Why does tears come out when we cry? This question has intrigued scientists and philosophers for centuries. Tears are a complex and multifaceted aspect of human emotion, and their presence during crying serves various purposes that go beyond mere cleansing of the eyes.
Tears are produced by the lacrimal glands, which are located above the outer corners of the eyes. When we cry, these glands secrete tears onto the surface of the eyes, and they flow down the cheeks. There are three main types of tears: basal tears, reflex tears, and emotional tears.
Basal tears are produced continuously to keep the eyes moist and healthy. They provide a protective layer that prevents the eyes from drying out and helps to maintain clear vision. Reflex tears are produced in response to irritants, such as dust, smoke, or wind, and they help to wash away these irritants and protect the eyes from damage.
However, emotional tears are the most fascinating type of tears. They are produced when we experience strong emotions, such as sadness, joy, or anger. Emotional tears contain higher levels of stress hormones, such as adrenocorticotropic hormone (ACTH) and leucine enkephalin, which are associated with pain and stress. This suggests that emotional tears may have a role in the body’s stress response.
One of the primary reasons why tears come out when we cry is to help us cope with emotional pain. Crying is a natural mechanism for releasing emotional tension and stress. When we cry, the tears carry away the stress hormones, which can help us feel better. Additionally, crying can serve as a social signal, allowing us to express our emotions to others and seek comfort and support.
Moreover, emotional tears can have a therapeutic effect. Studies have shown that crying can reduce the levels of stress hormones in the body and increase the levels of endorphins, which are natural painkillers and mood elevators. This can lead to a sense of relief and well-being after a good cry.
In conclusion, tears come out when we cry for several reasons. They help to keep our eyes healthy, protect them from irritants, and serve as a natural coping mechanism for emotional pain. Emotional tears, in particular, can have a therapeutic effect by reducing stress and improving mood. So, the next time you find yourself shedding tears, remember that it’s a natural and beneficial response to the complexities of human emotion.
