Here are 10 amazing facts about the human body you may not know:
How much saliva do we produce?
Saliva is created by glands in your mouth and it helps to keep your mouth moist and your teeth clean. It also helps you to digest the food that you’re drooling over.
Without saliva, we wouldn’t even be able to taste our food. Our body produces saliva at a rate of 30 milliliters an hour.
More when you’re eating and less when you’re sleeping. That’s an entire wine bottle full a day. In an average lifetime, human produce enough saliva to fill 53 bathtubs or two swimming pool.
Women are colder than men
If human is all warm-blooded so why does it seem like women are always colder than men? It is just a large-scale conspiracy to acquire all the world’s hoodies.
Turns out there’s the slightly more reasonable explanation. Women have higher core body temperatures than men.
Which means that since our bodies are used to being warm, we feel the cold work believe in men. This goes double for women on birth control.
As the hormones increased, temperature even further. Men also have metabolisms about 23% faster than women.
Your metabolism is the rate, your body burns food for energy. So the faster your body is working the warmer you feel.
While our metabolism may be slower, our bodies are better about conserving heat to a central area. Women’s bodies pull the warmth from their extremities to their internal organs resulting in icy cold feet and hands. see…. perfectly reasonable explanation!
Unique ear shape
Fingerprint evidence is frequently used in courtroom dramas, but there could be better ways to identify people.
We are born with our ears fully formed and they’re unique than most people in real life. Where fingerprints can rub off or become callous through hard labour.
You don’t have that problem and they generally remain consistent. Your identification is roughly the same if not better than facial recognition. Scientists have been developing a program to measure the biometrics of the human ear.
When it comes to identifying people, it is 99.6% accurate. Since ears can be hidden, scientists hope this technology can be used to complement existing fingerprint and DNA evidence and not replace it entirely.
Different kinds of sweat
Your body has 2 to 4 million sweat glands. But did you know that your body actually produces two different kinds of sweat?
Our sweat starts producing in reaction to certain stimuli. These include Heat, Hormones, Emotions or Exercise.
The majority of your sweat glands are Eccrine glands. These are the glands to blame when you’re trying to wipe your sweaty palms off on your team.
While embarrassing it’s odourless. It’s basically just salt in water. However, under our armpits work per Apocrine glands. The sweat produced by these glands contains an oily substance.
When this meets up with the bacteria on our skin, it produces an unpleasant odor. This is why we wear deodorant to combat the sweat on our armpits but not for the rest of our body. Wellll….most of us at least.
Noses are our most sensitive organ
Our brains can’t feel pain
When we step on a Lego, we instantly feel an incredible amount of pain. This is because our feet send a message to our brain via our spinal cord.
The brain confirms that. Yes, that hurt and then we can commence with the crying and self-pity. But the brain itself is actually incapable of feeling pain. This is because the brain doesn’t have any pain receptors.
When you have a headache it isn’t actually your brain that’s hurting. It’s a protective membrane surrounding your brain. When chemicals are released from the blood vessels near the brain, this activates the pain receptors causing headaches.
If blood flow increases during this time it can cause a migraine. This is especially useful during brain surgery. Patients remain awake so surgeon finisher, they don’t enter the speech centres of the brain. Once the brain is exposed, surgeons can work on the brain without causing any pain to the patient.
Metals dissolving stomach acids
Germs enter our bodies when we eat and breathe and gastric acid helps prevent them from spreading elsewhere in the body. This acid is comprised of hydrochloric acid, potassium chloride, and sodium chloride.
This chemical cocktail is strong enough to eat through razor blades. It’s actually a combination quite similar to battery acid. But don’t worry about the acid hurting your stomach. The cells in your stomach renew themselves so quickly every three to four days, but they don’t get damaged by the acid.
Anyone has had acid reflux knows the power of stomach acid in an unfit container. Acid reflux acrosses stomach acid rises into the oesophagus which isn’t designed to handle it and thus is incredibly painful.

Back dimple ( Dimples of Venus )
We have all seen people with dimples on their cheeks but sometimes they lurk where you might not expect them.
In the 16th century, Michelangelo coined the term “DIMPLES OF VENUS” to describe the two dimples some people have on their lower back.
While naming unique body quirks is one of his lesser-known talents that name stuck and is still used today. These dimples are much more common in women than men. But Michelangelo referred to the ones on men as dimples of Apollo.
These indents are thought to be genetic and are caused by a shortened ligaments stretching between the iliac spine and the skin. They allegedly improve circulation in that area of the body. Some people find them so aesthetically pleasing that they even get cosmetic surgery to get their very own dimples of Venus.
So basically, all of us humans are just hate shifting beings with brains unable to feel pain and our bodies are full of acids strong enough to dissolve metal. Sounds a lot cooler ….when we put it like that, right 😆 ?? Do a lot of the things you’ve experienced with your own body suddenly make sense ?? Tell us in the comments.
