Why do we weep, different kinds of tears, and other interesting information regarding the salty water in your eyes
Some things can make you cry, whether it’s watching a depressing movie, hearing about a recent death, or chopping onions. According to the American Academy of Ophthalmology. Your eyes produce between 15 and 30 gallons of tears annually for a variety of objectives.
Although other animals cry, scientists have long believed that only humans are able to cry out emotionally. However, a recent Japanese study discovered that when dogs were reunited with their owners. Their eyes began to brim up with tears of joy.

How do tears form?
According to Silverstone, the lacrimal glands above your eyes are responsible for producing the water in your tears. This mixture of salt and water keeps the surface of your eyes moisturized and in good condition. Your meibomian glands. Which are located where your eyelashes are on the edge of your eyelids, are where the mucus and oil originate from. He continues, “You need both parts for your tears to function effectively. These molecules combine as you blink and spread throughout the corneal surface. They then pass through your nose and into your tear duct. Which are the tiny pores in the inner corners of your eyelids, where they either evaporate or are reabsorbed.
What distinguishes the three types of tears?
The three different kinds of tears also differ significantly from one another. Look at this more closely.
Base rips
Your eyes have been drenched with these tears all day. Your eyesight and focus are improved when you blink because you disseminate them equally throughout the surface of your eye. In order to keep your eyes healthy and free of infection, they sweep away dirt and germs.
Reflexive tears
When you slice an onion, these are the tears that come out of your eyes. Injurious irritants like smoke or dust are washed away. They are primarily made of water because they are produced by your lacrimal gland. They are produced in greater quantities by your eyes than basal tears and are filled with antimicrobial agents like antibodies.
Tears of emotion
These are the tears you cry when you’re having a crying fit. Prolactin, potassium, manganese, and stress hormones are among the extra proteins and hormones they carry that you won’t find in other tears. One explanation for why we weep is because doing so allows you to let stress out and relax your body. Your body does not naturally produce them, in contrast to basal tears. When you experience emotional tears, your brain’s limbic system. Which controls emotions, sends a message to the lacrimal glands in your eyes to start secreting tears. As a result? a real crying fest. They clog up your tear ducts when you produce a lot of them. As a result, they run out of your eyes and down your cheeks, occasionally even dripping into your nose.
Why do we cry feeling-based tears? It is believed that even emotional tears themselves serve an evolutionary function: They help to foster empathy.
What much of sobbing is deemed normal?
It’s common to cry for a variety of causes, including bodily emotional, physical, and physiological reactions. However, it’s possible to cry too much or too little. If either condition is not treated, it could harm your eyes. The following are a few conditions that aren’t regarded as typical.
Dry eye: what is it?
According to Silverstone, the amount of water produced by your lacrimal gland begins to decrease as you age. This could increase your risk of developing a condition called dry eye. Which can hurt your eyes and impair your eyesight. Additionally, you’re more prone to blepharitis, a disorder that irritates and swells the eyelids. According to Silverstone, your meibomian glands may get inflamed with time, causing their secretions to become clogged. I advise my patients to keep these glands healthy by placing a warm compress over their eyes for 15 to 20 seconds each day. It resembles the flossing of their eyeballs. Including artificial tears and even an omega-3 fatty acid supplement in the treatment plan may also assist with dry eye.
Dr. Roizen advises using artificial tears, which come in a variety of forms, to treat dry eyes. But if this persists, visit your doctor to get the necessary treatments for any eye disorders you may have and to address the root reasons.
excessive tears
Drains are the microscopic holes in the inner corners of your eyelids. These drains may expand and clog if you catch a cold. Your eyes start to tear up and fall on your face as a result. Your tear glands occasionally don’t create enough oil for the base tear mixture. An continuing tear leak can result from this as well.
irrational crying and laughing
Alzheimer’s disease, stroke, and other brain disorders are the main causes of this neurological ailment, which causes involuntary tears to flow on the surface of your eyes. Dr. Roizen says that if this occurs. you should be sure to see a doctor and describe your symptoms in full so that you can get the right care.
When to get assistance
There is absolutely no reason for you to ever hold back your emotions since, as Dr. Roizen reminds us, “all tears are there for the greater good.”
However, you should see your doctor to find out the underlying cause if your eyes are irritating, itchy, red, or swollen, or if you cry incessantly for no apparent reason in case you have an untreated illness such an eye infection.
