, your brain tells the lacrimal gland to produce tears. These tears can either roll down your cheeks or drain through tiny openings called the lacrimal punctum.
Crying is a human response that has evolved over time, and it might have some benefits. For instance, emotional tears contain a natural painkiller called leucine enkephalin. This could be why crying often makes us feel better afterward. However, it’s probably best not to taste someone else’s tears!
Some experts think that crying evolved as a way to show others that something is wrong. When someone cries, people around them often feel sympathetic and want to help. This would have been especially useful before humans developed language, as crying could signal that someone needed assistance.
Studies have shown that women tend to cry more than men. For example, research from the 1980s found that men cried about 1.3 times a month, while women cried about 5.3 times. This includes all kinds of crying, even just having watery eyes.
There are a few reasons why men might cry less than women. Some of it might be biological, as hormones like testosterone could make men less likely to cry. Cultural factors also play a role. In societies where showing emotions is discouraged, both men and women tend to cry less.
Crying is a complex and fascinating human behavior. It involves our brain, emotions, and even social interactions. Whether we’re shedding tears of joy or sadness, crying is a natural part of being human. So, the next time you find yourself crying, remember that it’s a normal and healthy way to express your feelings!
Thanks for exploring this big question with us! If you have any other questions you’re curious about, feel free to ask. See you next time!
Using what you’ve learned about the science behind crying, create a flowchart that shows the process from emotional trigger to tear production. Include the roles of the amygdala, hypothalamus, sympathetic nervous system, and lacrimal gland. This will help you visualize and understand the steps involved in crying.
In small groups, come up with different scenarios that might cause someone to cry, such as receiving good news or experiencing a loss. Act out these scenarios and discuss how each situation might trigger the crying process. This activity will help you explore the emotional aspects of crying.
Choose a culture different from your own and research how crying is perceived and expressed in that culture. Present your findings to the class, highlighting any differences or similarities you discover. This will give you a broader understanding of how cultural factors influence crying.
Conduct a simple experiment to learn about the composition of tears. Collect tears (safely and hygienically) and observe them under a microscope if possible. Research what substances are found in emotional tears compared to reflex tears. This will help you understand the biological aspect of crying.
Think about a time when you cried and write a journal entry about the experience. Reflect on what triggered the crying, how you felt afterward, and any social interactions that occurred. This personal reflection will help you connect the scientific concepts to your own experiences.

Hi, I’m Craig, and this is Mental Floss on YouTube. Today, I’m going to answer Brianna Stanhope’s big question: Why do people cry? Well, Brianna, you’re in luck because crying is something I know well.
This is a complicated question because people cry for many reasons. For example, babies cry because they need to communicate, while adults might cry when they’re happy, sad, or even when they have something in their eye. For this episode, let’s focus on why people cry when they’re emotional.
First, let’s discuss the physical act of crying. Although it may seem like a reflex, there’s a part of the brain that controls it. The amygdala processes emotions and sends signals to the hypothalamus, which alerts the sympathetic nervous system. This is the same system that is connected to the fight-or-flight response, which is why other functions occur when we cry, such as an increased heart rate.
Another important component is the lacrimal gland, located between the eyelid and the eyeball. When something emotional happens, the brain sends a signal to the lacrimal gland, which produces tears. These tears can either run down your cheek or be drained through the lacrimal punctum.
Crying is a human response that has evolved over time, likely providing some benefits. Experts have identified a few, such as the fact that emotional tears contain leucine enkephalin, a natural painkiller. This may explain why crying can make us feel better, which many people have experienced after a good cry. However, it’s best to refrain from licking others’ tears!
Some experts believe that crying evolved as a social cue to indicate that something is wrong. People tend to feel sympathetic toward someone who is crying, which can have social benefits. This would have been particularly useful before humans developed language, as crying signaled that someone was hurt or needed help.
Experts also consider gender differences when discussing why people cry. Studies from the past few decades indicate that women cry more than men. One study from the 1980s found that, on average, men cried about 1.3 times a month, while women cried about 5.3 times. This includes all types of crying, even just having watery eyes.
There are several reasons why men might cry less than women. Some of this may be biological, as testosterone could play a role in making men less likely to cry. Additionally, environmental factors can influence crying behavior. In cultures where emotional expression is discouraged, men and women tend to cry similar amounts.

Crying – The act of shedding tears, often as a response to emotions such as sadness or happiness. – When Sarah watched the sad movie, she couldn’t help crying because the story was so touching.
Emotions – Feelings that are experienced in response to thoughts, events, or memories, such as happiness, anger, or fear. – During the roller coaster ride, Jake felt a mix of emotions, including excitement and fear.
Brain – The organ in the head that controls thoughts, memory, emotions, and the body’s activities. – The brain is responsible for processing all the information we receive from our senses.
Amygdala – A part of the brain involved in processing emotions like fear and pleasure. – The amygdala helps us react quickly to dangerous situations by triggering a fear response.
Hypothalamus – A small region of the brain that controls many bodily functions, including hunger, thirst, and temperature regulation. – The hypothalamus plays a crucial role in maintaining the body’s internal balance, known as homeostasis.
Tears – The liquid that comes from the eyes when a person cries, which can be due to emotions or irritation. – Tears rolled down her cheeks as she laughed uncontrollably at the funny joke.
Sympathetic – Relating to the part of the nervous system that prepares the body for action and stress. – The sympathetic nervous system increases heart rate and energy levels when you’re scared or excited.
Biological – Relating to living organisms and their vital processes. – Biological studies help us understand how different species adapt to their environments.
Hormones – Chemical substances produced in the body that regulate various physiological processes and behaviors. – During puberty, hormones cause many changes in a teenager’s body and emotions.
