Crying, not at all new for us. Science says crying is not only an entirely emotional behavior, but it’s actually an evolutionary survival tactic. To explain more, there are three types of tears - basal, reflex and psychic. The act of crying is also known as lacrimation. Crying can also be described as a hormonal reaction to dispose of the excess stress on the brain. They can also be described as non-verbal communication in response to pain emotional or physical. It is also taken as a result of a sudden outburst of emotions-agony, joy, surprise or pain.
This is what happens to your body when you cry.
The endocrine system is responsible for releasing hormones that control the functioning of the body. In the case of tears, if a person has a sudden outburst of emotions, the endocrine triggers the ocular area of the eyes to release tears.
Just as your hormones are triggered and you feel that you are lost in grief or in surprise, the truth is that the endocrine has released a special hormone called cortisol which makes you hyper aware of every action and reaction happening around.
The hyper aware hormone cortisol creates pressure on the throat, also known as a global sensation. It feels as if an elephant is sitting on your chest and at that time tears feel like the only resolve.
With tears, we detox stress immediately, release endorphins that calm our mood and after crying, one feels a lot lighter.
Just as you have shed your tears, you convey to the world your emotions. The non-verbal form of communication helps convey your sudden outburst as a justified and sometimes embarrassing display of inner feelings. To complete the two-way communication, the receiving human or audience consoles or congratulates you.
Researchers over the years have been battling the question if humans are the only beings on earth capable of expressing their emotion through tears. Various studies have been conducted by evolutionary theorists to highlight if the pain signaling reaction is only limited to homo sapiens or is also a feature in others. The questions are many but for now we just have to be thankful for the awesome biochemical process that helps us feel free.
