There's more to your tears than what meets the eye...(see what we did there?)
Crying is one of the most basic responses to our emotions - from sadness to frustration and many other complex things. Humans tend to tear up from time to time for a lot of reasons.
Some of the deepest emotions produce tears, and that is what we tend to associate crying to. But there's more to crying - it is good for your health.
Here's how crying is good in ways people generally don't know:
In recent studies, researchers have found that human tears have a lot of toxins; and the hormones that our bodies produce when we are stressed. Researchers believe that if crying flushes out these stress hormones, it can lead to reduced levels of overall stress.
Though this field still needs more research.
Tears are by default antibacterial. Human Tears also contain a chemical known as lysozyme - which kills germs and keeps the eyes clean. Lysozyme's protective power was seen in a study in 2011, where researches said it could reduce effects of bioterror agents, such as anthrax.
Studies have found that crying also releases oxytocin and endorphins. Emotional tears tend to prompt our brain to release these hormones which can ease both physical and emotional pain. This way, research says that crying can help you heal and feel a sense of well-being.
Self-soothing is a person's ablity to control their own emotions - and also feel those emotions properly at the same time.
A study in 2014 found that crying might have a direct corealtion with self-soothing. Researchers say that crying activates parasympathetic nervous system, which helps people relax.
As crying produces more tears, Basal tears also tend to get produced more. Basal tears are released when a person blinks. They help to keep the eyes moist and prevent mucous membranes from drying out.
As the National Eye Institute explains, the lubricating effect of basal tears helps people to see more clearly. When the membranes dry out, vision can become blurry.
So whenever you are feeling emotional, do not worry, your eyes are getting cleaned and you are getting better.
