Why When We Cry Tears Come Out: The Science Behind Emotional Tears
Crying is a universal human experience, a complex emotional response that can occur in a variety of situations. One of the most intriguing aspects of crying is the physical manifestation of tears. Why when we cry do tears come out? This article delves into the science behind emotional tears and explores the reasons behind this physiological phenomenon.
The Role of Tears in Crying
Tears are produced by the lacrimal glands, which are located above the outer corner of each eye. These glands secrete tears continuously, which help to keep the eyes moist and protected. When we cry, the lacrimal glands produce tears at a higher rate, leading to the visible flow of tears from our eyes.
Emotional Tears and Their Functions
Emotional tears, also known as “happy tears” or “sad tears,” are tears that are produced in response to emotional stimuli. These tears have been found to have several functions:
1. Regulation of Emotions: Emotional tears can help regulate emotions by providing a release for the stress and tension that builds up during times of distress. This can lead to a sense of relief and emotional balance.
2. Stress Reduction: Studies have shown that emotional tears can reduce stress levels. The act of crying can lower the levels of stress hormones, such as cortisol, in the body.
3. Social Bonding: Crying can also serve as a means of social bonding. When we cry, others often respond with empathy and support, which can strengthen relationships.
The Science Behind Emotional Tears
The exact science behind why emotional tears come out when we cry is not fully understood, but several theories exist:
1. Neurotransmitter Release: Emotional tears may be a result of the release of neurotransmitters, such as serotonin and norepinephrine, which are associated with mood regulation. The release of these neurotransmitters can trigger the lacrimal glands to produce tears.
2. Hormonal Changes: Emotional tears may also be influenced by hormonal changes. For example, the hormone prolactin, which is associated with the production of milk during breastfeeding, has been found to increase during crying, potentially leading to the production of emotional tears.
3. Neural Pathways: Emotional tears may be the result of neural pathways that connect the brain’s emotional centers with the lacrimal glands. When we experience strong emotions, these pathways may become activated, leading to the production of tears.
Conclusion
In conclusion, why when we cry tears come out is a question that touches on the intricate relationship between our emotions and our physical responses. Emotional tears serve several important functions, including the regulation of emotions, stress reduction, and social bonding. While the exact science behind emotional tears is still being explored, it is clear that crying is a complex and fascinating aspect of human experience.
