Why do we cry

You ever wondered what happens in our bodies when we are about to cry; and why is it that we cry. I like to think about things and try to see if I can figure them out I find this to be pretty cool. Not all the time do I figure things out.

So lets get right into this, there are many reasons why we cry. Tears aren’t always a bad thing. Believe it or not tears actually help our eyes, they are a way to keep our eyes nice and healthy. According to livescience.com┬áthere are even different kinds of tears. There are tears called basal tears that help clean and lubricate the eyes.

There is another type of tears called reflex tears that happen without us even knowing. Their job is to help clear the eyes from irritations from dust or the gas that comes from cutting onions. There are also emotional tears called the psychic tears that can be used as nonverbal communication.

Overall there is a lot going on in the eye when we cry. The tears in our eyes actually help our eyes and keep them healthy.

    Wow, I actually never knew that there were differing tears. I always assumed that tears would be composed of the same solitary fluid. I also found it very interesting that there is a wider variety of substances in tears when they are brought about emotionally opposed to from pain. I subscribe to the theory that humans evolved to cry in order to elicit empathetic responses from others. Another interesting aspect of crying is its relation to babies, whom exhibit three forms of crying in order to satisfy needs and desires.

    I never knew the different tears we had were actually different TYPES of tears altogether (different “tiers” of tears, if you will). It makes sense, though, that the tears we feel when the wind is blowing in our eyes is different from the tears we feel as an emotional response to something. Dry eyes are never fun, so it’s also good that we have a function that counters them naturally.

    I definitely learned about this in my Anatomy & physiology course freshman year, it was boring back then so i didn’t retain it. Until i read this post, I was actually intrigued by your photo choice, very vibrant. Now although i knew why we cry, I never knew there were different types of tears. Very interesting, did you know tear fluid contains water, mucin, lipids, lysozyme, lactoferrin, lipocalin, lacritin, immunoglobulins, glucose, urea, sodium, and potassium?

    This was very interesting. I’ve experienced tears of joy and from sadness. I’ve also experienced tears as a natural reaction to pain and other times for no reason at all. I never knew that all these different tears had a different name. It’s also interesting to hear that tears are a form of non-verbal communication. I had never thought of it that way. Thanks for sharing.
