Tears and all of our other body fluids are salty because of electrolytes, also known as salt ions. Our bodies use electrolytes to create electricity that helps power our brains and move our muscles. Electrolytes contain: Sodium (which accounts for the saltiness)
Basal and reflex tears contain higher levels of salt than emotional tears. This helps protect your eyes and keep them healthy. What emotional tears lack in salt, they make up for in hormones. These hormones work as a natural painkiller by restoring balance in the body and reducing stress levels.
Tears are a complex mix of proteins, antibodies and other substances, and have antibacterial and antiviral properties. If you could collect enough to drink, they would be more nutritious than water. Here are eight amazing facts about one of the most important bodily functions...
Why does salt water in the ocean sting your eyes, but not your salty tears? Answer: There is a tiny amount of salt in your tears, but its minor compared to the amount of salt present in salt water. Your tears contain about 0.9% sodium chloride, while salt water in the ocean contains 3.5%!
Emotional tears are the least salty of all tear types. That's why your eyes get puffy when you cry. Water naturally moves to the saltier areas of your eye.
Emotional tears contain various ingredients & cause the tears to taste slightly different. If you are sad tears taste a bit sour because the acidity is higher, while happy tears taste slightly sweeter.
It's best not to hold in emotions all the time, but sometimes it's important to hold back tears. If you need to control a cry, try to hold back your tears just until you're in a better place for them. This way you won't suppress your emotions altogether.
“Since crying has been proven to reduce stress, crying may have a positive effect on a person's skin over time,” she explains. “Skin issues such as acne and breakouts can be caused by stress, and, therefore, crying can indirectly reduce acne breakouts by reducing the stress.”
In the short term, it can cause pesky problems such as irritability, anxiety, and poor sleep. But over time, repressing your tears can lead to cardiovascular diseases such as hypertension — or even cancer.
Trace or touch DNA can also be retrieved from used contact lenses. Since tears can be secreted due to an emotional response, they can attract forensic analysis for identification. DNA profiling from these substrates is promising in the absence of other commonly found body fluids such as blood or saliva.
Watery eyes can occur when yawning pulls on and stimulates the lacrimal glands , which produces tears. In some cases, the eyes may also be dry from fatigue , causing them to tear up. Not everyone's eyes tear up when they yawn. Even in people who do experience this sensation, it may only occur occasionally.
For emotional tears to kick in, your limbic system — the part of your brain that regulates emotions — sends a signal to your brain's message system to activate your lacrimal glands to produce tears. The result? A full-on cry-fest. When you make a lot of them, they overwhelm your tear ducts.
Technically, the components of sweat are not the same as those of tears. Sweat is filtered lest it should discharge some essential components included in plasma. Anyway, both of the two are made of blood and play an important role in supporting our lives.
Research finds that tears are actually composed of a salt water layer sandwiched between a layer of fat and a layer of mucus, the better to keep the surface of the eye moist.
The physical downsides of crying are pretty straightforward: puffy eyes, splotchy skin and a headachy feeling that can be chalked up to the strong contractions of your facial muscles while you weep and pressure in your sinuses from the runny nose that accompanies a tear-fest.
After a late night or a good cry, anyone can experience bags under their eyes. But for some of us, the bags last long after the tears have dried. For some people, the bags appear puffy and swollen.

It's OK to let your baby cry if the baby doesn't seem sick and you've tried everything to soothe your baby. You can try to leave your baby alone in a safe place, such as a crib, for about 10 to 15 minutes. Many babies need to cry before they can fall asleep. And they'll nod off faster if you leave them to cry.
The emotion that brings on your tears also affects how they taste. Sad tears are more acidic which makes them taste sour. Angry tears contain more sodium and so are very salty, like your angry attitude. Happy tears taste sweeter, just like the moments that bring them on.
Our tears are made up of three components: lipid (oil), water and mucus. Each of these layers serves their own purpose. The oily layer is the outside of the tear film. It smooths the tear surface and keeps your tears from drying up too quickly.
Tears of sadness are usually caused by a prolonged emotional experience, which can lead to increased body temperature, resulting in warm tears.
