eli5 why do we tear up when we feel sad?
In: 9
When we feel sad, our body produces chemicals called hormones that can cause physical changes in our bodies. One of these changes is the production of tears. Tears are produced by the lacrimal glands, which are located above the outer corner of each eye. When these glands produce too many tears, they can overflow and spill out of our eyes, causing us to cry.
Tearing up when feeling sad is a normal physiological response that occurs in many people. When we feel emotional, our body produces hormones, such as adrenaline and cortisol, which can cause physical changes, such as increased heart rate, sweating, and increased tear production. Tears are produced by the lacrimal glands in the eyes, and they serve a number of important functions, including lubricating the eyes and removing debris. When we are feeling emotional, such as when we are sad, our lacrimal glands may produce more tears than usual, leading to the sensation of tearing up. This response is thought to be an evolutionary adaptation that helps to protect the eyes and keep them healthy.
As in what is the purpose? You signal to other humans that you are in distress and might need help. A lot of human traits revolve around social communication.
